angular jasmine-node not installing via node npm - javascript

I've tried a few times to install my first AngularJS project via their docs:
https://docs.angularjs.org/misc/contribute
*# Clone your Github repository:
git clone "git#github.com:<github username>/angular.js.git"
# Go to the AngularJS directory:
cd angular.js
# Add the main AngularJS repository as an upstream remote to your repository:
git remote add upstream "https://github.com/angular/angular.js.git"
# Install node.js dependencies:
npm install
# Install bower components:
bower install
# Build AngularJS:
grunt package*
Each time I try to npm install it returns an error for jasmine-node
I've searched for solutions and tried a bunch of methods & hopeful tests but still not receiving back any luck.
Much appreciated for any help, guys!

Those docs are for people who want to contribute (work on angularjs library) and not for people who are building projects using angular. To me, it seems that you'd want the latter.
There are plenty of tutorials out there, just search for angularjs beginner tutorial, and find the one that suits you the most.

An issue I was frequently experiencing was protocol issues due to npm errors being returned especially for Bower.
You can make git replace the protocol for you. Just run:
git config --global url."https://".insteadOf git://
Apologies if this thread is a bit of a mess, but hope it helps someone out there too.

How can I install NPM dependencies?

I've got a task that involves writing a code and I carried it out quite easily. I need to submit my solution to GitHub – according to the plan, I forked a certain repository and even cloned it to my hard drive using VS code. However, I was also told to install NPM dependencies to that newly created folder.
There are many manuals on Internet, but almost no one of them explains how to do it in a comprehensible way. As a beginner, I often struggle with all these new keywords, commands, etc and I would like to make things somewhat clearer. Do you have an idea how to get through it?
If you have already installed npm, in project directory use command
npm install
You can start with npm init in your folder. Then package.json file will be created. you can add dependencies you want to add, and run npm install.

Trouble installing with d3-context-menu with bower using VS code

I am trying to install the d3-context-menu for my vue js and d3.js web app. For reference here is the github here I don't have bower installed so I installed it using
npm install -g bower
Then I ran the command
bower install d3-context-menu
However I get the error message
bower ESUDO Cannot be run with sudo
Additional error details:
Since bower is a user command, there is no need to execute it with superuser permissions.
If you're having permission errors when using bower without sudo, please spend a few minutes learning more about how your system should work and make any necessary repairs.
http://www.joyent.com/blog/installing-node-and-npm
https://gist.github.com/isaacs/579814
You can however run a command with sudo using "--allow-root" option
I looked this up online and I cannot find a fix. Would this be because of me using d3v6 or that the context menu github is outdated?
Or is their a better alternative to create a context menu using d3.js?
I am very new to this so any help is greatly appreciated. Thank you
You can use this package in two other ways.
Some examples are described in the README file, here and here, where the author uses the package including the script tag directly in HTML.
<link rel="stylesheet" href="d3-context-menu.css" />
<script src="d3-context-menu.js"></script>
A second way is to install the package using npm. This package is published in the npm registry: https://www.npmjs.com/package/d3-context-menu.
So, theoretically, all you need is:
npm i d3-context-menu
I haven't tested the second way, but the canonical form can be tested directly in the online environment where the examples are, the Plunker platform and it works.

How to install Redux after creating a React application using create-react-app?

Created an application using create-react-app. I wrote just the word test in the render method to display on the screen. And everything is ok.
Then I write: npm install --save redux for the folder with the application and the application does not work.
In console error:
How then to install redux after create-react-app? What is the procedure step by step?
Or Maybe you know some article where they describe step by step? Or do you know some video on YouTube?
When you installed redux you might have mispelled it while installing because in your screenshot see the error carefully it is shown the redux spelling as 'redx' so try fixing it by installing correctly with npm or try with yarn.
To do with npm :-
npm i redux --save
And if you want to install any packages with yarn you can do so with following command :-
yarn add redux
The other thing I have seen in your image is that there is an error of #babel/runtime if the error is coming again after installing redux correctly then you might have to install it manually.
First you need to remove the node_modules completely and then install the #babel/runtime package
To do with npm :-
npm i #babel/runtime --save OR npm add #babel/runtime
I know it might be late but I have written a Step-by-Step guide on "How to Add Redux into create-react-app".
You can find the link of the blog here.
https://www.realmelon.com/react-redux-how-to-add-redux-into-create-react-app/
Moreover, I have uploaded the Video for the same.

