@mapbox/mapbox-sdk

Build Status

A JS SDK for working with Mapbox APIs.

Works in Node, the browser, and React Native.

As of 6/11/18, the codebase has been rewritten and a new npm package released. The mapbox package is deprecated in favor of the new @mapbox/mapbox-sdk package. Please read the documentation and open issues with questions or problems.

Table of contents

Installation

npm install @mapbox/mapbox-sdk

If you are supporting older browsers, you will need a Promise polyfill. es6-promise is a good one, if you're uncertain.

The documentation below assumes you're using a JS module system. If you aren't, read "Pre-bundled files on unpkg.com".

Usage

There are 3 basic steps to getting an API response:

  1. Create a client.
  2. Create a request.
  3. Send the request.

Creating clients

To create a service client, import the service's factory function from '@mapbox/mapbox-sdk/services/{service}' and provide it with your access token.

The service client exposes methods that create requests.

const mbxStyles = require('@mapbox/mapbox-sdk/services/styles');
const stylesService = mbxStyles({ accessToken: MY_ACCESS_TOKEN });
// stylesService exposes listStyles(), createStyle(), getStyle(), etc.

You can also share one configuration between multiple services. To do that, initialize a base client and then pass that into service factory functions.

const mbxClient = require('@mapbox/mapbox-sdk');
const mbxStyles = require('@mapbox/mapbox-sdk/services/styles');
const mbxTilesets = require('@mapbox/mapbox-sdk/services/tilesets');

const baseClient = mbxClient({ accessToken: MY_ACCESS_TOKEN });
const stylesService = mbxStyles(baseClient);
const tilesetsService = mbxTilesets(baseClient);

Creating and sending requests

To create a request, invoke a method on a service client.

Once you've created a request, send the request with its send method. It will return a Promise that resolves with a MapiResponse.

const mbxClient = require('@mapbox/mapbox-sdk');
const mbxStyles = require('@mapbox/mapbox-sdk/services/styles');
const mbxTilesets = require('@mapbox/mapbox-sdk/services/tilesets');

const baseClient = mbxClient({ accessToken: MY_ACCESS_TOKEN });
const stylesService = mbxStyles(baseClient);
const tilesetsService = mbxTilesets(baseClient);

// Create a style.
stylesService.createStyle({..})
  .send()
  .then(response => {..}, error => {..});

// List tilesets.
tilesetsService.listTilesets()
  .send()
  .then(response => {..}, error => {..})

Overview of requests, responses, and errors

For more details, please read the full classes documentation.

MapiRequest

Service methods return MapiRequest objects.

Typically, you'll create a MapiRequest then send it. send returns a Promise that resolves with a MapiResponse or rejects with a MapiError.

MapiRequests also expose other properties and methods that you might use from time to time. For example:

  • MapiRequest#abort aborts the request.
  • MapiRequest#eachPage executes a callback for each page of a paginated API response.
  • MapiRequest.emitter exposes an event emitter that fires events like downloadProgress and uploadProgress.

For more details, please read the full MapiRequest documentation.

// Create a request and send it.
stylesService.createStyle({..})
  .send()
  .then(response => {..}, error => {..});

// Abort a request.
const req = tilesetsService.listTilesets();
req.send().then(response => {..}, error => {
  // Because the request is aborted, an error will be thrown that we can
  // catch and handle.
});
req.abort();

// Paginate through a response.
tilesetsService.listTilesets().eachPage((error, response, next) => {
  // Do something with the page, then call next() to send the request
  // for the next page.

  // You can check whether there will be a next page using
  // MapiResponse#hasNextPage, if you want to do something
  // different on the last page.
  if (!response.hasNextPage()) {..}
});

// Listen for uploadProgress events.
const req = stylesService.createStyleIcon({..});
req.on('uploadProgress', event => {
  // Do something with the progress event information.
});
req.send().then(response => {..}, error => {..});

MapiResponse

When you send a MapiRequest, the returned Promise resolves with a MapiResponse.

Typically, you'll use MapiResponse.body to access the parsed API response.

MapiResponses also expose other properties and methods. For example:

  • MapiResponse#hasNextPage indicates if there is another page of results.
  • If there is another page, MapiResponse#nextPage creates a MapiRequest that you can send to get that next page.
  • MapiResponse.headers exposes the parsed HTTP headers from the API response.

For more details, please read the full MapiResponse documentation.

// Read a response body.
stylesService.getStyle({..})
  .send()
  .then(resp => {
    const style = resp.body;
    // Do something with the style.
  }, err => {..});

// Get the next page of results.
tilesetsService.listTilesets()
  .send()
  .then(resp => {
    if (resp.hasNextPage()) {
      const nextPageReq = resp.nextPage();
      nextPageReq.send().then(..);
    }
  }, err => {..});

// Check the headers.
tilesetsService.listTilesets()
  .send()
  .then(resp => {
    console.log(resp.headers);
  }, err => {..});

MapiError

If the server responds to your MapiRequest with an error, or if you abort the request, the Promise returned by send will reject with a MapiError.

MapiErrors expose the information you'll need to handle and respond to the error. For example:

  • MapiError.type exposes the type of error, so you'll know if it was an HTTP error from the server or the request was aborted.
  • MapiError.statusCode exposes the status code of HTTP errors.
  • MapiError.body exposes the body of the HTTP response, parsed as JSON if possible.
  • MapiError.message tells you what went wrong.

For more details, please read the full MapiError documentation.

// Check the error.
stylesService.getStyle({..})
  .send()
  .then(response => {..}, error => {
    if (err.type === 'RequestAbortedError') {
      return;
    }
    console.error(error.message);
  });

Services

Please read the full documentation for services.

Pre-bundled files on unpkg.com

If you aren't using a JS module system, you can use a <script> tag referencing pre-bundled files on the CDN unpkg.com.

<script src="https://unpkg.com/@mapbox/mapbox-sdk/umd/mapbox-sdk.js"></script>
<script src="https://unpkg.com/@mapbox/mapbox-sdk/umd/mapbox-sdk.min.js"></script>

These files are a UMD build of the package, exposing a global mapboxSdk function that creates a client, initializes all the services, and attaches those services to the client. Here's how you might use it.

<script src="https://unpkg.com/@mapbox/mapbox-sdk/umd/mapbox-sdk.min.js"></script>
<script>
  var mapboxClient = mapboxSdk({ accessToken: MY_ACCESS_TOKEN });
  mapboxClient.styles.getStyle(..)
    .send()
    .then(..);
  mapboxClient.tilesets.listTilesets(..)
    .send()
    .then(..);
</script>
