Sweet ASCII art. where:

Fen: FEN notation
Key: TODO

Move white king's pawn from e2 to e4:

position startpos moves e2e4

Then display again:

gives:

 | p | p | p | p | p | p | p | p | 7

Key: B46022469E3DD31B

so we see that the pawn moved.

Now let's make Stockfish think for one second what is the next best move for black:

go movetime 1000

gives as the last line:

bestmove c7c5 ponder g1f3

TODO:

what is ponder? Something to do with thinking on the opponent's turn: permanent brain.
understand the previous lines

To make the move it as suggested for black, we have to either repeat the entire sequence of movements:

position startpos moves e2e4 c7c5

d:

Fen: rnbqkbnr/pp1ppppp/8/2p5/4P3/8/PPPP1PPP/RNBQKBNR w KQkq - 0 2
Key: 4CA78BCE9C2980B0

or alternatively we could also use the previous FEN notation as a starting point;

position fen rnbqkbnr/pppppppp/8/8/4P3/8/PPPP1PPP/RNBQKBNR b KQkq - 0 1 moves c7c5

Note how the Universal Chess Interface interface is very simple: we just load a state and then decide what to do next for that one state. The engine holds only one and exactly one state at a time, and you can't even modify it differentially without loading new one from scratch.

Let's move white again with our brain with either:

position startpos moves e2e4 c7c5 d2d3
position fen rnbqkbnr/pp1ppppp/8/2p5/4P3/8/PPPP1PPP/RNBQKBNR w KQkq - 0 2 moves d2d3

Set a specific position from fen:

position fen rnbqkbnr/pppppppp/8/8/4P3/8/PPPP1PPP/RNBQKBNR b KQkq - 0 1

webpack/template contains a reasonable starter template.

This will produce, under dist/ the following minimized files:

dist/index.html: from webpack/template/index.html. You can open it to see:
```
Hello webpack
```
show on the browser. This was added from JavaScript.
dist/index.js: from webpack/template/index.js and anything in its import tree, e.g.:
- webpack/template/main.scss: sass source. It gets embedded the the JavaScript output as a string, and the JavaScript then applies it to the page, making the font blue
- lodash third party library

You can also run this test with the development server on localhost:9000:

npm start

which uses unminimized outptus, and automatically push reloads the page whenever you change any of the input files!

This example shows how to use @cirosantilli/_file/webpack/webpack/sass.

To make things simple, it generates a completely separate dist/index.js and dist/main.css which are manually included from index.html, and does not do any type of injection (neither Js into HTML nor CSS in Js).

This example shows how you could manually include the dist/index.js that is output from webpack into your index.html.

This is generally not what you want to do, because what you actually want to do is to use a Js output name with a hash in it, so that browsers only need to refetch when the name changes.

And to do that, we have to let webpack dynamically inject that unpredictable hash as done in webpack/template with:

new HtmlWebpackPlugin({
  filename: 'index.html',
  // Inject the include to our hashed filename,
  // since it is not deterministic due to the hash.
  inject: true,
  template: path.resolve(__dirname, 'index.html'),
}),