If you still find any issues in installing "Redux on React", please let me know
Happy Learning

Resolve npm dependencies from workspace in VSCode?

I come from Java world and I'm used to code with Maven and Eclipse, which makes very easy to work with local dependencies as the IDE + M2Eclipse plugin is able to resolve dependencies from the workspace.
Now that I'm developing in JavaScript with NPM and VS Code, I find that you have to use manual options such as npm link + npm build --watch or npm pack + npm install <path> to work with local dependencies.
I'm developing an Angular application which codebase is split in different Git projects and npm packages, so we waste a lot of time testing local dependencies and also it is error prone.
I guess that this is caused by the different nature of JavaScript and Npm but, is there any plugin or option to ease local depevelopment in VS Code?
EDIT: I have seen this article about Yarn Workspaces and it looks like what I'm looking for... anything similar in npm? I see Lerna is an option but only for monorepos, I have separated Git repos for each library.
EDIT2: To clarify the problem, lets say I'm developing two Angular libraries, each on a different Angular workspace. Library A depends on library B. I use VS Code workspace to have these two Angular workspaces open at the same time and edit them together. If I change library B I have to build it and link it so that I can test the changes locally in library A before publishing. This is what "resolve dependencies from the workspace" solves in Eclipse + M2Eclipse in Java, the IDE just builds and links projects together. Thats what I'm looking for in VS Code + NPM in Angular.
EDIT3: New workspaces feature in NPM 7 looks promising, I will give it a try. Any thoughts about it?

React dev dependencies vs dependencies [duplicate]

