Unexpected token <

[wlepinski]

I'm trying to compile a HTML (Handlebars) file to pure HTML and I'm getting this error:

gulp.task('handlebars', function() {
  gulp.src('./src/assets/handlebars/index.html')
    .pipe(hb({
      helpers: './src/assets/handlebars/helpers/**/*.js',
      partials: './src/assets/handlebars/**/*.html',
    }))
    .pipe(gulp.dest('dist/index.html'));
});

[14:36:40] SyntaxError: Unexpected token <

What am I doing wrong here?

I noticed that the plugin is trying to require the .html files using require().

[shannonmoeller]

Yep, that's the issue. Handlebars supports require()ing partials with the extensions .handlebars and .hbs. You'll want to rename your partial files, or add your own extension method.

[wlepinski]

require.extensions['.html'] = function (module, filename) {
  module.exports = fs.readFileSync(filename, 'utf8');
};

Like that, right?

[shannonmoeller]

Close. This should do it:

var fs = require('fs');
var handlebars = require('handlebars');
require.extensions['.html'] = function (module, filename) {
   module.exports = handlebars.compile(fs.readFileSync(filename, 'utf8'));
};

It's not an issue for gulp.src as that reads the file as text.

[wlepinski]

Cool. Closing the issue. Thanks.

I stumbled upon the same issue (want to use partials with .html extension), but I am using the new ES6 module import syntax instead of require:

import hb from 'gulp-hb';

Is there a solution working with this syntax as well?

[shannonmoeller]

@derwaldgeist The module syntax currently de-sugars to a require() call, so the extensions hook still works (as of Node 6).

When native import lands in Node (likely to be v7), I'll make sure this plugin is compatible.

Thanks!
