githooks for Deno

This is a simple tool for Deno projects that allows you to associate specific deno tasks with specific Git Hooks by extending the native deno.json configuration file or adding a separate one.

It works like this:

1. In your deno.json (or deno.jsonc) file, add a githooks key containing a map of {githook} to {deno task}. For example:

   {
     "tasks": {
       "start": "deno run -A dev.ts",
       "check": "deno fmt --check && deno lint"
     },
     "githooks": {
       "pre-commit": "check"
     }
   }

   You can also create a separate githooks.json, githooks.jsonc, githooks.yaml or githooks.yml file:

   {
     "pre-commit": "check"
   }

   pre-commit: check

   To add autocompletion, you can use our JSON schema. This schema can either be specified in the settings of your code editor or directly in the JSON file:

   {
     "$schema": "https://deno.land/x/githooks/schema.json",
     "pre-commit": "check"
   }

2. In your terminal, run the githooks.ts script. It will automatically create a hook file for each githook in your deno.json file.

   deno run -A -r https://deno.land/x/githooks/githooks.ts

That’s it. Now your Git Hook should call deno task check before every commit.

PROTIP: deco projects come with this extension pre-installed in the dev script. You don’t have to do anything, just add githooks to deno.json and run dev to install the hooks transparently.
