## Tutorial
You can find a comprehensive tutorial for using this module [on the OpenCage site](https://opencagedata.com/tutorials/geocode-in-nodejs).
## 🔧 Getting started
Signup for a [free-trial API Key](https://opencagedata.com/users/sign_up).
### node
The library uses [dotenv](https://www.npmjs.com/package/dotenv) on node runtime to configure OpenCage Geocoding 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
```
or
```
$ pnpm add opencage-api-client
```
Create a `.env` file with:
```
OPENCAGE_API_KEY=YOUR-OPENCAGE_DATA_API_KEY
```
Here is an example:
```javascript
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:
```html
```
```html
```
2- use it
```javascript
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](./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](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Error) by the `geocode` function. The error object contains the same status object as the [OpenCage API](https://opencagedata.com/api#response).
Assuming the catch statment uses `error` as variable name:
```js
console.log('Error caught:', error.message);
```
will output for a 429:
```bash
Error caught: Too Many Requests
```
and
```js
console.log(JSON.stringify(error, null, 2));
```
will output for a 429:
```json
{
"status": {
"code": 429,
"message": "Too Many Requests"
}
}
```
Check the examples using the Test API key from OpenCage [error handling examples](./examples/apitestkeys.js)
