I'm stucked with the problem of watching my Swig.js html templates and piling them on every change, I use Gulp.js task runner for that purpose. Here is my gulpfile.js:

var gulp = require('gulp');
var myth = require('gulp-myth');
var swig = require('gulp-swig');
var nodemon = require('gulp-nodemon');

gulp.task('styles', function () {
  gulp.src('./myth/*.css')
    .pipe(myth())
    .pipe(gulp.dest('./client/css'));
});

gulp.task('templates', function () {
  gulp.src('./views/*.html')
    .pipe(swig({ load_json: true }))
    .pipe(gulp.dest('./client'));
});

gulp.task('server', function () {
  gulp.run('styles');
  gulp.run('templates');

  gulp.src('./server.js').pipe(nodemon());

  gulp.watch('./myth/*.css', function () {
     gulp.run('styles');
  });

  gulp.watch('./views/*.html', function () {
     gulp.run('templates');
  }); 
});

Myth task styles runs fine - on every change of myth/*.css I got updated file in client/css/..

But task called templates gives result only once.. When I change views/index.html file in client/index.html stays the same. In my console I see that templates task was ran but results still the same..

Maybe I'm missing some cache options or similar?!

• 1 See this issue. Swig caches templates by default and as of yet, there isn't a way to turn off caching with gulp-swig. – robertklep Commented Jan 11, 2014 at 15:26
• @robertklep thanks! hope this guys will merge soon! – Kosmetika Commented Jan 12, 2014 at 15:38

Gulp-Swig has been updated to allow disabling of the cache option - as well as setting other swig defaults, as shown below.

gulp.task('templates', function() {
  gulp.src('./views/*.html')
    .pipe(swig({
      load_json: true,
      defaults: {
        cache: false,
        locals: {
          site_name: "My Blog"
        }
      }
    }))
    .pipe(gulp.dest('./client'));
});

Edit: Configuration may no longer work as per Mike Aski's ment

I had a similar issue where gulp-livereload and tiny-lr was refreshing the page but not showing an updated template. I'm not using gulp-swig (although that looks like a good solution), so I just changed app.js:

swig = require("swig");

swig.setDefaults({
  cache: false
});

app = express();

app.set('view cache', false);
