Quick Setup

Add the current version of jet as a development dependency using your package manager of choice, for example yarn:

``sh
yarn add --dev jet
`

These docs are still TODO, for now see example, in particular:

Configuring Jet and targets:

- .jetrc.js

Adding the test UI and your tests:

- App.tsx

Configuring coverage instrumentation:

- babel.config.js
- nyc.config.js

$3

`sh
jet --target=macos
`

$3

Example:

`js
const proc = require('node:child_process');

module.exports = {
config: {
// Global config overrides/defaults...
},
targets: {
// Use any key name to specify a new 'target' (--target=)
// [key: string]: { ... }
macos: {
// --target=macos
config: {
// Per target config overrides...
// These will override in order of:
// ...cliFlags
// ...globalConfig
// ...targetConfig
},
/**
* Use this to run builds, start the application etc.
*/
async before(config) {
proc.spawnSync('npx', ['react-native', 'run-macos']);
return config;
},
/**
* Use this for cleanup & teardown.
*/
async after(config) {
console.log('After');
},
},
},
};
``
