combine-errors
Simple, dependency-free way to combine multiple errors into one.
This is useful for handling multiple asynchronous errors, where you want to catch all the errors and combine them to return just a single error.
Features
error instanceof Error === true
- composable:
error([error([err1, err2]), err3])
- stack and message are combined in a nice way
- array-like object, so you can access the original errors by looping over the error
- If you just have one error, it looks exactly like raw error meaning,
error(err).message === err.message && error(err).stack === err.stack
- zero dependencies
- should work in the browser, though I haven't tested it yet
Installation
npm install combine-errors
