Node.js module for rendering beautiful emails with ejs templates and email-friendly inline CSS using juice.
UPDATE: Teelaunch plans to rewrite this module, subscribe to their email newsletter for special updates.
v0.0.7:
- Added support for ejs's
includedirective thanks to @nicjansma
v0.0.6:
- Fixed batch problem (
...has no method slice) thanks to @vekexasia
v0.0.5:
- Added support for an optional zlib compression type (e.g. you can return compressed html/text buffer for db storage)
...
template('newsletter', locals, 'deflateRaw', function(err, html, text) {
// The `html` and `text` are buffers compressed using zlib.deflateRaw
// <http://nodejs.org/docs/latest/api/zlib.html#zlib_zlib_deflateraw_buf_callback>
// **NOTE**: You could also pass 'deflate' or 'gzip' if necessary, and it works with batch rendering as well
})
...v0.0.4 (with bug fix for 0.0.3):
- Removed requirement for
style.cssandtext.ejsfiles with compatibility innodev0.6.x to v0.8.x (utilizespath.existsvs.fs.existsrespectively).

npm install email-templatesnpm install email-templates-windows- Install the module for your respective project
npm install email-templates. - Create a folder called
templatesinside your root directory (or elsewhere). - For each of your templates, respectively name and create a folder inside the
templatesfolder. - Add the following files inside the template's folder:
- You may use the
includedirective from ejs (for example, to include a common header or footer). See the/examplesfolder for details. - Utilize one of the examples below for your respective email module and start sending beautiful emails!
Want to use different opening and closing tags instead of the EJS's default <% and %>?.

emailTemplates(templatesDir, { open: '{{', close: '}}' }, function(err, template) {
...NOTE: You can also pass other options from EJS's documentation.
Render a template for a single email or render multiple (having only loaded the template once).
