npm install -g skpm

The npm command-line tool is bundled with Node.js. If you have it installed, then you already have npm too. If not, go download Node.js.

• Installing a plugin
• Uninstalling a plugin

I'm a plugin developer

• Scaffold the architecture of a new plugin
• Build the plugin
• Symlinking the local plugin to the sketch plugins folder
• Publish the plugin on the registry

To install a sketch plugin:

skpm install name-of-the-plugin

To uninstall a sketch plugin:

skpm uninstall name-of-the-plugin

To search for a sketch plugin:

skpm search query

To interactively create the architecture to start developing a new plugin (see the sketch documentation for more information):

skpm init

This will create:

• a package.json file
• a src folder with:
  • a manifest.json file
  • a command.js file for an example of command
• a .gitignore file if non-existent

The package.json must contain 3 specific fields:

• skpm.main: pointing to your .sketchplugin
• skpm.manifest: pointing to your manifest.json (src/manifest.json by default)
• repository: pointing to your github repository

To transpile the JavaScript to CocoaScript and copy the manifest.json to the .sketchplugin:

skpm build

To watch for changes:

skpm build --watch

Additionally, some fields from the package.json will be set in the manifest.json (if not present):

• version
• name
• description
• homepage
• appcast

skpm link path-to-local-plugin

It will also ask you if you want to disable the caching mechanism and force Sketch to always reload a Plugin’s code from disk (recommended when developing).

To publish a new version of the plugin to the registry:

skpm publish <newversion> | major | minor | patch | premajor | preminor | prepatch | prerelease

The exact order of execution is as follows:

• Run the preversion script
• Bump version in package.json as requested (patch, minor, major, etc).
• Run the version script
• Commit and tag
• Run the postversion script.
• Run the build script
• Zip the folder specified in the main field
• Create a draft release on GitHub
• Upload the zip to GitHub
• Publish the release
• Remove the zip
• Check the sketchplugins/plugin-directory repo to see if the plugin is already there. If not, open a PR to add it.
