Pull Request Overview
This PR enhances environment variable injection by tracking which keys are actually written to process.env and reflecting that in the log output.
- Return a
populatedobject frompopulateto record written keys - Use
populatedinstead ofparsedAllto compute keys count for logging - Update the log message formatting and add assignments to
populatedin both override and default branches
Comments suppressed due to low confidence (4)
lib/main.js:341
- Add unit tests for
populateto verify the returnedpopulatedobject contains exactly the keys that were written toprocess.env, including both override and default branches.
const populated = {}
lib/main.js:338
- Update the function’s documentation or add a JSDoc block to describe the new return value (
populated) and its behavior, so consumers know about the API change.
function populate (processEnv, parsed, options = {}) {
lib/main.js:370
- Introducing a return value in
populateis an API change; consider whether this requires a major version bump or an explicit note in the changelog to avoid breaking downstream users.
return populated
lib/main.js:277
- [nitpick] The bracketed '[tip]' prefix differs from the existing emoji style in logs; consider aligning log message formatting with the project’s established conventions.
_log(`injecting env (${keysCount}) from ${shortPaths.join(',')} – [tip] encrypt with dotenvx: https://dotenvx.com`)
