"**/*.js": "prettier -write -ignore-unknown"ĭone! Our JS code will be properly formatted before our commit is added. husky/pre-commit "npx lint-staged"įinally, let's set up lint-staged in the `package.json file so that it runs Prettier on JS files: // package.json Now, let's add the npx lint-staged command as a new line to the "pre-commit" hook: $ npx husky add.
Gitx hooks install#
Let's install both packages: $ npm install lint-staged prettier -save-dev Then, Prettier will be responsible for the actual formatting and linting (you could definitely go for ESLint instead!). Lint-staged will be used to run checks on staged files (instead of checking the entire project). We will use not one, but two node packages to achieve this task: lint-staged and Prettier. We're big believers that linters boost developer productivity, so let's make sure that any code submitted to the repository is properly linted. If we actually follow the Angular conventions, the commit will go through. The branch's name, main, is accepted, but the commit message isn't, so the commit is aborted: Invalid Git Commit Message To try it out, let's add a commit message that does not follow Angular's guidelines, such as "Add Husky hooks". husky/commit-msg ".git/hooks/commit-msg \$1" $ npm install git-commit-msg-linter -save-devĪnd now we'll add it to Husky (as a "commit-msg" hook this time): $ npx husky add. First we run the usual installation command. Setting it up is similar to the previous example. If you already follow the guidelines from the Angular team, you're in luck: we'll use commit-msg-linter, a package that enforces them. Husky - pre-commit hook exited with code 1 (error) As soon as you add a commit, you will be presented with the following error message: Result: "failed"Įrror Msg: Branch name validate failed please rename your current branch
Let's try it! Start by creating a branch that does not follow this naming convention, like "test". You'll notice that the npx validate-branch-name has been added to Husky's pre-commit file inside Husky's hidden folder (.
husky/pre-commit "npx validate-branch-name" Now, let's add it to Husky as a "pre-commit" hook by running the following command: $ npx husky add. It comes with nice defaults out of the box, that you can further customize with some regex knowledge.įirst, let's install this package: $ npm install validate-branch-name -save-dev There's a little npm package that can help us in this process: validate-branch-name. This hook can be handy when you want to make sure that every branch name follows a specific pattern, such as starting with feature, fix, or release. usr/local/bin:/usr/local/sbin:/usr/bin:/usr/sbin:/bin:/sbin:/Users/brunobrito/.asdf/shimsĪfter saving this file and restarting Tower, everything looks good to go.īack to the command line - time for our first hook! 1. I'm using asdf-nodejs to manage my Node.js versions, so my ist file looks like this: The location will vary depending on your environment. To fix this, we will need to add an ist file in ~/Library/Application Support/3/ and define the PATH environment. Husky - command not found in PATH=/Library/Developer/CommandLineTools/usr/libexec/git-core:/Applications/Tower.app/Contents/Resources/git-flow:/Applications/Tower.app/Contents/Resources/git-lfs:/usr/local/bin:/usr/local/sbin:/usr/bin:/usr/sbin:/bin:/sbinĪs described here, this happens because GUI apps don't know the environment set up by your shell. Husky - pre-commit hook exited with code 127 (error) husky/pre-commit: line 4: npx: command not found When you have some Git hooks configured in Husky, you will get an error message in Tower when you attempt to add a commit. That's it! Husky is ready to be used on the command line, but we should also make sure everything is set up nicely in Tower, our Git client, as well. Once installed, you will also need to run this command to enable Git hooks: $ npx husky installįinally, let's edit the package.json file so that it automatically runs this last command after installation: // package.json Like any node package, you can install Husky with npm or yarn: $ npm install husky -save-dev
Let's get started! Getting Started with Husky