This documentation answers my question very poorly. I didn't understand those explanations. Can someone say in simpler words? Maybe with examples if it's hard to choose simple words?
EDIT also added peerDependencies, which is closely related and might cause confusion.
Summary of important behavior differences:
dependencies are installed on both:
npm install from a directory that contains package.json
npm install $package on any other directory
devDependencies are:
also installed on npm install on a directory that contains package.json, unless you pass the --production flag (go upvote Gayan Charith's answer), or if the NODE_ENV=production environment variable is set
not installed on npm install "$package" on any other directory, unless you give it the --dev option.
are not installed transitively.
peerDependencies:
before 3.0: are always installed if missing, and raise an error if multiple incompatible versions of the dependency would be used by different dependencies.
expected to start on 3.0 (untested): give a warning if missing on npm install, and you have to solve the dependency yourself manually. When running, if the dependency is missing, you get an error (mentioned by #nextgentech) This explains it nicely: https://flaviocopes.com/npm-peer-dependencies/
in version 7 peerDependencies are automatically installed unless an upstream dependency conflict is present that cannot be automatically resolved
Transitivity (mentioned by Ben Hutchison):
dependencies are installed transitively: if A requires B, and B requires C, then C gets installed, otherwise, B could not work, and neither would A.
devDependencies is not installed transitively. E.g. we don't need to test B to test A, so B's testing dependencies can be left out.
Related options not discussed here:
bundledDependencies which is discussed on the following question: Advantages of bundledDependencies over normal dependencies in npm
optionalDependencies (mentioned by Aidan Feldman)
devDependencies
dependencies are required to run, devDependencies only to develop, e.g.: unit tests, CoffeeScript to JavaScript transpilation, minification, ...
If you are going to develop a package, you download it (e.g. via git clone), go to its root which contains package.json, and run:
npm install
Since you have the actual source, it is clear that you want to develop it, so by default, both dependencies (since you must, of course, run to develop) and devDependency dependencies are also installed.
If however, you are only an end user who just wants to install a package to use it, you will do from any directory:
npm install "$package"
In that case, you normally don't want the development dependencies, so you just get what is needed to use the package: dependencies.
If you really want to install development packages in that case, you can set the dev configuration option to true, possibly from the command line as:
npm install "$package" --dev
The option is false by default since this is a much less common case.
peerDependencies
(Tested before 3.0)
Source: https://nodejs.org/en/blog/npm/peer-dependencies/
With regular dependencies, you can have multiple versions of the dependency: it's simply installed inside the node_modules of the dependency.
E.g. if dependency1 and dependency2 both depend on dependency3 at different versions the project tree will look like:
root/node_modules/
|
+- dependency1/node_modules/
| |
| +- dependency3 v1.0/
|
|
+- dependency2/node_modules/
|
+- dependency3 v2.0/
Plugins, however, are packages that normally don't require the other package, which is called the host in this context. Instead:
plugins are required by the host
plugins offer a standard interface that the host expects to find
only the host will be called directly by the user, so there must be a single version of it.
E.g. if dependency1 and dependency2 peer depend on dependency3, the project tree will look like:
root/node_modules/
|
+- dependency1/
|
+- dependency2/
|
+- dependency3 v1.0/
This happens even though you never mention dependency3 in your package.json file.
I think this is an instance of the Inversion of Control design pattern.
A prototypical example of peer dependencies is Grunt, the host, and its plugins.
For example, on a Grunt plugin like https://github.com/gruntjs/grunt-contrib-uglify, you will see that:
grunt is a peer-dependency
the only require('grunt') is under tests/: it's not actually used by the program.
Then, when the user will use a plugin, he will implicitly require the plugin from the Gruntfile by adding a grunt.loadNpmTasks('grunt-contrib-uglify') line, but it's grunt that the user will call directly.
This would not work then if each plugin required a different Grunt version.
Manual
I think the documentation answers the question quite well, maybe you are just not familiar enough with node / other package managers. I probably only understand it because I know a bit about Ruby bundler.
The key line is:
These things will be installed when doing npm link or npm install from the root of a package and can be managed like any other npm configuration parameter. See npm-config(7) for more on the topic.
And then under npm-config(7) find dev:
Default: false
Type: Boolean
Install dev-dependencies along with packages.
If you do not want to install devDependencies you can use npm install --production
As an example, mocha would normally be a devDependency, since testing isn't necessary in production, while express would be a dependency.
dependencies
Dependencies that your project needs to run, like a library that provides functions that you call from your code.
They are installed transitively (if A depends on B depends on C, npm install on A will install B and C).
