Extensions libraries

This mono-repository contains a collection of TypeScript libraries which are used in AdGuard browser extensions and other projects.

Packages

The following packages are available in this repository:

Detailed information on each package is available in the ./packages directory.

Development

Prerequisites

Ensure that the following software is installed on your computer:

• Node.js, we recommend using the latest LTS version via nvm
• pnpm for package management
• Git for version control

[!NOTE]
For development, our team uses macOS and Linux. It may be possible that some commands not work on Windows, so if you are using Windows, we recommend using WSL or a virtual machine.

Environment Setup

Install dependencies with pnpm: pnpm install.

[!NOTE]
pnpm currently doesn't support installing per package dev dependencies (see https://github.com/pnpm/pnpm/issues/6300).

[!NOTE]
If you want to use another linked packages in monorepo workspace, link it in root folder.

This repository uses pnpm workspaces and Lerna to manage multiple packages in a single repository.

Development Commands

• Runs tests in all packages: npx lerna run test
• Lint all packages: pnpm lint
• Remove node_modules from all packages and root package: pnpm clean
• Builds the packages in the current repo: npx lerna run build
• Builds a specific package: npx lerna run build --scope=<package-name>
  • For example, to build the tswebextension package: npx lerna run build --scope=@adguard/tswebextension. This command also builds @adguard/tsurlfilter first as it is required for @adguard/tswebextension.

[!NOTE] You can find Lerna commands in the following link: Lerna Commands.

Linking packages from this monorepo to another projects

pnpm has a nested structure for packages, which is not compatible with the classic yarn, because yarn using a flat structure, but you can force pnpm to use a flat structure too by setting the --shamefully-hoist flag.

For example, if you want to link the tswebextension package from this monorepo to the browser extension project which are using yarn, you can follow these steps:

1. Install packages in this monorepo with pnpm install --shamefully-hoist.
2. Go to the tswebextension package directory: cd packages/tswebextension, and run yarn link.
3. Go to the browser extension project directory: cd /path/to/browser-extension, and run yarn link @adguard/tswebextension. This way, the browser extension project will use the linked package from this monorepo, instead of the published one from the npm registry.

If the other project are using pnpm, you can use pnpm link to connect the packages locally. For more details, please check the pnpm documentation.

Sample extensions

Source code of sample extensions can be found in ./packages/examples directory.

You can build them using the following commands:

• MV2 sample extension: npx lerna run build --scope tswebextension-mv2
• MV3 sample extension: npx lerna run build --scope tswebextension-mv3
• AdGuard API example: npx lerna run build --scope adguard-api-example

To test if this extension works correctly you can use the following test pages:

Test pages:

• Simple rules test
• Script rules test

VSCode Workspace

If you're using Visual Studio Code for development, it may be easier to work with the monorepo if you use the workspace functionality. To do this, create a tsurlfilter.code-workspace file in the monorepo root directory.

jest.runMode and jest.enable would be useful to those that use Jest plugin.
