Issue
I'm developing a Vue.js web application and I'm using gRPC to assure the communication.
In the frontend, I'm using the web version of gRPC: grpc-web
.
Everything is working just fine; however, when I'm doing an API call in my store, e.g.:
async fetchEcho() {
const echoService = new EchoServiceClient('http://localhost:8080', null, null);
const request = new EchoRequest();
request.setMessage('Hello World!');
const call = echoService.echo(request, {'custom-header-1': 'value1'},
(err: grpcWeb.Error, response: EchoResponse) => {
console.log(response.getMessage());
});
}
How can I use the async/await
pattern when making the call in my Vue file, e.g.:
await fetchEcho();
// ...
And await until the API call has finished to resume my the course of my program?
Thanks!
Solution
I'm using ServicePromiseClient, the example would be something like this:
const echoServiceClient = new EchoServicePromiseClient("http://localhost:8080", null, null);
Then I'm able to create async functions for fetching like this:
async function fetchEcho() {
const echoReq = new EchoRequest();
echoReq.setMessage("Hello world!");
try {
const response = await echoServiceClient.echo(echoReq, {});
return response;
} catch (error) {
console.log(error);
return null;
}
}
