Do I really need Rollup and esbuild?

[guest271314]

I'm using esbuild to bundle a TypeScript file to JavaScript. I am using Rollup to generate a file. Can one or the other be used for both actions?

await esbuild.build({
  entryPoints: ["src/index.ts"],
  platform: "node",
  outfile: dynamicImport,
  format: "esm",
  packages: "external",
  legalComments: "inline",
  sourcemap: true,
  bundle: true,
  keepNames: true,
  allowOverwrite: true
});

const bundle = await rollup.rollup({
  input: "./src/script.js",
  plugins: [
    // ...
  ],
});
