Package Exports

borsh
borsh/lib/index.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (borsh) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

Borsh JS

Borsh JS is an implementation of the Borsh binary serialization format for JavaScript and TypeScript projects.

Borsh stands for Binary Object Representation Serializer for Hashing. It is meant to be used in security-critical projects as it prioritizes consistency, safety, speed, and comes with a strict specification.

Examples

Serializing an object

const value = new Test({ x: 255, y: 20, z: '123', q: [1, 2, 3] });
const schema = new Map([[Test, { kind: 'struct', fields: [['x', 'u8'], ['y', 'u64'], ['z', 'string'], ['q', [3]]] }]]);
const buffer = borsh.serialize(schema, value);

Deserializing an object

const newValue = borsh.deserialize(schema, Test, buffer);
