For Apply Hot-Reload functionality Follow below points:
Install Required packages by following command.
npm i --save-dev webpack-node-externals start-server-webpack-plugin
Create a new file named with: webpack-hmr.config.js with below code:
const webpack = require('webpack');
const nodeExternals = require('webpack-node-externals');
const StartServerPlugin = require('start-server-webpack-plugin');
module.exports = function(options) {
return {
...options,
entry: ['webpack/hot/poll?100', options.entry],
watch: true,
externals: [
nodeExternals({
allowlist: ['webpack/hot/poll?100'],
}),
],
plugins: [
...options.plugins,
new webpack.HotModuleReplacementPlugin(),
new webpack.WatchIgnorePlugin([/\.js$/, /\.d\.ts$/]),
new StartServerPlugin({ name: options.output.filename }),
],
};
};
Add Code in main.ts file:-
declare const module: any;
async function bootstrap() {
const app = await NestFactory.create(AppModule);
await app.listen(3000);
if (module.hot) {
module.hot.accept();
module.hot.dispose(() => app.close());
}
}
bootstrap();
change in package.json file:-
"start:dev": "nest build --webpack --webpackPath webpack-hmr.config.js"
Use command:
npm run start:dev
