— Prettier

This Dev Container Feature installs Prettier and plugins globally using Node.js and npm to run npm install -g prettier. You can also add plugins by specifying a plugins option. This will install all the plugins at once using npm install -g $PLUGINS. You can use prettier-plugin-octocat@1.2.3 full npm specifiers! Just make sure each plugin is separated by a space character, not a comma.

// devcontainer.json

  "ghcr.io/devcontainers-community/features/prettier": {}

// devcontainer.json
"features": {
