gulp-conkitty

Compile Conkitty Templates

Install

npm install gulp-conkitty --save-dev

Example

var conkitty = require('gulp-conkitty');

gulp.task('conkitty', function() {
    // Compile *.ctpl template files to common.js and tpl.js.
    return gulp.src(['./**/*.ctpl'])
        .pipe(conkitty({common: 'common.js', templates: 'tpl.js'}))
        .pipe(gulp.dest('./build'));
});

Example with dependencies (here is actual example) and source map

var conkitty = require('gulp-conkitty');
var gulpFilter = require('gulp-filter');
var concat = require('gulp-concat');

gulp.task('conkitty', function() {
    var cssFilter = gulpFilter('**/*.css');
    var jsFilter = gulpFilter(['**/*.js', '!tpl.js']); // Everything except tpl.js.

    return gulp.src(['./src/**/*.ctpl'])
        // As the result of Conkitty plugin we get templates commons
        // (in common.js), compiled templates themselves (in tpl.js), and
        // declared in templates dependencies (because deps setting is true).
        .pipe(conkitty({
            common: 'common.js',
            templates: 'tpl.js',
            sourcemap: 'tpl.map',
            deps: true // Append external templates dependencies to the result.
        }))

        // Concat all css files to bundle deps.css.
        .pipe(cssFilter)
        .pipe(concat('deps.css'))
        .pipe(cssFilter.restore())

        // Concat all js files except for tpl.js to bundle deps.js.
        .pipe(jsFilter)
        .pipe(concat('deps.js'))
        .pipe(jsFilter.restore())

        .pipe(gulp.dest('./build')); // Copy deps.css, deps.js, tpl.js and tpl.map to ./build.
});

Life outside current working directory

In order to prevent destructivity, every file created by gulp-conkitty should point somewhere inside current working directory:

    .pipe(conkitty({templates: 'tpl.js'})) // is ok
    // but
    .pipe(conkitty({templates: '../tpl.js'})) // will throw an exception.

It is possible to rebase dependencies from outside your working directory.

Let's say we have project structure like this:

/root
    /lib
        button.css
            .btn {background: red;}                            
        button.ctpl
            button $title
                &"button.css"
                button.btn[type="button"]
                    $title
    /myproj
        page.ctpl
            page
                CALL button "Hello world"
        gulpfile.js
            ...
            gulp.task('conkitty', function() {
                return gulp.src(['./page.ctpl', '../lib/button.ctpl'])
                    .pipe(conkitty({
                        templates: 'tpl.js',
                        deps: true
                    }))
                    .pipe(gulp.dest('./build'));
            });
            ...
        package.json

And we run gulp from /root/myproj directory:

[gulp] Error in plugin 'gulp-conkitty': File `../lib/button.css` is outside current working directory

To fix that, we need to rebase outside dependencies and instead of deps: true in gulpfile.js add rebase map:

    .pipe(conkitty({
        templates: 'tpl.js',
        deps: {'../lib': './outerlib/'}
    }))

After that, gulp will run conkitty task fine and /root/myproj/build directory will look like:

/build
    /outerlib
        button.css
    tpl.js

You can rebase multiple directories from outside your working directory and use relative and absolute paths.

External libraries of templates

There is a bit of syntax sugar to add external libraries of templates.

.pipe(conkitty({
    templates: 'tpl.js',
    deps: true, // sould be enabled.
    libs: {
        // We could have npm package with library of templates.
        superlib: require('mysuperlib')
    }
}))

In this example require('mysuperlib') should return an object with two properties:

• require('mysuperlib').BASE should be an absolute path to library's base directory
• require('mysuperlib').FILES should be an array of paths to template files.

mysuperlib file structure could look like:

/mysuperlib
    package.json
    mysuperlib1.ctpl
    mysuperlib2.ctpl
    index.js
        module.exports = {
            BASE: __dirname, // Actual path to index.js.
            FILES: ['mysuperlib1.ctpl', 'mysuperlib2.ctpl']
        };

Dependencies of external library (if any) will be rebased using libs object key:

.pipe(conkitty({
    templates: 'tpl.js',
    deps: true,
    libs: {
        superlib: require('mysuperlib'), // Dependencies will go to `superlib/*`
        'complex/path/lib': require('mysuperlib2') // Dependencies will go to `complex/path/lib/*`
    }
}))

Exclude concat.js from common file

By default concat.js is built in common file. You can exclude concat.js from common file:

gulp.task('conkitty', function() {
    // Compile *.ctpl template files to common.js and tpl.js.
    return gulp.src(['./**/*.ctpl'])
        .pipe(conkitty({
            common: {file: 'common.js', 'concat.js': false},
            templates: 'tpl.js'
        }))
        .pipe(gulp.dest('./build'));
});

Passing environment object for precompile expressions

You can pass environment object for precompile expressions:

gulp.task('conkitty', function() {
    // Compile *.ctpl template files to common.js and tpl.js, pass environment
    // object for precompile expressions.
    return gulp.src(['./**/*.ctpl'])
        .pipe(conkitty({
            env: {prop1: 111, prop2: 'dark', prop3: true},
            common: 'common.js',
            templates: 'tpl.js',
        }))
        .pipe(gulp.dest('./build'));
});
