## Development setup
|
|
|
|
We welcome any quality bugfixes or contributions!
|
|
|
|
To avoid conflicts with your existing installation, it is recommended to delete the installed extension at:
|
|
|
|
- **Linux and macOS**: `~/.vscode/extensions/msjsdiag.vscode-react-native-<version>`
|
|
- **Windows**: `C:\Users\<username>\.vscode\extensions\msjsdiag.vscode-react-native-<version>`
|
|
|
|
## Build the project
|
|
|
|
- `git clone https://github.com/microsoft/vscode-react-native.git`
|
|
- `cd vscode-react-native`
|
|
- Run `npm ci`
|
|
- Run `npm install -g gulp-cli` and add `"gulp.autoDetect": "on"` to your VS Code settings
|
|
- Run `gulp` and check `dist` folder for extension files (now the tasks from gulpfile.js are being exported following the latest guidance from https://gulpjs.com/docs/en/getting-started/creating-tasks/ as the task() API isn't the recommended pattern anymore)
|
|
- After completing above steps, run `gulp release` to package extension `.vsix` file. A VSIX package can help you install the latest extension maunally in VS Code extension tab.
|
|
|
|
## Debugging
|
|
|
|
There are currently 2 components to our extension: The extension running in the VS Code process with the debug adapter, and some code wrapping the user React Native code which is launched by the debug adapter. These are all debugged in different ways:
|
|
|
|
- To debug the extension process itself and the debug adapter it provides, in VS Code run the `Launch Extension` debug target which will spawn a new instance of VS Code with the extension installed. You can set breakpoints in the Typescript and debug things such as extension activation and the command palette.
|
|
|
|
- To debug the code running in the same process as the React Native code, open a React Native project, start debugging and find the `debuggerWorker.js` file where you can set a breakpoint. This file is generated by Metro bundler, but modified by the extension and saved in your React Native `.vscode/.react` folder locally. The file is created only when you start debugging against your React Native application and the debugger is already attached to it. The `debuggerWorker.js` is launched in `--inspect-brk` mode so it will wait until debugger is attached to the app.
|
|
|
|
- To debug the gulpfile.js, add a configuration to .vscode/launch.json to run "${workspaceRoot}/node_modules/gulp/bin/gulp.js". Then we can run it through "Run and Debug" tab in VS Code.
|
|
|
|
## Testing
|
|
|
|
There is a set of Mocha tests for the extension and extension localization which can be run with `npm test` and `npm run test-localization` or by `Launch Extension Tests` and `Launch Localization Tests`. Also there are e2e smoke tests placed in [`test/smoke`](https://github.com/microsoft/vscode-react-native/tree/master/test/smoke) folder that can be launched by `yarn smoke-tests` command or by `Launch All Smoke Tests` command. Make sure to [prepare test environment](https://github.com/microsoft/vscode-react-native/blob/master/test/smoke/docs/run-locally.md) before launching e2e tests.
|
|
|
|
Run `gulp lint` to check your code against our linting rules or `gulp format` to try to auto fix all linting problems with Prettier.

## Sending a PR
|
|
|
|
Pull requests should:
|
|
|
|
- Include a clear description of the proposed change
|
|
- Be a child commit of a reasonably recent commit in the **master** branch
|
|
- Requests need not be a single commit, but should be a linear sequence of commits (i.e. no merge commits in your PR)
|
|
- Have clear commit messages
|
|
- e.g. "Refactor feature", "Fix issue", "Add tests for issue"
|
|
- Include adequate tests
|
|
- At least one test should fail in the absence of your non-test code changes. If your PR does not match this criteria, please specify why
|
|
- Tests should include reasonable permutations of the target fix/change
|
|
- Include baseline changes with your change
|
|
- Have linting issues (`gulp lint`)
|
|
|
|
It is desirable, but not necessary, for the tests to pass at each commit.
|
|
|
|
To avoid line ending issues, set `autocrlf = input` and `whitespace = cr-at-eol` in your system's git configuration.
