This PR adds tsconfigs for each separate application: - `src/tsconfig.app.json`: configuration for the Angular app. - `src/tsconfig.spec.json`: configuration for the unit tests. Defaults to the Angular app config. - `e2e/tsconfig.e2e.json`: configuration for the e2e tests. There is an additional root-level `tsconfig.json` that is used for editor integration. For Angular version 4 projects, these tsconfigs will use inheritance since it's available with TypeScript 2.1. This is not a breaking change. Existing projects should not be affected.

# 3rd Party Library Installation
|
|
|
|
Simply install your library via `npm install lib-name --save` and import it in your code.
|
|
|
|
If the library does not include typings, you can install them using npm:
|
|
|
|
```bash
|
|
npm install d3 --save
|
|
npm install @types/d3 --save-dev
|
|
```
|
|
|
|
Then open `src/tsconfig.app.json` and add it to the `types` array:
|
|
|
|
```
|
|
"types":[
|
|
"d3"
|
|
]
|
|
```
|
|
|
|
If the library you added typings for is only to be used on your e2e tests,
|
|
instead use `e2e/tsconfig.e2e.json`.
|
|
The same goes for unit tests and `src/tsconfig.spec.json`.
|
|
|
|
If the library doesn't have typings available at `@types/`, you can still use it by
|
|
manually adding typings for it:
|
|
|
|
1. First, create a `typings.d.ts` file in your `src/` folder. This file will be automatically included as global type definition.
|
|
|
|
2. Then, in `src/typings.d.ts`, add the following code:
|
|
|
|
```typescript
|
|
declare module 'typeless-package';
|
|
```
|
|
|
|
3. Finally, in the component or file that uses the library, add the following code:
|
|
|
|
```typescript
|
|
import * as typelessPackage from 'typeless-package';
|
|
typelessPackage.method();
|
|
```
|
|
|
|
Done. Note: you might need or find useful to define more typings for the library that you're trying to use.
