A complete Lerna-Electron-React-TypeScript project boilerplate.

When developing electron applications, perhaps you want to separate main process codes and renderer process codes into isolated parallel packages, and perhaps even more structure-independent packages which are actually linked while using. For example:

root
├── app-main          # main process source codes
├── app-renderer      # renderer process source codes
└── app-common        # some commonly used codes

That's why in this boilerplate we use Lerna to help managing such a monorepo structure.

This boilerplate is constructed originally from electron-react-boilerplate, but changed greatly to support lerna typescript things. The webpack related develop experience mainly comes from CRA and electron-webpack. It supports:

• monorepo maintained by lerna and yarn workspace mode
• typescript(v4.5+) and babel7 support
• eslint(with ts support), stylelint(with scss support), prettier and commitlint integrated
• smooth and friendly development experience from CRA and electron-webpack.

Just clone this repo and install using yarn:

$ git clone [email protected]:aprilandjan/lerna-electron-react-typescript-boilerplate.git
$ yarn

yarn dev

Check more scripts in package.json scripts field.

vscode debugger supports only inline-source-map. In order to debug main process in vscode debugger, we should:

• change webpack devtool into inline-source-map
• use sourceMapPathOverrides in launch.json to correctly map webpack resources into actual resource url
• alternatively, use webpack devtoolModuleFilenameTemplate to change generated sourcemap data url.

yarn build

Check more scripts in package.json scripts field.

yarn package

Check more scripts in package.json scripts field.

lerna publish --bump 1.1.0

• use execa instead of native child_process
• inject bundle build information, such as commitId, branchName, buildTime, buildMachine, buildPipelineId into process env
• automatically generate changelog files(for different major/minor versions)
• when failed to launching electron, find if existed process is running and print warning (and force kill it in some seconds)
• handle with "failed to fetch extension, trying x more times"
• skip use of yarn to run dev & build
• add timestamp before each output line
• outputs from std error are marked as red
• allow disable console time prefix & suffix
• bug: sometimes press ctrl+c cannot terminate process, for example, when press fn+c allow press X to exit dev process
• the resources of each sub-modules when bundled support
• use rollup to compile & bundle esm modules
• create bundle at the root directory of the workspace
• bug: spawned child process did not exit when terminated in windows
• add unittest for dev scripts
• make execa not spawn process with extra shell processes

• defect: webpack & babel-loader cannot emit declarations, need a solution for this(solution)
• defect: since tsc does not support emit js with resolved alias path, need a solution for this
• fix annoying electron main process error outputs caused by electron-devtools-installer and react-hot possibly
• migrate spectron to playwright
