@bufbuild/connect-web

Connect is a family of libraries for building and consuming APIs on different languages and platforms. @bufbuild/connect brings type-safe APIs with Protobuf to TypeScript.

@bufbuild/connect-web provides the following adapters for web browsers, and any other platform that has the fetch API on board:

createConnectTransport()

Lets your clients running in the web browser talk to a server with the Connect protocol:

import { createPromiseClient } from "@bufbuild/connect";
+ import { createConnectTransport } from "@bufbuild/connect-web";
import { ElizaService } from "./gen/eliza_connect.js";

+ // A transport for clients using the Connect protocol with fetch()
+ const transport = createConnectTransport({
+   baseUrl: "https://demo.connectrpc.com",
+ });

const client = createPromiseClient(ElizaService, transport);
const { sentence } = await client.say({ sentence: "I feel happy." });
console.log(sentence) // you said: I feel happy.

createGrpcWebTransport()

Lets your clients running in the web browser talk to a server with the gRPC-web protocol:

import { createPromiseClient } from "@bufbuild/connect";
+ import { createGrpcWebTransport } from "@bufbuild/connect-web";
import { ElizaService } from "./gen/eliza_connect.js";

+ // A transport for clients using the Connect protocol with fetch()
+ const transport = createGrpcWebTransport({
+   baseUrl: "https://demo.connectrpc.com",
+ });

const client = createPromiseClient(ElizaService, transport);
const { sentence } = await client.say({ sentence: "I feel happy." });
console.log(sentence) // you said: I feel happy.
