spec-change

spec-change

Computes specs to re-run when files change

Based on the import and require directives.

const { getDependentFiles } = require('spec-change')
const deps = getDependentFiles([
  'path/to/spec1.js',
  'path/to/spec2.js',
  ...
], 'path/to/common/directory')

The output will be an object with all files (the initial plus all files they import or require). Each key will be a relative filename to the directory. The values will be arrays, with relative filenames of files dependent on the key file.

{
  // input files at least dependent on selves
  'path/to/spec1.js': ['path/to/spec1.js'],
  'path/to/spec2.js': ['path/to/spec2.js'],
  // the spec2 imports something from utils
  'path/to/utils.js': ['path/to/spec2.js'],
  ...
}
