I have this project:
but I don't know how to run the generate_js.js in my browser so I can see use console.log inside of the file.
The whole purpose of this project is to run generate_js.js, which is then supposed to generate an icon.js file which contains the svg icons in a particular object format/structure. But what happens when I run generate_js.js is that a folder generate_js is created with all the icons as js files, and each file has an export statement.
I am trying to understand how is all of this working, but I can't. I need to be able to see what's happening on my browser. I need to use console.log to see, but I don't know how to run this project on my browser. There is no index.html file, and when I created one, and linked the project_js.js with a script tag, I keep getting Uncaught ReferenceError: require is not defined error.
How can I run this JavaScript/project on my browser?
Here's the relevant part of package json:
Note: This project is installed as a dependency inside another project, and inside the node_modules, there's a dist folder which contains the icons.js file that I referred to. In it, all the icons are created as objects. I need to change the way the object structure a bit, so I need to understand how are they generated by this generate.js file, but I need to be able to console.log what's happening inside the file.

What I want to do is add a custom script in package.json file that should run always before start and build scripts.
Things I want to do in my custom script:
Copy the favicon.ico file from /favicons/${process.env.REACT_APP_BRAND}.ico into /public, in order to overwrite the default one
Do a symlink from /src/assets/${process.env.REACT_APP_BRAND} to /src/assets/brand, in order to import images inside code without doing things like dynamic imports (which works but I think it's not their purpose)
I'm a bit lost with the structure of this custom script, and programming languange (its shell, but I'm on MacOS, so, it's better do it in node?)
Thank you.
I've finished making an app with HTML, CSS, and JS files, all of which I've stored in the 'assets' folder of Android Studio.
The app runs without crashing, but only this screen appears:
Empty app screen.
I've tried implementing each of the following file paths:
webView.loadUrl("file:///assets/menu.html");
webView.loadUrl("menu.html");
Neither of them work.
I've read that it's ideal to create a new folder in 'main' and call it 'android_assets' and then name the file path ("file:///android_assets/menu.html"); but I don't want to inadvertently create more problems in my code.
Should I create the 'android_assets' folder? Is there anything I'd risk in doing so?
Try this:
1.
Ensure your assets path is: assets/foldersIfAny/index.html
2.
Then use this:
webView.loadUrl("file:///android_asset/foldersIfAny/index.html");
I'm trying to add an external js file into my Angular2 project by adding the record to my angular-cli.json file.
I've added a file to the [scripts] array as below:
"scripts": ["https://as-identitydemo--c.na50.visual.force.com/resource/1495420277000/salesforce_login_widget_js"],
all the other posts that i've read refer to using this format for something that's either hosted locally, or installed in the node_modules etc..
How can I include an external js library and utilize that in my project?
You should import the library in your index.html in the head tag.
Second you have to make the library visible to your Angular project. That means you need the typings. You can either search https://github.com/DefinitelyTyped
for already existing types or add the types to the typings.d.ts file.
Example:
In your page (outside of the Angular app) you might have a javascript global variable:
var testVar = 'testvalue';
Then in the typings.d.ts you can make this variable globally accessible by adding
declare var testVar:string;
Then you can access this variable in the whole Angular project like that:
console.log(testVar);
The same you can do with functions in external libraries.
Here is a Plunk that shows that (without having a typings file). Hope this helps.
Attempting to wrap my head around Ember.js.
Seems I understand the complex things, but miss out on the little things.
How would one go about adding an example.js file?
For simplicity, let's say the example.js file only contains:
(function(){
console.log("example is alive in console");
})(window);
This should display "example is alive in console" within the browser console.
I have tried:
adding app.import('vendor/javascripts/example.js'); within ember-cli-build.js and adding <script src="{{rootURL}}vendor/javascripts/example.js"></script> to index.html
Console is showing
ⓧ GET http://localhost:4200/vendor/javascripts/example.js
DEBUG: -------------------------------
DEBUG: Ember : 2.11.3
DEBUG: Ember Data : 2.12.1
DEBUG: jQuery : 3.2.1

ⓧ GET http://localhost:4200/vendor/javascripts/example.js
All of the answers I have found stated that just adding custom.js to vendor file works. Sadly, I am missing something.
When modifying ember-cli-build.js you MUST RESTART the ember server manually. The livereload server will not pick up the changes.
This works for me when I don't nest assets in the /vendor directory. The ember-cli build process bundles JS files in /vendor into a single vendor.js file, which you can see linked in app/index.html. So place your example.js file at the root of /vendor, and then add the import to ember-cli-build.js:
app.import('vendor/example.js`);
Now when you start the server, your code from example.js should execute, since it will be included in assets/vendor.js.
Firstly, Ember.js has Convention Over Configuration approach, and your URL can do a lot of things than a normal HTML website.
Whatever you may want to do with your custom.js file it is not ember way of having it as a path. You need routes for navigation across the app. Although routes do much more than navigation. You specify the structure of your app that a user can browse through using Router's map function in app/router.js file.
However if you want to include custome.js file in your app, and have custom.js do some set of tasks for your app. You can simply go ahead and create a directory with any name, javascript for instance inside app directory. Have your javascript files placed inside it. Then you can import these files as simply as referencing any other files in ember:
import customObject from 'yourApp/javascript/custom.js';
Here, your custom.js should be exporting customObject.
Do read the guides if you want to learn more. And the API docs if you actually want to learn more.
Note: At the time of writing this answer current ember-cli version is #2.12.0
I'm trying to split my server in multiples files, and actually I want to make cmdb_login.js and main.js.
The thing is that I don't know and I don't find how to say in main.js, use cmdb_login.js.
I have tried import './cmdb_login.js';
My app structure is:
If you need the code of the two .js files just ask me.
Thank you for the help
As always, Meteor combines all files eagerly, unless they are placed in a path which includes a folder named imports.
I.e. in your case, your cmdb_login.js will be combined (and then executed) before main.js in the server JavaScript code.
A proper way is to put almost all your files in an imports folder, and explicitly call them in a single main.js file (or whatever its name, provided that it is not in an imports folder), using an import statement like the one you tried (e.g. import './imports/cmdb_login.js').
