Piggyback

A resource-oriented wrapper over the window.fetch API. Defaults to the JSON content type.

Install

npm install --save piggyback

Usage

Resource Builder

The resource function constructs a complete set of CRUD methods to interact with a conventional HTTP API.

All methods return a promise that resolves the JSON body of the response.

import { resource } from 'piggyback';

const { getTasks, getTaskById, createTask, updateTask, deleteTask } = resource('tasks');

// GET /tasks
getTasks().then((json) => console.log(json));

// GET /tasks/{id}
getTaskById(id).then((json) => console.log(json));

// POST /tasks
createTask(task).then((json) => console.log(json));

// PUT /tasks/{id}
createTask(id, task).then((json) => console.log(json));

// DELETE /tasks/{id}
deleteTask(id);

Sending HTTP Requests

The following methods are provided to interact directly with JSON web APIs:

• sendGet
• sendPost
• sendPut
• sendPatch
• sendDelete

All methods return a promise that resolves to a Response, including the Body mixin of the Fetch API.

import { sendGet, sendPost, sendPut, sendPatch, sendDelete } from 'piggyback';

export default function getTasks() {
  return sendGet('/tasks').then(function(response) {
    return response.json();
  });
}

export default function createTask(task) {
  return sendPost('/tasks', task).then(function(response) {
    return response.json();
  });
}

export default function replaceTask(id, task) {
  return sendPut('/tasks/' + id.toString(), task).then(function(response) {
    return response.json();
  });
}

export default function updateTask(id, task) {
  return sendPatch('/tasks/' + id.toString(), task).then(function(response) {
    return response.json();
  });
}

export default function deleteTask(id) {
  return sendDelete('/tasks/' + id.toString());
}

Notes

• Depends on es6-promise and isomorphic-fetch polyfills (this is handled automatically).
• Browser auth credentials are always sent with the request.
• HTTP error codes result in a JavaScript Error being thrown by default.
• How you handle resolving and rejecting is up to you.

If these defaults aren’t suitable for your use-case, consider using the isomorphic-fetch library directly.
