Create a tsup.config.ts file in your package root:

Base Library

For standard TypeScript libraries:

import { defineConfig } from 'tsup';
import { preset as basePreset } from '@nesvel/tsup-config';

export default defineConfig(basePreset);

NestJS Library

For NestJS modules and libraries (uses tsc for decorators):

import { defineConfig } from 'tsup';
import { nestLibPreset } from '@nesvel/tsup-config';

export default defineConfig(nestLibPreset);

NestJS Application

For NestJS applications (single-file bundle with shebang):

import { defineConfig } from 'tsup';
import { nestAppPreset } from '@nesvel/tsup-config';

export default defineConfig(nestAppPreset);

CLI Library

For CLI tools and binaries:

import { defineConfig } from 'tsup';
import { cliLibPreset } from '@nesvel/tsup-config';

export default defineConfig(cliLibPreset);

React Library

For React component libraries:

import { defineConfig } from 'tsup';
import { reactLibPreset } from '@nesvel/tsup-config';

export default defineConfig(reactLibPreset);

Custom Configuration

You can override any preset option:

import { defineConfig } from 'tsup';
import { preset as basePreset } from '@nesvel/tsup-config';

export default defineConfig({
  ...basePreset,
  minify: true,
  sourcemap: true,
});

The package also exports utility functions:

import {
  loadPackageJson,
  computeExternals,
  buildBanner,
} from '@nesvel/tsup-config';

const pkg = loadPackageJson();
const externals = computeExternals(pkg);
const banner = buildBanner(pkg);
