@connectrpc/connect-web

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

@connectrpc/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 { createClient } from "@connectrpc/connect";
+ import { createConnectTransport } from "@connectrpc/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 = createClient(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 { createClient } from "@connectrpc/connect";
+ import { createGrpcWebTransport } from "@connectrpc/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 = createClient(ElizaService, transport);
const { sentence } = await client.say({ sentence: "I feel happy." });
console.log(sentence) // you said: I feel happy.

grpc-web

grpc-web is a JavaScript implementation of gRPC for web clients. It provides similar functionality to @connectrpc/connect-web, allowing web applications to communicate with gRPC services. However, grpc-web is more established and widely used, whereas @connectrpc/connect-web may offer a more modern or streamlined API.

grpc

grpc is the official Node.js library for gRPC, primarily used for server-side applications. While it supports full gRPC functionality, it does not directly support gRPC-web, which is specifically designed for web clients. @connectrpc/connect-web is tailored for web environments, making it more suitable for client-side use.