Example: lodash: your project calls some lodash functions.
devDependencies
Dependencies you only need during development or releasing, like compilers that take your code and compile it into javascript, test frameworks or documentation generators.
They are not installed transitively (if A depends on B dev-depends on C, npm install on A will install B only).
Example: grunt: your project uses grunt to build itself.
peerDependencies
Dependencies that your project hooks into, or modifies, in the parent project, usually a plugin for some other library or tool. It is just intended to be a check, making sure that the parent project (project that will depend on your project) has a dependency on the project you hook into. So if you make a plugin C that adds functionality to library B, then someone making a project A will need to have a dependency on B if they have a dependency on C.
They are not installed (unless npm < 3), they are only checked for.
Example: grunt: your project adds functionality to grunt and can only be used on projects that use grunt.
This documentation explains peer dependencies really well: https://nodejs.org/en/blog/npm/peer-dependencies/
Also, the npm documentation has been improved over time, and now has better explanations of the different types of dependencies: https://github.com/npm/cli/blob/latest/docs/content/configuring-npm/package-json.md#devdependencies
To save a package to package.json as dev dependencies:
npm install "$package" --save-dev
When you run npm install it will install both devDependencies and dependencies. To avoid install devDependencies run:
npm install --production
There are some modules and packages only necessary for development, which are not needed in production. Like it says it in the documentation:
If someone is planning on downloading and using your module in their program, then they probably don't want or need to download and build the external test or documentation framework that you use. In this case, it's best to list these additional items in a devDependencies hash.
peerDependencies didn't quite make sense for me until I read this snippet from a blog post on the topic Ciro mentioned above:
What [plugins] need is a way of expressing these “dependencies” between plugins and their host package. Some way of saying, “I only work when plugged in to version 1.2.x of my host package, so if you install me, be sure that it’s alongside a compatible host.” We call this relationship a peer dependency.
The plugin does expect a specific version of the host...
peerDependencies are for plugins, libraries that require a "host" library to perform their function, but may have been written at a time before the latest version of the host was released.
That is, if I write PluginX v1 for HostLibraryX v3 and walk away, there's no guarantee PluginX v1 will work when HostLibraryX v4 (or even HostLibraryX v3.0.1) is released.
... but the plugin doesn't depend on the host...
From the point of view of the plugin, it only adds functions to the host library. I don't really "need" the host to add a dependency to a plugin, and plugins often don't literally depend on their host. If you don't have the host, the plugin harmlessly does nothing.
This means dependencies isn't really the right concept for plugins.
Even worse, if my host was treated like a dependency, we'd end up in this situation that the same blog post mentions (edited a little to use this answer's made up host & plugin):
But now, [if we treat the contemporary version of HostLibraryX as a dependency for PluginX,] running npm install results in the unexpected dependency graph of
├── HostLibraryX#4.0.0
└─┬ PluginX#1.0.0
└── HostLibraryX#3.0.0
I’ll leave the subtle failures that come from the plugin using a different [HostLibraryX] API than the main application to your imagination.
... and the host obviously doesn't depend on the plugin...
... that's the whole point of plugins. Now if the host was nice enough to include dependency information for all of its plugins, that'd solve the problem, but that'd also introduce a huge new cultural problem: plugin management!
The whole point of plugins is that they can pair up anonymously. In a perfect world, having the host manage 'em all would be neat & tidy, but we're not going to require libraries herd cats.
If we're not hierarchically dependent, maybe we're intradependent peers...
Instead, we have the concept of being peers. Neither host nor plugin sits in the other's dependency bucket. Both live at the same level of the dependency graph.
... but this is not an automatable relationship. <<< Moneyball!!!
If I'm PluginX v1 and expect a peer of (that is, have a peerDependency of) HostLibraryX v3, I'll say so. If you've auto-upgraded to the latest HostLibraryX v4 (note that's version 4) AND have Plugin v1 installed, you need to know, right?
npm can't manage this situation for me --
"Hey, I see you're using PluginX v1! I'm automatically downgrading HostLibraryX from v4 to v3, kk?"
... or...
"Hey I see you're using PluginX v1. That expects HostLibraryX v3, which you've left in the dust during your last update. To be safe, I'm automatically uninstalling Plugin v1!!1!
How about no, npm?!
So npm doesn't. It alerts you to the situation, and lets you figure out if HostLibraryX v4 is a suitable peer for Plugin v1.
Coda
Good peerDependency management in plugins will make this concept work more intuitively in practice. From the blog post, yet again...
