export default createConfig({
  packageJsonPath: '..',
  validateFn: declareValidation({
    'yargs': {

      validUntil: new Date(),

config API

createConfig

Wrapper for config object for better IDE support. Example of usage you can see above. Arguments:

  • packageJsonPath - path to package.json file. Default: process.cwd()
  • validateFn - function that will be called for each dependency. Please see createValidationFn for more details.
declareValidation

Helper function to declare validation rules for specific package. Example of usage you can see above. Arguments:

  • key of the object - package name
  • value:
    • minimalNodeVersion - minimal node version for which package is deprecated.
    • message - message that will be shown if package is deprecated.
    • validUntil [Optional] - date until package is valid. If date is expired, package will be marked as deprecated.
createValidateFn

Helper function to create validate function for specific package. Should return validDep or invalidDep. Example of usage you can see in declareValidation file

Tips

How to hide specific package from the report

You can use --config option to declare config file with validUntil for specific package. For example:

// config.cleanup-deps.mjs
import { createConfig, declareValidation } from './index.js';

export default createConfig({
  packageJsonPath: '..',
  validateFn: declareValidation({
    'object.assign': {
      minimalNodeVersion: '0.0.0',
      message: 'test',
      validUntil: new Date('2030-01-01'),
    }
  })
})

After '2030-01-01' date, the package object.assign will be shown in the report. Before that the package will be undeprecated dep.

Limitations

  • Only dependencies and devDependencies sections are supported.
  • Only node runtime are supported. The browser runtime will be supported in the future.
  • We have a small list of packages in our deprecation list.
