Full configuration

samurai.js

import {Samurai} from "samuraijs";

new Samurai({
    paths: {
        source: 'src',
        destination: 'dist',
        assets: ['src/assets'],
        exclude: ['src/templates', 'src/styles', 'src/scripts']
    },
    logLevel: 'debug',
    nunjucks: {
        // https://mozilla.github.io/nunjucks/api.html#configure
        autoescape: true,
        trimBlocks: true,
        noCache: true,
        globals: {
            // https://mozilla.github.io/nunjucks/api.html#addglobal
            hello: (name) => {
                return `Hello, ${name}`
            }
        }
    },
    esbuild: {
        // https://esbuild.github.io/api/#simple-options
        minify: true,
        bundle: true
    },
    sass: {
        // https://sass-lang.com/documentation/js-api#options
        outputStyle: "compressed"
    },
    server: {
        // https://browsersync.io/docs/options
        port: 3000,
        open: false
    },
    fileProcessor: (path) => {
        if (path.lastIndexOf('.jpg') === 0) {
            // Convert a file or do something else ...
            return true;
        }
        return false; // if true, the builder will not touch this file
    }
});

How it works

Source directory tree:

/src/
|  index.njk *
|  index.json
|  index.ts
|  index.scss
|  
|  scripts.ts
|  styles.scss
|  
|  /another-route/
|  |  index.njk *
|  |  index.json
|  |  index.ts
|  |  index.scss
|  |  
|  |  page2.njk
|  |  page2.json
|  |
|  |  _page2-inner-component.njk **
|  |
|  /templates/
|  |  _header.njk **
|  |  _footer.njk **
|  |
|  /scripts/
|  |  module1.ts
|  |  module2.ts
|  |
|  /styles/
|  |  main-styles.scss
|  |  utils.scss
   

* - required file
** - cannot have context *.json file, inner scripts / styles

For each .njk components will be created a .html file that includes a template, script and style:

<style>
    /* Content of *.scss file (compiled) */
</style>
<!-- Content of *.njk file (compiled) -->
<script>
    // Content of *.ts file (compiled)
</script>

Every entry-point can have .json file named like this entry-point. This .json includes context for *.njk file:

/route-one/
|  page.njk
|  page.json

page.njk

<ul>
    {% for item in list %}
    <li>{{ item }}</li>
    {% endfor %}
</ul>

page.json

{
  "list": [
    1,
    2,
    3,
    4,
    5
  ]
}

*.njk files starting with _ will be skipped. Such files will not be considered entry points: _menu.njk.

Every not-entry-point _.njk file should not have context .json file! If this file is exist, it will be ignored.

Another files (like scripts.ts or styles.scss) will be compiled and placed in destination path.

Assets will just be copied to the destination directory.