One piece of advice: peer dependency requirements, unlike those for regular dependencies, should be lenient. You should not lock your peer dependencies down to specific patch versions. It would be really annoying if one Chai plugin peer-depended on Chai 1.4.1, while another depended on Chai 1.5.0, simply because the authors were lazy and didn’t spend the time figuring out the actual minimum version of Chai they are compatible with.
A simple explanation that made it more clear to me is:
When you deploy your app, modules in dependencies need to be installed or your app won't work. Modules in devDependencies don't need to be installed on the production server since you're not developing on that machine.
link
I found a simple explanation.
Short Answer:
dependencies
"...are those that your project really needs to be able to work in production."
devDependencies
"...are those that you need during development."
peerDependencies
"if you want to create and publish your own library so that it can be used as a dependency"
More details in this post:
https://code-trotter.com/web/dependencies-vs-devdependencies-vs-peerdependencies
I'd like to add to the answer my view on these dependencies explanations
dependencies are used for direct usage in your codebase, things that usually end up in the production code, or chunks of code
devDependencies are used for the build process, tools that help you manage how the end code will end up, third party test modules, (ex. webpack stuff)
In short
Dependencies - npm install <package> --save-prod installs packages required by your application in production environment.
DevDependencies - npm install <package> --save-dev installs
packages required only for local development and testing
Just typing npm install installs all packages mentioned in the
package.json
so if you are working on your local computer just type npm install and continue :)
Dependencies vs dev dependencies
Dev dependencies are modules which are only required during development whereas dependencies are required at runtime. If you are deploying your application, dependencies has to be installed, or else your app simply will not work. Libraries that you call from your code that enables the program to run can be considered as dependencies.
Eg- React , React - dom
Dev dependency modules need not be installed in the production server since you are not gonna develop in that machine .compilers that covert your code to javascript , test frameworks and document generators can be considered as dev-dependencies since they are only required during development .
Eg- ESLint , Babel , webpack
#FYI,
mod-a
dev-dependents:
- mod-b
dependents:
- mod-c
mod-d
 dev-dependents:
- mod-e
dependents:
- mod-a
----
npm install mod-d
installed modules:
- mod-d
- mod-a
- mod-c
----
checkout the mod-d code repository
npm install
installed modules:
- mod-a
- mod-c
- mod-e
If you are publishing to npm, then it is important that you use the correct flag for the correct modules. If it is something that your npm module needs to function, then use the "--save" flag to save the module as a dependency. If it is something that your module doesn't need to function but it is needed for testing, then use the "--save-dev" flag.
# For dependent modules
npm install dependent-module --save
# For dev-dependent modules
npm install development-module --save-dev
Dependencies
These are the packages that your package needs to run, so they will be installed when people run
npm install PACKAGE-NAME
An example would be if you used jQuery in your project. If someone doesn't have jQuery installed, then it wouldn't work. To save as a dependency, use
npm install --save
Dev-Dependencies
These are the dependencies that you use in development, but isn't needed when people are using it, so when people run npm install, it won't install them since the are not necessary. For example, if you use mocha to test, people don't need mocha to run, so npm install doesn't install it. To save as a dev dependency, use
npm install PACKAGE --save-dev
Peer Dependencies
These can be used if you want to create and publish your own library so that it can be used as a dependency. For example, if you want your package to be used as a dependency in another project, then these will also be installed when someone installs the project which has your project as a dependency. Most of the time you won't use peer dependencies.
dependencies: packages that your project/package needs to work in production.
devDependencies: packages that your project/package needs to work while development but are not needed on production (eg: testing packages)
peerDependencies: packages that your project/package needs to work in tandem with (“colaborating” with them) or as a base, useful mainly when you are developing a plugin/component to let know with which version of the “main” package your plugin/component is supposed to work with (eg: React 16)
When trying to distribute an npm package you should avoid using dependencies. Instead you need to consider adding it into peerDependencies.
Update
Most of the time dependencies are just a bunch of libraries that describes your ecosystem. Unless, you're really using a specific version of a library you should instead let the user choose whether or not to install that library and which version to choose by adding it into the peerDependencies.
dependencies are required to run, devDependencies only to develop
When using Webpack to bundle a frontend application, the distinction between dependencies and devDependencies is not so clear. For the final bundle, it doesn't matter where you place the dependencies (but it may be important for other tools). That's why the documentation seems confusing.
I found the explanation here: Do "dependencies" and "devDependencies" matter when using Webpack?
