This package contains a major mode for Yarn-generated yarn.lock files.

M-x package-install RET yarn-mode RET

That should do it. If it doesn't highlight the files, try adding (require 'yarn-mode) in your init.el file.

Copy yarn-mode.el to your load path and then:

(require 'yarn-mode)

Yes. It's that simple.

• Font locking in the buffer
• Automatic read-only when reading the buffer

If you'd like to manage Yarn through emacs, you might want to check yarn.el also.

This package was heavily influenced by

• YAML mode
• Nginx mode
• Xah Lee guide
