Are you overwhelmed by tap 15?

Recently tap bumped to v15! πŸŽ‰

If you are overwhelmed by all your failing workflows, here a snipped to upgrade them all in once!!

I used the old and dirty massive-wax module that I made some time ago to open PRs like this one:

You need to:

Install massive-wax

npm i massive-wax -g
Enter fullscreen mode Exit fullscreen mode

Write a processor

A processor is just a set of functions executed to edit the repository's files.

So create a new tap-15.js file like this (it is sync but async is supported too:

const fs = require('fs')
const path = require('path')

module.exports = function factory (args, logger) {
  return {
    onRepo (repo) {
      const repoPath = path.join(repo.owner, repo.repo)

      const pkjPath = path.join(repoPath, './package.json')
      const pkj = JSON.parse(fs.readFileSync(pkjPath, 'utf-8'))
      pkj.devDependencies.tap = '^15.0.1'
      fs.writeFileSync(pkjPath, JSON.stringify(pkj, null, 2))

      const tapRcPath = path.join(repoPath, '.taprc')
      if (fs.existsSync(tapRcPath)) {
        const tapRc = fs.readFileSync(tapRcPath, 'utf-8')
        let newTapRc = tapRc.replace(/esm: (true|false)\n/i, '')

        if (!pkj.scripts.test.includes('100')) {
          newTapRc += '\ncheck-coverage: false'

        fs.writeFileSync(tapRcPath, newTapRc)
      } else {
        fs.writeFileSync(tapRcPath, 'check-coverage: false\n')
    onFile (file) {
      const fileContent = fs.readFileSync(file, 'utf-8')

      const result = fileContent
        .replace(/tearDown/g, 'teardown')
        .replace(/strictEqual/g, 'equal')
        .replace(/deepEqual/g, 'same')
        .replace(/false\(/g, 'notOk(')
        .replace(/notStrictEqual/g, 'not')
        .replace(/similar/g, 'match')
        .replace(/strictDeepEqual/g, 'strictSame')
        .replace(/is\(/g, 'equal(')
        .replace(/throw\(/g, 'throws(')
        .replace(/like\(/g, 'match(')
        .replace(/contains\(/g, 'has(')
        .replace(/equals\(/g, 'equal(')
        .replace(/true\(/g, 'ok(')
        .replace(/notThrow\(/g, 'doesNotThrow(')

      fs.writeFileSync(file, result)
Enter fullscreen mode Exit fullscreen mode

This script is updated here

Write the repositories list

Create a text file called repo-list with the list of the repositories you want to upgrade:
Enter fullscreen mode Exit fullscreen mode

Run the magic

Now, let's run massive-wax!!

massive-wax upgrade -L -R -m 'test(/|\\).*\.js$' -t 'chore tap 15' -r repo-list -p ./tap-15.js -K <GH-TOKEN>
