serializeError usage in Flyde
I found the following import in flyde/core/src/remote-debugger/utils.ts.
import { serializeError } from "serialize-error";
and this function is used as shown below:
export const toString = (v: any) => {
const type = typeof v;
switch (type) {
case "object":
if (v instanceof Error) {
return JSON.stringify(serializeError(v));
}
try {
return JSON.stringify(v).substr(0, STRING_LIMIT);
} catch (e) {
return `Object (cannot stringify)`;
}
default:
return `${v}`.substr(0, STRING_LIMIT);
}
};
What is Flyde?
Flyde is an open-source visual programming for backend logic that integrates with existing codebases. Flyde bridges the gap between technical and non-technical team members. Product managers, designers, and backend developers can collaborate on the same visual flows.

Serialize/deserialize an error into a plain object
Useful if you for example need to JSON.stringify() or process.send() the error.
Installation
npm install serialize-error
Usage
import {serializeError, deserializeError} from 'serialize-error';
const error = new Error('🦄');
console.log(error);
//=> [Error: 🦄]
const serialized = serializeError(error);
console.log(serialized);
//=> {name: 'Error', message: '🦄', stack: 'Error: 🦄\n at Object.<anonymous> …'}
const deserialized = deserializeError(serialized);
console.log(deserialized);
//=> [Error: 🦄]
