How can I customize the underlying `esbuild` bundling process for a NodejsFunction, such as excluding specific packages or minification options?

You can customize `esbuild` bundling options using the `bundling` prop of `NodejsFunction`. This prop accepts an object with various options that are directly passed to `esbuild`. To exclude specific packages (e.g., not bundling them, assuming they are available in a Lambda Layer or Runtime): use the `externalModules` array. To control minification: ```typescript import { NodejsFunction } from 'aws-cdk-lib/aws-lambda-nodejs'; import { Runtime } from 'aws-cdk-lib/aws-lambda'; new NodejsFunction(this, 'MyFunctionCustomBundling', { entry: 'src/lambda/handler.ts', runtime: Runtime.NODEJS_20_X, bundling: { minify: true, // Enable minification sourcemap: true, // Generate source maps externalModules: ['aws-sdk'], // Exclude AWS SDK if not needed in the bundle nodeModules: ['axios'], // Force bundling specific node_modules even if external define: { 'process.env.MY_VAR': '"myValue"' }, // Define global constants }, }); ```
