This repository demonstrates how to develop a snap with TypeScript. For detailed instructions, see the MetaMask documentation.
MetaMask Snaps is a system that allows anyone to safely expand the capabilities of MetaMask. A snap is a program that we run in an isolated environment that can customize the wallet experience.
To interact with (your) Snaps, you will need to install MetaMask Flask, a canary distribution for developers that provides access to upcoming features.
Clone the template-snap repository using this template and set up the development environment:
yarn install && yarn start
This repository contains GitHub Actions that you may find useful, see
.github/workflows
and Releasing & Publishing
below for more information.
If you clone or create this repository outside the MetaMask GitHub organization,
you probably want to run ./scripts/cleanup.sh
to remove some files that will
not work properly outside the MetaMask GitHub organization.
If you don't wish to use any of the existing GitHub actions in this repository,
simply delete the .github/workflows
directory.
Run yarn test
to run the tests once.
Run yarn lint
to run the linter, or run yarn lint:fix
to run the linter and
fix any automatically fixable issues.
Scripts are disabled by default for security reasons. If you need to use NPM
packages with scripts, you can run yarn allow-scripts auto
, and enable the
script in the lavamoat.allowScripts
section of package.json
.
See the documentation for @lavamoat/allow-scripts for more information.
