This is the mobile version of Gutenberg, targeting Android and iOS. It's a React Native library bootstrapped by CRNA and now ejected.
For a developer experience closer to the one the project maintainers current have, make sure you have the following tools installed:
- git
- nvm
- Node.js and npm (use nvm to install them)
- yarn (
npm install -g yarn
) - AndroidStudio to be able to compile the Android version of the app
- Xcode to be able to compile the iOS app
- Carthage needed for fetching the Aztec dependency.
Note that the OS platform used by the maintainers is macOS but the tools and setup should be usable in other platforms too.
- Clone the project and submodules:
git clone --recurse-submodules https://github.com/wordpress-mobile/gutenberg-mobile.git
- Or if you already have the project cloned, initialize and update the submodules:
git submodule init
git submodule update
Before running the demo app, you need to download and install the project dependencies. This is done via the following command:
nvm install --latest-npm
yarn install
yarn start
Runs the packager (Metro) in development mode. The packager stays running to serve the app bundle to the clients that request it.
With the packager running, open another terminal window and use the following command to compile and run the Android app:
yarn android
The app should now open in a connected device or a running emulator and fetch the JavaScript code from the running packager.
To compile and run the iOS variant of the app using the default simulator device, use:
yarn ios
which will attempt to open your app in the iOS Simulator if you're on a Mac and have it installed.
To compile and run the app using a different device simulator, use:
yarn ios --simulator="DEVICE_NAME"
For example, if you'd like to run in an iPhone Xs Max, try:
yarn ios --simulator="iPhone Xs Max"
To see a list of all of your available iOS devices, use xcrun simctl list devices
.
Some times, and especially when tweaking anything in the package.json
, Babel configuration (.babelrc
) or the Jest configuration (jest.config.js
), your changes might seem to not take effect as expected. On those times, you might need to clean various caches before starting the packager. To do that, run the script: yarn start:reset
. Other times, you might want to reinstall the NPM packages from scratch and the yarn clean:install
script can be handy.
Although you're not required to use Visual Studio Code for developing gutenberg-mobile, it is the recommended IDE and we have some configuration for it.
When you first open the project in Visual Studio, you will be prompted to install some recommended extensions. This will help with some things like type checking and debugging.
One of the extensions we are using is the React Native Tools. This allows you to run the packager from VSCode or launch the application on iOS or Android. It also adds some debug configurations so you can set breakpoints and debug the application directly from VSCode. Take a look at the extension documentation for more details.
Use the following command to run the test suite:
yarn test
It will run the jest test runner on your tests. The tests are running on the desktop against Node.js.
To run the tests with debugger support, start it with the following CLI command:
yarn test:debug
Then, open chrome://inspect
in Chrome to attach the debugger (look into the "Remote Target" section). While testing/developing, feel free to springle debugger
statements anywhere in the code that you'd like the debugger to break.
This project is set up to use jest for tests. You can configure whatever testing strategy you like, but jest works out of the box. Create test files in directories called __tests__
or with the .test.js
extension to have the files loaded by jest. See an example test here. The jest documentation is also a wonderful resource, as is the React Native testing tutorial.
This repository uses Appium to run UI tests. The tests live in __device-tests__
and are written using Appium to run tests against simulators and real devices. To run these you'll need to check off a few things:
- For now when running the tests you'll need to ensure the metro bundler is not running.
- Appium cli installed and available globally, I'd also recommend using appium doctor to ensure all of Appium's dependencies are good to go. You don't have to worry about starting the server yourself, the tests handle starting the server on port 4723, just be sure that the port is free or feel free to change the port number in the test file.
- For iOS a simulator should automatically launch but for Android you'll need to have an emulator with at least platform version 8.0 fired up and running.
After those are checked off to run the UI tests on iOS run
yarn test:e2e:ios:local
and for android run,
yarn test:e2e:android:local
Note, you might experience problems that seem to be related to the tests starting the Appium server, for example errors that say Connection Refused
, Connection Reset
or The requested environment is not available
. Sorry about that this is still a WIP, you can manually start the Appium server via appium desktop or the cli, then change the port number in the tests while optionally commenting out related code in the beforeAll
and afterAll
block.
For a more detailed outline of the UI tests and how to get started writing one please visit the UI Test documentation and our contributing guide.
The project includes a linter (eslint
) to perform codestyle and static analysis of the code. The configuration used is the same as the one in the Gutenberg project. To perform the check, run:
yarn lint
To have the linter also fix the violations run: yarn lint:fix
.
In parallel to eslint
the project uses Prettier
for codestyling. Run:
yarn prettier
to enforce the style. This will modify the source files to make them conform to the rules.
Flow
is used as a static type checker for JavaScript code. Flow checks JavaScript code for errors through static type annotations. These types allow you to tell Flow how you want your code to work, and Flow will make sure it does work that way. To perform the check run:
yarn flow
You might want to use Visual Studio Code as an editor. The project includes the configuration needed to use the above codestyle and lint tools automatically.
