How is the sequence of processing and build stages implemented in the project?

In Node.js projects, the sequence of processing and build stages is usually implemented using build tools and task runners such as Webpack, Gulp, or npm scripts. The main stages include:

• Transforming the source code (for example, using Babel to support new JavaScript standards).
• Combining modules into one or more bundles.
• Minifying and optimizing the code to reduce size.
• Copying static resources.
• Running tests and quality checks.

An example of a simple npm script in package.json:

"scripts": {
  "build": "babel src -d dist && webpack --config webpack.config.js"
}

Thus, the stages are arranged in a chain, where the output of one is used as input for the next, ensuring automation and repeatability of the build process.
