gulp-elm


A plugin to compile Elm files with Gulp (or other Vinyl sources).
The latest version (0.8.x) only supports Elm 0.19, use 0.7.x to compile earlier versions of Elm.

Example

``.js
var gulp = require('gulp');
var elm = require('gulp-elm');

gulp.task('elm', function(){
return gulp.src('src/Main.elm')
.pipe(elm({ optimize: true }))
.pipe(gulp.dest('dist/'));
});

gulp.task('elm-bundle', function(){
return gulp.src('src/**/Main.elm')
.pipe(elm.bundle('bundle.js', { optimize: true }))
.pipe(gulp.dest('dist/'));
});
`
