## Description
npm install @truestamp/canonifyA tiny zero-dependency JSON canonicalization library written in Typescript that supports ES Modules, IIFE, and CommonJS loaders and runs in Deno, Node.js, and modern browsers.
Canonicalization of JavaScript/TypeScript data structures to a standard and deterministically ordered output can be very useful for hashing and signing complex nested structures where the ordering is unknown.
This library should fully implements the JSON Canonicalization Scheme (JCS) as documented in RFC8785.
Significant testing was done to ensure the library stays true to JSON.stringify() single argument behaviors.
Here are some simple usage examples.
There are working code examples for Deno, Node.js, and the Web in the /examples directory. Take a look at the examples/README.md for usage instructions.
#### Setup Node.js
In your NPM project directory.
``bash`
npm install --save @truestamp/canonify
Require the @truestamp/canonify CommonJS module in your project.
#### Node.js Example
`js
const { canonify } = require('@truestamp/canonify')
const example = {
big: BigInt(42).toString(),
f: false,
fun: () => {},
n: null,
num: 42,
s: 'string',
sym: Symbol('hello'),
t: true,
u: undefined,
a: [
undefined,
null,
true,
false,
'foo',
42,
BigInt(42).toString(),
Symbol('hello'),
() => {},
],
}
console.log(canonify(example))
`
Deno is a simple, modern and secure runtime for JavaScript
and TypeScript that uses V8 and is built in Rust.
#### Setup Deno
Recent versions of canonify are published to the official Deno third party modules CDN.
#### Deno Example
`typescriptcanonify
// IMPORTANT : use the current release version of @v1.1.1
// in the module URL. Replace with the latest version.
// Versions are tied to GitHub release tags.
import { canonify } from 'https://deno.land/x/canonify@v2.0.2/mod.ts'
const example = {
big: BigInt(42).toString(),
f: false,
fun: () => {},
n: null,
num: 42,
s: 'string',
sym: Symbol('hello'),
t: true,
u: undefined,
a: [
undefined,
null,
true,
false,
'foo',
42,
BigInt(42).toString(),
Symbol('hello'),
() => {},
],
}
console.log(canonify(example))

This library aims to maintain 100% code test coverage and it passes 100% of the test vectors provided by the RFC8785 testdata vectors.
This should help ensure that its output is consistent with other compliant libraries on other runtimes.
Much of the code is ported to TypeScript from, and was based on, the following excellent examples:
- https://github.com/cyberphone/json-canonicalization
- erdtman/canonicalize
