gulp-elm-css v0.1.0

gulp-elm-css

Given an *.elm file, it will use elm-css to generate *.css files. A vinyl object will be emitted for each *.css file that is generated.

Example

on the elm side

-- HomeCss.elm

module HomeCss exposing (..)

import Css exposing (..)
import Css.Namespace exposing (namespace)


type CssIds
    = Home


css =
    (stylesheet << namespace "home")
        [ id Home
            [ backgroundColor (hex "000000")
            , color (hex "FFFFFF")
            ]
        ]

-- MyStyles.elm

port module MyStyles exposing (..)

import Css.File exposing (CssFileStructure, CssCompilerProgram)
import AboutCss
import HomeCss
import SharedCss


port files : CssFileStructure -> Cmd msg


fileStructure : CssFileStructure
fileStructure =
    Css.File.toFileStructure
        [ ( "shared.css", Css.File.compile [ SharedCss.css ] )
        , ( "home.css", Css.File.compile [ HomeCss.css ] )
        , ( "about.css", Css.File.compile [ AboutCss.css ] )
        ]


main : CssCompilerProgram
main =
    Css.File.compiler files fileStructure

on the gulp side

const elmCss = require('gulp-elm-css')

gulp.task('compile-css', () => {
  return gulp.src('MyStyles.elm')
    .pipe(elmCss({ module: 'MyStyles '}))
    .pipe(cssnano())
    .pipe(gulp.dest('build'))
})
