# RW API microservice utility for Nodejs applications
[](https://travis-ci.com/resource-watch/rw-api-microservice-node)
[](https://codeclimate.com/github/resource-watch/rw-api-microservice-node/test_coverage)
Library to register and integrate microservices in the [RW API](https://api.resourcewatch.org/).
Supports [Koa](https://koajs.com/) 2.x and 1.x frameworks.
## Requirements
- Nodejs v11 or greater
## Install
Using NPM:
````
npm install --save rw-api-microservice-node
````
Using Yarn:
````
yarn add rw-api-microservice-node
````
## Use in microservice
In the `listen` callback of your Koa application, add the following code snippet:
```javascript
const Koa = require('koa');
const RWAPIMicroservice = require('rw-api-microservice-node')
const app = new Koa();
app.use(RWAPIMicroservice.bootstrap({
logger: logger,
microserviceToken: '<your microservice token>',
gatewayURL: '<your gateway URL>',
fasltyEnabled: true,
fastlyServiceId: '<your Fastly service id>',
fastlyAPIKey: '<your Fastly API key>',
awsRegion: '<your AWS region>',
awsCloudWatchLogStreamName: '<your AWS CloudWatch log stream name>',
}))
// Make sure you add your auth-depending routes *after* bootstraping this module
const server = app.listen(process.env.PORT, () => {
logger.info('Server started!');
});
```
## Configuration
These are the values you'll need to provide when using this library:
See [this link](https://docs.fastly.com/en/guides/finding-and-managing-your-account-info) for details on how to get
Fastly credentials.
| Argument name | Type | Description | Required? | Default value |
|--------------------------------|---------------|-----------------------------------------------------------------------------------------------------------------------------------------------------|-------------------|------------------|
| logger | Object | A `bunyan` logger object, for logging purposes | yes | |
| gatewayURL | string | The URL of the API as a whole, where all other services will be reachable | yes | |
| microserviceToken | string | JWT token to use on calls to other services | yes | |
| skipAPIKeyRequirementEndpoints | Array<Object> | List of object containing a `method` and `pathRegex`. Incoming requests that match one of the elements on the list will bypass API Key requirement. | no | |
| fastlyEnabled | boolean | If set to `true`, the [Fastly](https://www.fastly.com/) integration will be enabled | yes | |
| fastlyServiceId | string | Access credentials to the [Fastly](https://www.fastly.com/) API | if Fastly enabled | |
| fastlyAPIKey | string | Access credentials to the [Fastly](https://www.fastly.com/) API | if Fastly enabled | |
| requireAPIKey | boolean | If API keys are required. If set to true, requests with no API key automatically get a HTTP 403 response. | no | true |
| awsCloudWatchLoggingEnabled | boolean | If API key usage should be logged to AWS CloudWatch. | no | true |
| awsRegion | string | Which AWS region to use when logging requests to AWS CloudWatch. | yes | |
| awsCloudWatchLogGroupName | string | Which CloudWatch Log Group name to use when logging requests to AWS CloudWatch. | no | 'api-keys-usage' |
| awsCloudWatchLogStreamName | string | Which CloudWatch Log Stream name to use when logging requests to AWS CloudWatch. | yes | |
