Chore: Add `husky` to the repo

[coolaj86]

As per https://github.com/typicode/husky#install:

1. Add husky (no transitive dependencies):

   npm install --save-dev husky
   

2. Add a new prepare to package.json.scripts:

   npm set-script prepare "husky install"
   npm run prepare
   

3. Create the new pre-commit script

   npx husky add .husky/pre-commit "npm run fmt"
   npx husky add .husky/pre-commit "npm run lint"
   git add .husky/pre-commit

Hi @coolaj86 , I'm trying to raise a PR, but when I try to commit my code it says fmt script is missing in package.json, could I get help on that ?

[coolaj86]

Those commands need to be set / updated.

npm set-script fmt "npm run prettier; npm run shfmt"
npm set-script jshint "npx [email protected] -c ./.jshintrc */*.js"
npm set-script shellcheck "shellcheck -s sh --exclude=SC2154,SC2034 -- */*.sh */*/*.sh"
npm set-script lint "npm run jshint; npm run shellcheck"
