Code
const webpack = require('webpack'); const WDS = require('webpack-dev-server'); const path = require('path'); const main = require.resolve('./src/index'); const config = { entry: { // new webpack 5 beta 14 features: // "Allow a entry description object for advanced entrypoint configuration" // https://github.com/webpack/webpack/releases/tag/v5.0.0-beta.14 main: { import: [main], filename: 'bundle.js' } }, output: { path: path.join(__dirname, 'dist'), filename: 'bundle.[name].js' }, mode: 'development' }; const port = 38765; const wdsConfig = { hot: true, contentBase: false, port: port, headers: { 'Access-Control-Allow-Origin': '*' } }; // UNCOMMENT THESE LINES FOR SANITY CHECKING THE WEBPACK CONFIGURATION! //////////////////////////////////////////////////////////////////////// // webpack(config, (err, stats) => { // console.log('webpack build OK!'); // }); //////////////////////////////////////////////////////////////////////// // The following line causes invalid configuration: //////////////////////////////////////////////////////////////////////// WDS.addDevServerEntrypoints(config, wdsConfig); //////////////////////////////////////////////////////////////////////// // console.log(config); // console.log(config.entry); const compiler = webpack(config); const devServer = new WDS(compiler, wdsConfig); devServer.listen(port, 'localhost', err => { // noop });Expected Behavior
No Error.
WDS should configure webpack configuration properly.
Actual Behavior
ValidationError: Invalid configuration object. Webpack has been initialized using a configuration object that does not match the API schema. - configuration.entry should be one of these: function | object { <key>: non-empty string | [non-empty string, ...] (should not have fewer than 1 item, should not have duplicate items) | object { import, dependOn?, filename?, library? } } (should not have fewer than 1 property) | non-empty string | [non-empty string, ...] (should not have fewer than 1 item, should not have duplicate items) -> The entry point(s) of the compilation. Details: * configuration.entry['main'].filename should be one of these: non-empty string | function -> Specifies the name of each output file on disk. You must **not** specify an absolute path here! The `output.path` option determines the location on disk the files are written to, filename is used solely for naming the individual files. Details: * configuration.entry['main'].filename should be a non-empty string. * configuration.entry['main'].filename should be an instance of function. at validate (D:\VS\VueHMR\node_modules\.pnpm\registry.npmjs.org\schema-utils\2.6.4\node_modules\schema-utils\dist\validate.js:85:11) at validateSchema (D:\VS\VueHMR\node_modules\.pnpm\registry.npmjs.org\webpack\5.0.0-beta.14_webpack@5.0.0-beta.14\node_modules\webpack\lib\validateSchema.js:36:2) at webpack (D:\VS\VueHMR\node_modules\.pnpm\registry.npmjs.org\webpack\5.0.0-beta.14_webpack@5.0.0-beta.14\node_modules\webpack\lib\webpack.js:88:2) at Object.<anonymous> (D:\VS\VueHMR\wds-cli.js:48:18) at Module._compile (internal/modules/cjs/loader.js:1158:30) at Object.Module._extensions..js (internal/modules/cjs/loader.js:1178:10) at Module.load (internal/modules/cjs/loader.js:1002:32) at Function.Module._load (internal/modules/cjs/loader.js:901:14) at Function.executeUserEntryPoint [as runMain] (internal/modules/run_main.js:74:12) at internal/main/run_main_module.js:18:47 This is caused by improper configuration by WDS.addDevServerEntrypoints(config, wdsConfig); API:
