TSC to file checklist

When doing a big upgrade on a Typescript project, keeping track of your tsc output can be difficult. To get a list of files in a markdown checklist, you can dump your tsc output to a file, and run this script on that file, and it’ll give you a markdown list of the files you need to go through, one on one.

Notes:

• This excludes any .spec files.
• This is usable with vue-tsc or any other tsc extension

jscopy
1const fs = require('fs')

2const errorsFile = '~/file-of-errors.txt'
3const outputFile = './errorFiles.md'

4const errorsString = fs.readFileSync(errorsFile, 'utf8')
5const errorsArrayExcludeStrings = ['>', 'spec', 'ELIFECYCLE']
6const errorsArray = errorsString.split('\n').filter(error => !error.startsWith(' ') && error !== '' && !errorsArrayExcludeStrings.some(s => error.includes(s)))

7const duplicatedFilesArray = errorsArray.map((error) => {
8  const errorParts = error.split('(')
9  const output = `[ ] ${errorParts[0]}`
10  return output
11})

12const files = [...new Set(duplicatedFilesArray)].sort().sort((a,_b) => a.endsWith('.ts') ? 1 : -1)

13fs.writeFileSync(outputFile, files.join('\n'))

14console.log(`${errorsArray.length} errors across ${files.length} files remaining.
15Output: ${outputFile}`)
