ejsinbrowser

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
...
require('ejsinbrowser').writeScript({
	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>
<script>
var html = TEMPLATES.mypartial({ name: 'Rob' })
...
</script>

Error Handling

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