@oada/client

A lightweight client tool for interacting with an OADA-compliant server

Installation

This module is available through npm. To install the module, simply run:

npm install @oada/client

Usage

Connect

import { connect } from '@oada/client';
const connection = await connect({
  domain: 'api.oada.com', // domain of OADA server
  token: 'abc', // token
});

GET

Single GET

const response = await connection.get({
  path: '/bookmarks/test',
  timeout: 1000, // timeout in milliseconds (optional)
});

Recursive GET

const dataTree = {
  bookmarks: {
    _type: 'application/vnd.oada.bookmarks.1+json',
    _rev: 0,
    thing: {
      _type: 'application/json',
      _rev: 0,
      abc: {
        '*': {
          _type: 'application/json',
          _rev: 0,
        },
      },
    },
  },
};
const response = await connection.get({
  path: '/bookmarks/thing',
  tree: dataTree,
  timeout: 1000, // timeout in milliseconds (optional)
});

Watch

A watch request can be issued by sending a watch request as follows.

// Resolves once the watch is established
const { changes } = await connection.watch({
  path: '/bookmarks/test',
  rev: 1, // optional
  timeout: 1000, // timeout in milliseconds (optional)
});

// Async iterator for all changes since the watch was started (or since `rev`)
for await (const change of changes) {
  console.log(change);
}

You can also GET the current state of the resource when establishing a watch as follows.

// Resolves once the watch is established
const { data, changes } = await connection.watch({
  initialMethod: 'get',
  path: '/bookmarks/test',
});

// Current body of the resource
console.dir(data);

// Async iterator for all changes since the watch was started
for await (const change of changes) {
  console.log(change);
}

PUT

Single PUT

const response = await connection.put({
  path: '/bookmarks/test',
  data: { thing: 'abc' },
  contentType: 'application/json',
  timeout: 1000, // timeout in milliseconds (optional)
});

      },
