metro-symbolicate

What is metro-symbolicate?

The metro-symbolicate package is part of the Metro bundler (used by React Native) that provides functionality for symbolication. Symbolication is the process of converting machine code addresses back into human-readable source code locations (file names and line numbers). This is particularly useful for interpreting stack traces that are generated from minified or compiled code, making debugging much easier.

What are metro-symbolicate's main functionalities?

Symbolicating stack traces

This feature allows developers to pass a stack trace to the `symbolicateStackTrace` function, which returns a promise that resolves to a symbolicated stack trace. The symbolicated stack trace includes file names, line numbers, and even column numbers when available, making it easier to debug issues.

const symbolicateStackTrace = require('metro-symbolicate').symbolicateStackTrace;
symbolicateStackTrace(stackTrace).then(symbolicated => {
  console.log(symbolicated);
});

Other packages similar to metro-symbolicate

source-map

The source-map package provides functionalities for generating and consuming source maps. While metro-symbolicate is specifically tailored for React Native and integrates with the Metro bundler, source-map is a more general tool that can be used with any JavaScript project to handle source maps for error reporting and debugging.

stacktrace-js

stacktrace-js is a library that provides stack trace parsing and symbolication capabilities. Unlike metro-symbolicate, which is designed to work within the React Native ecosystem, stacktrace-js can be used in any JavaScript environment, including browsers and Node.js, to help developers symbolicate and analyze stack traces.
