Overview

This repository employs a monorepo setup with pnpm workspaces, and hosts a number of associated but separated packages.

In the packages directory:

• bundler-vite: The VuePress bundler package with vite. Use vite to dev and build VuePress app that generated by @vuepress/core.
• bundler-webpack: The VuePress bundler package with webpack. Use webpack to dev and build VuePress app that generated by @vuepress/core.
• cli: The VuePress command line interface (CLI) package. It will resolve user config file, and create VuePress app with @vuepress/core, then execute corresponding command.
• client: The VuePress client package. Provides the client entry, and exports types and composable utils that can be used in client side development.
• core: The VuePress core. Provides pure Node API to generate VuePress app, including page handling, plugin system and data preparation.
• markdown: The VuePress markdown package. Use markdown-it as the markdown parser and integrate some plugins to be used in VuePress.
• shared: Utilities that shared between node side and client side.
• utils: Utilities that should only be used in node side.

Here are some wrapper packages that use the above packages:

• vuepress: A wrapper the above packages, and provides vuepress command line tool. Users need to choose and install bundler and theme by themselves.

Development Setup

Pre-requirement:

• Node.js version 18.16.0+
• pnpm version 8+

Clone the repo, and install dependencies:

pnpm install

Build source code:

pnpm build

Tools

• TypeScript as the development language
• ESLint + Prettier for code linting and formatting
• Vitest for unit testing
• Playwright for end-to-end testing

Scripts

pnpm build

The build script uses tsup to compile TypeScript source files to JavaScript dist files.

You may need to run this script first after your clone this repository, because the dist files are ignored by .gitignore.

pnpm clean

The clean script runs clean script in all packages, cleaning all the dist files and caches. In other words, it will remove all the files that generated by build scripts.

It's used before you want to re-build source files from a clean / initial state.

pnpm format

The format script uses Prettier to format all source files.

pnpm lint

The lint script uses ESLint to check all source files.

pnpm test

The test script uses Vitest to run unit testings, and uses Playwright to run end-to-end testings.

End-to-end Testing

All end-to-end (e2e) tests are located in e2e directory.

You can also make use of the e2e site to test features during development. The source code of the e2e site is located in e2e/docs.

To run e2e tests, you need to change the working directory to e2e first:

cd e2e

Using E2E Site

The e2e site is a normal VuePress setup, you can run dev and build commands in it:

# start dev server
pnpm docs:dev
# build and start preview server
pnpm docs:build
pnpm docs:serve

Run E2E Tests

# run e2e tests in dev mode
pnpm e2e:dev
# run e2e tests in build mode
pnpm e2e:build
