Packages ejs templates as external javascript so they can be rendered in the browser without runtime. By Harald Rudell.


Packages ejs templates in an external javascript file so they can be rendered in the browser with no runtime overhead. # Usage in your express app.js:

app = createServer
    folder: app.settings.views,
    ext: app.settings['view engine'],
    jsGlobalVariable: 'TEMPLATES',
    templates: 'partials',
    filename: __dirname + '/public/javascripts/templates.js'

This creates templates.js on server launch, and you can then in the browser page render the server's file views/partials/mypartial.ejs likeso:

<script src=/javascripts/templates.js></script>
var html = TEMPLATES.mypartial({ name: 'Rob' })

Error Handling

Rendering exceptions are caught and displayed using alert: "ReferenceError: gghhjj is not defined template:badtemplate line:2"



  • opt.folder: (optional) base folder for express templates, eg '/home/user/views'
  • opt.ext: (optional) extension for express templates, eg. 'ejs'
  • opt.jsGlobalVariable: global variable identifier used to accesss templates in browse, eg. 'TEMPLATES'
  • opt.filename: the output filename eg. '/home/user/public/javascripts/templates.js'
  • opt.templates: template filenames and folder names, single string or array
  • opt.minify: minify the result


  • Templates are compiled server side on startup
  • No JavaScript runtime is required in the browser
  • Executable JavaScript functions are provided in the browser
  • An alternative is to use underscore templates in express, see the module uinexpress
