Angular2 Build: Cannot find name 'Promise' only in Visual Studio - javascript

I am getting started with Angular2 and followed the quickstart here: https://angular.io/guide/quickstart
It seems to work fine when I do npm install but I want to run it in Visual Studio and I will be making in Asp.Net/C# and not NodeJS.
When I build the solution in VS I get this:
I think in nodejS it works because in the package.json we have this:
"postinstall": "typings install",
entire package.json
{
"name": "angular2-quickstart",
"version": "1.0.0",
"scripts": {
"start": "tsc && concurrently \"npm run tsc:w\" \"npm run lite\" ",
"lite": "lite-server",
"postinstall": "typings install",
"tsc": "tsc",
"tsc:w": "tsc -w",
"typings": "typings"
},

"dependencies": {

"concurrently": "^2.0.0",
"lite-server": "^2.2.0",
"typescript": "^1.8.10",
"typings": "^1.0.4"
}
}
But problem is I am using Visual studio. How can I just build the solution and make it run without using npm start

I think you must use es6-shim to get these errors away. Try this:
typings install dt~es6-shim --save --global
This fixed the problem for me.

I made sure angular package versions are aligned to get the build successful.

Just add npx before ng serve like this npx ng serve
If you have installed the dependencies locally and need to refer those packages instead of global. use npx before the the command eg: npx ng serve refers to the locally installed package. ng serve refers to the global package.
npm version 5.2+

I am unable to install my project packages

I was getting error installing expressJs to my packages. I have had to do an npm cache clean --force no sucess, then I deleted my node_modules and package-lock.json, I try to reinstall packages using npm i I still got an error.
Now I deleted node.js from my pc windows 10 and downloaded and installed the latest node and tried to reinstall the project packages again. Now the error I get is this

Apparently error is from my pc cause it works just fine on another pc.
I don't know much about npm, but I'd suggesting trying to have it verify the installs it's already done and somehow rewrite the package.json file from the existing installs.
https://docs.npmjs.com/cli/cache.html
Even though the install failed and the package.json doesn't show any traces of the install, there could be some artifact that only npm knows about that's getting in the way.

I also faced the same problem and solved by downgrading yarn version to 1.10.1, then it works. May it work for you as well.
Uninstall yarn 1.12.3
Install yarn 1.10.1
Go to project folder and execute yarn install
Build my project and the error is gone
Delete the node_module folder and then run npm install.

Why is my Heroku build failing?

my heroku build is failing. I am trying to build an Angular 4 application on Heroku but it won't let me. I have a feeling it is missing a package.json dependency but I am not sure.

It fails because there is no ng command available. It's provided by #angular/cli, if moving it to required dependencies and executing local binary doesn't work, then try to change your preinstall script to:
"preinstall": "npm i -g http-server && npm i -g #angular/cli",
In postinstall, you are using ng executable supposing it's installed globally.
Since ng is also one of your dependencies, you could change it to
"postinstall": "./node_modules/.bin/ng build --prod"
Beacause #angular/cli is not installed on deployed machine using ng build in script wont work.
Do this
"scripts": {
...
"build:prod": "ng build --prod",
"heroku-postbuild": "npm run build:prod"
},
Things to note. use heroku-postbuild instead of postinstall. And running a npm script which uses local package (ng in this case) works. But directly running ng build --prod in npm script wont run.

ionic 2 serve ignores changes in html

I am starting an ionic2 project, and running into trouble with seeing changes in code reflect to the browser.
Description of the phenomenon:
At some point I see all of what I expect to see in the browser. For example, a single page whose .html is
{{text}}
and text field in the .ts contains "hola".
The output is obviously hola.
Then, I either can change the .html to
Hello World!
Or the text field in the .ts to "mundo"
Since ionic serve is running in the background, I see the browser update itself after I save the change in the code.
However, it always updates to the same old hola.
Doesn't matter how many times I refresh, save, change. I can even delete all contents of both .html and .ts files, and still the browser would show the old state.
things I tried that don't work:
clearing cache from chrome
restarting ionic serve
saving any and all files again
refreshing browser.
It is very frustrating to work like this, as this problem comes and goes, and I have no clear method to even bypass it.
Any suggestions?
I run windows 10, and this happens both in chrome and firefox.

This happened to me and I had to switch to using Google Chrome Icognito mode. Caching of javascript seemed to mess things up in development.
First run in your project folder npm run clean to do a clean then npm run build to rebuild before serving again.
