# chirpstack-api
|
||
|
|
||
|
ChirpStack gRPC API message and service wrappers for Javascript. Typescript definitions are included.
|
||
|
|
||
|
## Install
|
||
|
|
||
|
With npm:
|
||
|
|
||
|
```sh
|
||
|
npm install @chirpstack/chirpstack-api --save
|
||
|
```
|
||
|
|
||
|
Or with yarn:
|
||
|
|
||
|
```sh
|
||
|
yarn add @chirpstack/chirpstack-api
|
||
|
```
|
||
|
|
||
|
## Usage
|
||
|
|
||
|
All messages, services, constants, etc. are auto-generated from the ChirpStack protobuf definitions. The result is that
|
||
|
this package structure matches that of the protobuf definitions. There is no ES6 index gathering all of the exports, so
|
||
|
full import/require paths should be used. The generated code is all callback based, but can be promisified.
|
||
|
|
||
|
The protobuf definitions can be found here: https://github.com/brocaar/chirpstack-api/tree/master/protobuf
|
||
|
|
||
|
The generated code all depends on the `grpc` package, and for most use cases you will probably need to make use of the
|
||
|
`grpc` package directly as well. This is seen in the example below.
|
||
|
|
||
|
### Example
|
||
|
|
||
|
This example shows how to log in to ChirpStack via the gRPC API and then create a gRPC metadata object containing the
|
||
|
JWT. This metadata could then be passed to any future requests that require authorization.
|
||
|
|
||
|
```javascript
|
||
|
import * as grpc from '@grpc/grpc-js';
|
||
|
|
||
|
import * as internalService from '@chirpstack/chirpstack-api/as/external/api/internal_grpc_pb';
|
||
|
import * as internalMessages from '@chirpstack/chirpstack-api/as/external/api/internal_pb';
|
||
|
|
||
|
// Create the client for the 'internal' service
|
||
|
const internalServiceClient = new internalService.InternalServiceClient(
|
||
|
'localhost:8080',
|
||
|
grpc.credentials.createInsecure()
|
||
|
);
|
||
|
|
||
|
// Create and build the login request message
|
||
|
const loginRequest = new internalMessages.LoginRequest();
|
||
|
|
||
|
loginRequest.setEmail('email');
|
||
|
loginRequest.setPassword('password');
|
||
|
|
||
|
// Send the login request
|
||
|
internalServiceClient.login(loginRequest, (error, response) => {
|
||
|
// Build a gRPC metadata object, setting the authorization key to the JWT we
|
||
|
// got back from logging in.
|
||
|
const metadata = new grpc.Metadata();
|
||
|
metadata.set('authorization', response.getJwt());
|
||
|
|
||
|
// This metadata can now be passed for requests to APIs that require authorization
|
||
|
// e.g.
|
||
|
// deviceServiceClient.create(createDeviceRequest, metadata, callback);
|
||
|
});
|
||
|
```
