opencage-api-client

This repository is an OpenCage Data API client for JavaScript and node.

CircleCI (all branches) npm codecov Maintainability stability status security status FOSSA Status

Getting started

Signup for a free API Key.

node

The library uses dotenv on node runtime to configure OpenCage Data API key. But using key as an input parameter is always a possiblity.

First install the library with npm or yarn:

$ npm i --save opencage-api-client

or

$ yarn add opencage-api-client

Create a .env file with:

OPENCAGE_API_KEY=YOUR-OPENCAGE_DATA_API_KEY

Here is an example:

const opencage = require('opencage-api-client');

opencage
  .geocode({ q: 'lyon' })
  .then((data) => {
    console.log(JSON.stringify(data));
  })
  .catch((error) => {
    console.log('error', error.message);
  });

browser

The browser version is built over the node one, obviously without the dotenv feature.

The library is available with unkpg CDN : https://unpkg.com/opencage-api-client

1- include the library:

<!-- latest version -->
<script src="https://unpkg.com/opencage-api-client"></script>
<!-- specific version -->
<script src="https://unpkg.com/opencage-api-client@0.10.0/dist/opencage-api.min.js"></script>

2- use it

opencage
  .geocode({ q: 'lyon', key: 'YOUR-API-KEY' })
  .then((data) => {
    console.log(JSON.stringify(data));
  })
  .catch((error) => {
    console.log('Error caught:', error.message);
  });

3- others Examples

Found some examples in the examples folder.

API

geocode

Parameter Type Optional? Description
q String mandatory the query string to be geocoded: a placename, address or coordinates as lat,long
key String optional the key can be omitted when using a proxyURL or when using node with a dedicated environment variable
proxyURL String optional The proxy URL parameter (useful to hide your API key)

Error handling

API can return errors like invalid key, to many requests, daily quota exceeded, etc. Thoses errors are thrown as Javascript Error by the geocode function. The error object contains the same status object as the OpenCage API.

Assuming the catch statment uses error as variable name:

console.log('Error caught:', error.message);

will output for a 429:

Error caught: Too Many Requests

and

console.log(JSON.stringify(error, null, 2));

will output for a 429:

{
  "status": {
    "code": 429,
    "message": "Too Many Requests"
  }
}

Check the examples using the Test API key from Opencage error handling examples
