HATEOAS-link-resolver

Small helper library for resolving templated HATEOAS links

Install

Use your favourite package manager

npm i -S hateoas-link-resolver

or

yarn add hateoas-link-resolver

Usage

Just resolve templated links

import { resolve } from 'hateoas-link-resolver';
const templatedLink = 'https://example.org/{id}/sub';
const resolvedLink = resolve(link, {id: '123'});

Use Link repository. Put all link into repository and then retrieve from there and resolve

import { LinkRepository } from 'hateoas-link-resolver';
const links = {
    endpoint1: {
        href: "https://example.org/{id}",
        templated: true
    },
    endpoint2: {
        href: "https://example.org/path/{id}",
        templated: true
    }
};
const repo = new LinkRepository(links);

// resolve
repo.resolve('endpoint1', {id: '123'});

// check existence
repo.has('endpoint1');

// get unresolved link
repo.get('endpoint1');

Limitations

This helper is for rather simple link structures and does not support list of links.
