Dev server not starting with react plugin

[iamravisingh]

Hello Everyone,

I am trying to migrate from CRA to rspack. I followed the amazing docs to use rsbuild for my use case. However, currently stuck on some local error for react plugin attached as a screenshot. Initially it did worked, later with some changes it started failing with attached error. I have also added the version of rsbuild which I am currently using.

Additionally, I have also observed, plugin-react is yelling with ts error Rspack.SwcLoaderTransformConfig['react'] is failing with below error. Does this somewhere connected?

I might be missing something small, any help is appreciated. Please find the below config file and package details.

npmPackages:
   @rsbuild/core: ^1.0.0-alpha.5
   @rsbuild/plugin-eslint: ^1.0.0
   @rsbuild/plugin-react: ^1.0.0-alpha.5
   @rsbuild/plugin-sass: ^1.0.0-alpha.5

rsbuild.config.ts

/* eslint-disable import/no-extraneous-dependencies */
import { defineConfig } from "@rsbuild/core";
import { pluginReact } from "@rsbuild/plugin-react";
import { pluginEslint } from "@rsbuild/plugin-eslint";
import { pluginSass } from '@rsbuild/plugin-sass';


export default defineConfig({
    plugins: [
        pluginReact({
            enableProfiler: true,
        }),
        pluginEslint(),
        pluginSass()
    ],
    dev: {
        client:{
            port: "3000"
        },
        progressBar: {
            id: "Build progress"
        }
    }
});

Hey, according to the error message you provided, I suspect that you have installed an unexpected version of rsbuild (rsbuild 1.0.0 is a deprecated version 😭 ), maybe you should lock rsbuild to 1.0.0-alpha.5.

npmPackages:
-   @rsbuild/core: ^1.0.0-alpha.5
-   @rsbuild/plugin-eslint: ^1.0.0
-   @rsbuild/plugin-react: ^1.0.0-alpha.5
-   @rsbuild/plugin-sass: ^1.0.0-alpha.5
+   @rsbuild/core: 1.0.0-alpha.5
+   @rsbuild/plugin-eslint: 1.0.0-alpha.5
+   @rsbuild/plugin-react: 1.0.0-alpha.5
+   @rsbuild/plugin-sass: 1.0.0-alpha.5

Ah! Damn, I knew I was missing something small. @9aoy thanks for the quick response.
I have locked the version for the rsbuild packages and things are working fine.
