koa-underscore-templates v0.2.0

koa-underscore-templates

Render underscore.js templates with Koa.

Works with Koa 2.x or newer.

Getting started

Add this package as a middleware for your application:

const views = require('koa-underscore-templates');

app.use(views(__dirname + '/views', {
  // optional options here...
}));

Then call ctx.render to render the page:

app.use(async (ctx) => {
  await ctx.render('index.html');
});

Middleware

The middleware takes the path of the root directory of the templates as the first parameter. The second parameter is optional, and can contain the following optional options:

• extension (default: .html)
  If non-null, then this will be appended to the file name. For instance, extension: .html would make ctx.render("index.html") render the file index.html.

• settings
  Settings that will be passed directly to _.templates.

• cache (default: true) If true, templates will be cached, so changes to templates may require a restart. If false, templates will be recompiled every time a change occurs.

• globals If given, the properties of this object will be available to all templates.

• ignoreState (default: false) If true, then properties of ctx.state will not be available to templates.

• layout
  Set the layout template. The body variable is available in the layouts.

ctx.render( templateName, [ data, [ options ] ] )

Render a template. Works asynchronously, so you must handle the returned promise.

If ctx.type has not been set, it will be automatically set to html.

Takes the following options:

• layout (optional) If set, overrides the middleware layout option.
