With ESBuild, add this block when calling esbuild.build():

`ts
import * as esbuild from 'esbuild';
import dtsBundleGenerator from 'unplugin-dts-bundle-generator/rollup';

await esbuild.build({
plugins: [
dtsBundleGenerator({
outfile: 'my-lib.d.ts',
output: {
// output config
},
libraries: {
// libraries config
},
compilation: {
// compilation options
}
}),
],
entryPoints: 'src/index.ts',
outfile: 'my-lib.js',
format: 'esm',
bundle: true,
});
`



With Rolldown, add this block to your rolldown.config.ts:

`ts
import dtsBundleGenerator from 'unplugin-dts-bundle-generator/rolldown';

export default {
plugins: [
dtsBundleGenerator({
file: 'my-lib.d.ts',
output: {
// output config
},
libraries: {
// libraries config
},
compilation: {
// compilation options
}
}),
],
input: 'src/index.ts',
output: {

};
`



With Rollup, add this block to your rollup.config.ts:

`ts

With Vite, add this block to your vite.config.ts:

`ts
import path from 'node:path';

export default defineConfig({
plugins: [
dtsBundleGenerator({
fileName: 'my-lib.d.ts',
output: {
