firebase-error-mapper v1.0.2

Firebase Error Mapper

Firebase returns error messages that are not very user friendly:

Firebase: Error (auth/network-request-failed).

This library maps the error code to human readable text, as specified in the firebase documentation.

Usage

Create a new FirebaseErrorMessageMapper, and add custom mappings if desired.

const mapper = new FirebaseErrorMessageMapper()
mapper.addMapping("auth/invalid-email", "Please enter a valid email address.");

/* 
  Some code calling Firebase, which throws an error.

  Error {
    message: "Firebase: Error (auth/network-request-failed)."
  }
*/

const mappedErrorMessage = mapper.map(error.message);

// mappedErrorMessage = "A network error has occurred, please try again later."

/* 
  Some other code calling Fireabse, which throws an error.

  Error {
    message: "Firebase: Error (auth/invalid-email)"
  }
*/

const mappedErrorMessage = mapper.map(error.message);

// mappedErrorMessage = "Please enter a valid email address."

TSDX User Guide

Commands

TSDX scaffolds your new library inside /src.

To run TSDX, use:

npm start # or yarn start

This builds to /dist and runs the project in watch mode so any edits you save inside src causes a rebuild to /dist.

To do a one-off build, use npm run build or yarn build.

To run tests, use npm test or yarn test.

Configuration

Code quality is set up for you with prettier, husky, and lint-staged. Adjust the respective fields in package.json accordingly.

Jest

Jest tests are set up to run with npm test or yarn test.

Bundle Analysis

size-limit is set up to calculate the real cost of your library with npm run size and visualize the bundle with npm run analyze.
