Motivation

Quicker development iterations than with tsc

You can use this section in the docs to setup SWC. Unfortunately, you have to do it in every NestJS application.

Basically, you just have to paste this code in your webpack.config.js in every app.

const { composePlugins, withNx } = require('@nx/webpack');

const swcDefaultConfig =
  require('@nestjs/cli/lib/compiler/defaults/swc-defaults').swcDefaultsFactory()
    .swcOptions;

module.exports = composePlugins(withNx(), (config) => {
  config.module.rules.push({
    test: /\.ts$/,
    exclude: /node_modules/,
    use: {
      loader: 'swc-loader',
      options: swcDefaultConfig,
    },
  });
  return config;
});

Of course, make sure that you have the nestjs/cli installed locally in the project.

EDIT: With further inspection, I'm actually not seeing any speed improvements with this fix.

I think this does the trick:

const { composePlugins, withNx } = require('@nx/webpack');

// Nx plugins for webpack.
module.exports = composePlugins(
  withNx({
    target: 'node',
    compiler: 'swc',
  }),
  (config) => {
    // Update the webpack config as needed here.
    // e.g. `config.plugins.push(new MyPlugin())`
    return config;
  }
);

I think this does the trick:

const { composePlugins, withNx } = require('@nx/webpack');

// Nx plugins for webpack.
module.exports = composePlugins(
  withNx({
    target: 'node',
    compiler: 'swc',
  }),
  (config) => {
    // Update the webpack config as needed here.
    // e.g. `config.plugins.push(new MyPlugin())`
    return config;
  }
);

For me, it is the same as the solution above, no speed improvement.

Any updates?.. In my case I've tried few different ways yet still can't run nest with swc under nx.

[gperdomor]

I would like to having this too 🙏🏻

Sorry for the late response.

This should already be supported. Enabling it should be to change the compiler options the webpack config via withNx({ compiler: 'swc' }) this should add the appropriate loader.
