Running example

Example


Requirements

  • Must have at least one of the before mentioned markup items;
  • You should have json-summary as a coverageReporter in your tests configuration;
  • For example, if you are using Jest, configuration should either be within package.json or inside your jest config file i.e. jest.config.js or jestconfig.json as shown below:
  "coverageReporters": ["json-summary"]

Installation

  npm i -D istanbul-badges-readme

Usage

  • Simply run it from the CLI as follows:
  npm run istanbul-badges-readme
  • Custom coverage directory? Use --coverageDir argument:
  npm run istanbul-badges-readme --coverageDir="./my-custom-coverage-directory"
  • Want it without logging? Try silent mode with --silent argument:
  npm run istanbul-badges-readme --silent
  • Or add it to your package.json scripts as follows:
"scripts": {
  "make-badges": "istanbul-badges-readme",
}

Usage as a part of your githooks

  • If you want to have this run on the pre-commit hook and update the commit in place, just install husky and add the pre-commit script to your package.json.
  1. Install Husky.
  npm install -D husky
  1. Add your pre-commit script:
  "husky": {
    "hooks": {
      "pre-commit": "npm run test && istanbul-badges-readme && git add 'README.md'"
    }
  }
  1. Git Commit and Push. Just use your workflow as usual. If your tests fail, no commit. If they pass, update the README.md and add the file to the commit. Nice!
