BCL builder

The @openeuropa/bcl-builder is a package providing scripts to be executed via
the command line, styles, scripts, copy, rename and sprite.
They can be used respectively to compile SASS files and minify css
files, compile and minify js files, to copy files or rename files and to generate
svg sprites.
It comes with a bin file that is available when the package is installed and
can be run as npm run ecl-builder scriptName.
It supports a configuration file bcl-builder.config.js where each script can
be configured to perform specific operations in the enviroment where they are
used.

The builder uses by default a bcl-builder.config.js in the same folder where the
builder script is executed.
This file will define the different operations you want to perform via the builder.
The config file is basically an export of the configuration for the different
commands which all supports multiple operations as items in an array.

module.exports = { scripts: [{ entry, dest, options } ...], styles: [{ entry, dest, options } ...], rename: [{ entry, dest, options } ...], copy: [{ from, to, options } ...], sprite: [[{ entry, dest, options } ...], };

#### Styles

styles: [ { entry (string), dest (string), options (object) [plugins for postcss] https://github.com/postcss/postcss/blob/main/docs/plugins.md { minify (includes css nano for minification) } }, ],

#### Scripts

scripts: [ { entry (string), dest (string), options: (object) [rollup js configuration https://rollupjs.org/guide/en/#javascript-api] }, }, ],

#### Copy

copy: [ { from: (string), to: (string), options: (object) [copyfiles api conf https://www.npmjs.com/package/copyfiles], }, ],

#### Reaname

rename: [ { from: (string), to: (string), options: (object) { search: (glob), operation: [prefix|suffix|rewrite|extension], }, }, ],

#### Sprite

sprite: [ { entry: (string), dest: (string), options: (object) { file: (string) (defaut: bcl-icons.svg), list: (array of file names) (optional), }, }, ],

#### Color Scheme

``javascript
* Example config object: {
colorScheme: [
{
entry: path.resolve("resources/sass/color-scheme-variables.scss"),
dest: path.resolve(outputFolder, "assets/css/color_scheme.min.css"),
options: {
includePaths,
sourceMap: "file",
},
},
],
`

This following example is the entry of the colorScheme. The scss file should look like this. It also support multiple color schemes.
Example SCSS file of color-scheme.scss:

`scss
$colors-schemes: (
"ocean": (
"primary": #4eac00,
"secondary": #fbff00,
"danger": #ff8800,
"success": #4dff00,
"text": #294d26,
"background": #ffdfb0,
"link": #7b00ff,
),
);
`

The color-scheme enables the possibility to theme the colors used in BCL. It overrides the variables $theme-colors used by Bootstrap (Bootstrap Theme Colors).

We've also added some new variables that overwrite and make use of extra classes:

- .text-color-default: Text color is changed based on the 'text' variable, overriding all text colors inside a component.
- .bg-default: Background color is changed based on the 'background' variable. It adds a background for the component but does not override if it already has a bg class (e.g., bg-primary).

- BCL-Builder version >= 1.2.1
- BCL-Bootstrap version >= 1.2.1
- BCL-Theme-Default >= 1.2.1

Step 1:
Depending on your package manager:

Yarn:

- yarn add @openeuropa/bcl-builder --save
- yarn add @openeuropa/bcl-bootstrap --save
- yarn add @openeuropa/bcl-theme-default --save

NPM:

- npm install @openeuropa/bcl-builder --save
- npm install @openeuropa/bcl-bootstrap --save
- npm install @openeuropa/bcl-theme-default --save

Step 2:
Add the following bcl-builder.config.js file:

`javascript
colorScheme: [
{
entry: path.resolve(outputFolder, "path to the color-scheme scss file"),
dest: path.resolve(outputFolder, "compiled "),
options: {
includePaths,
minify: true,
sourceMap: "file",
},
},
],
`

Step 3:
Add in your package.json the following command:

`javascript
"build:color-scheme": "bcl-builder color-scheme",
`

Note: We are using (npm-run-all package) in BCL in order for all scripts for bcl-builder to be run at once:
Example:

`javascript
"build": "npm-run-all build:*",
"build:styles": "bcl-builder styles",
"build:color-scheme": "bcl-builder color-scheme",
"build:scripts": "bcl-builder scripts",
"build:copy": "bcl-builder copy",
"build:sprite": "bcl-builder sprite",
