serialize-error
Advanced tools
The serialize-error npm package is used to serialize error objects into plain objects, retaining as much information as possible. It can be useful for logging errors or sending them over the network, as standard Error objects may not be properly serialized by default JSON.stringify.
Serialize an Error object
This feature allows you to serialize a standard Error object into a JSON-friendly format, including properties like name, message, and stack.
{"error": {"name": "Error", "message": "An error occurred!", "stack": "Error: An error occurred!\n at Object.<anonymous> (/path/to/file.js:2:15)\n at Module._compile (internal/modules/cjs/loader.js:1137:30)\n at Object.Module._extensions..js (internal/modules/cjs/loader.js:1157:10)\n at Module.load (internal/modules/cjs/loader.js:985:32)\n at Function.Module._load (internal/modules/cjs/loader.js:878:14)\n at Function.executeUserEntryPoint [as runMain] (internal/modules/run_main.js:71:12)\n at internal/main/run_main_module.js:17:47"}}
Serialize custom error properties
This feature allows you to serialize Error objects that have custom properties beyond the standard Error properties.
{"error": {"name": "CustomError", "message": "Something custom happened!", "customProperty": "Custom value", "stack": "CustomError: Something custom happened!\n at Object.<anonymous> (/path/to/file.js:2:15)\n at Module._compile (internal/modules/cjs/loader.js:1137:30)\n at Object.Module._extensions..js (internal/modules/cjs/loader.js:1157:10)\n at Module.load (internal/modules/cjs/loader.js:985:32)\n at Function.Module._load (internal/modules/cjs/loader.js:878:14)\n at Function.executeUserEntryPoint [as runMain] (internal/modules/run_main.js:71:12)\n at internal/main/run_main_module.js:17:47"}}
This package is similar to serialize-error in that it provides a way to serialize error objects to JSON. It may differ in the specific implementation or additional options provided for serialization.
While not exclusively for error objects, serialize-javascript allows for the serialization of JavaScript expressions, including errors. It can serialize functions, regexes, and dates, in addition to errors, which may make it more versatile in some scenarios compared to serialize-error.
Serialize an error into a plain object
Useful if you for example need to JSON.stringify()
or process.send()
the error.
$ npm install serialize-error
const serializeError = require('serialize-error');
const error = new Error('🦄');
console.log(error);
//=> [Error: 🦄]
console.log(serializeError(error));
//=> {name: 'Error', message: '🦄', stack: 'Error: 🦄\n at Object.<anonymous> …'}
