serialize-closures
This package is a runtime library for that allows for arbitrary object graphs to be serialized, including variable-capturing functions. Be aware that only functions whose code has first been processed by ts-closure-transform are eligible for serialization.
IMPORTANT starting from version 1.0 this library is ESM. If you want to use serialize-closures in a CJS-based project, you will probably want to use a version < 1.0.
serialize-closures defines the serialize and deserialize functions. These should work for any object graph as long as all source code has first been processed by ts-closure-transform.
Here's some example usage of serialize and deserialize:
import { serialize, deserialize } from 'serialize-closures';
// Just about anything can be serialized by calling `serialize`.
let capturedVariable = 5;
let serialized = serialize(() => capturedVariable);
// Serialized representations can be stringified and parsed.
let text = JSON.stringify(serialized);
let parsed = JSON.parse(text);
// Serialized representations can be deserialized by calling `deserialize`.
console.log(deserialize(serialized)()); // Prints '5'.If you want to attach some data to an object that don't want to see serialized, then you can assign that property a name that starts with two underscores. The serializer will ignore those when serializing.
deserialize(serialize({ __dont_include_this: 10 })); // Produces '{ }'.
