Development Workflow
====================
## Project Structure
The repository contains several packages and apps:
- `tns-core-modules` - The core NativeScript TypeScript modules used to develop NativeScript apps.
- `apps` - UI app used for manual testing and automation.
- `e2e` - applications and *e2e* tests.
- `tests` - Unit tests app for the `tns-core-modules`.
- `tns-platform-declarations` - TypeScript definitions for Android and iOS native APIs.
Working with the repo is organized with npm scripts,
go and read through the `scripts` section in the [package.json](./package.json).
Managing dependencies:
- `tns-core-modules` depends on:
- `tns-platform-declarations`
- `apps` depends on:
- `tns-platform-declarations`
- `tns-core-modules`
- `e2e` depends on:
- `tns-core-modules`
- `tests` depends on:
- `tns-platform-declarations`
- `tns-core-modules`
> NOTE: `tns-core-modules` depends on `tns-core-modules-widgets`,
this dependency contains native code and is rarely modified so for now it remains outside this repo.
## Initial Setup
Clone (or fork/clone) the repo:
```bash
git clone https://github.com/NativeScript/NativeScript.git
```
Install devDependencies:
```bash
npm install
```
<!---
## TypeScript
The following commands are commonly used to compile the `tns-core-modules`:
```bash
# Full tsc with type checking ~22.2s.
tsc
# Fast tsc ~11.2s.
tsc --skipLibCheck
# Fast watcher, ~4s. on save
tsc --skipLibCheck -w
```
NOTE: transpile `tns-core-modules` only.
The modules have `typescript` as a devDependency so you should also be able to use the locally installed TypeScript compiler from node_modules:
```bash
./node_modules/.bin/tsc
```
You can compile the TypeScript files in the `tns-core-modules` and `tns-platform-declarations` at once at the root of the repo:
```bash
npm run tsc
```
--->
## Running Unit Tests
```
cd ./tests
tns run android| ios
```
## Running the Test App
The test app is an ordinary NativeScript app that logs the test results as it go.
After the [initial setup](#initial-setup) you can run the tests with:
```
# Make sure TypeScript is transpiled
tsc
# Run the app
tns run ios --path apps
tns run android --path apps
```
## Running Another App
The [initial setup](#initial-setup) will `npm-link` the `tns-core-modules` globally. You can use it in any local project:
```bash
# Run once: Link tns-core-modules in your project
npm link tns-core-modules
# Run the app
tns run ios
tns run android
```
> Note: You still have to rebuild the TypeScript if you have made changes in the code of the core-modules.
## Platform declarations
To update the platform declarations (the ios.d.ts-es) you can run:
```
npm install
npm run dev-declarations
```
This script will update the iOS declarations. Android tools are not integrated yet.
The declarations are generated from the test app and will include the native code from tns-core-modules-widgets.
# Documentation API reference
The following will build the API reference pages in `bin/dist/apiref`:
```
npm run typedoc
```
If you want to improve on the documentation you can also build and start up dev web server:
```
npm run dev-typedoc
```
The terminal will point the address you can open in your web browser.
