Run Linting, Tests and Prettier in git Hooks with Husky

Share this video with your friends

With the ability to run unit tests, automatic code formatting and linting, we should avoid ever committing code that does not adhere to our project standards or breaks our tests. In this lesson, we'll install and configure the Husky npm package and enforce these checks before a git commit is allowed.

In the test file from the Transcript says 'if'. if('Fails', () => { expect(true).toBe(false) }) Salute.

Due to I am using google prettier setup eslint was overriding the prettier output hence I was unable to commit. The solution was to use this package

npm i -D eslint-config-prettier

Then, add eslint-config-prettier to the "extends" array in your .eslintrc file. Make sure to put it last, so it gets the chance to override other configs.

{ "extends": [ "some-other-config-you-use", "prettier" ] }

If I do not use my script , the pre-commit hook works "pre-commit": "eslint ./"
