fluid.express.singleTemplateMiddleware

A fluid.express.router component that uses the standard renderer to display the template found at that.options.templateKey.

The handlebars context will be generated from the component itself and the rules found in options.rules.contextToExpose. These are used in the same way as in the dispatcher, i.e. the component's model and the incoming request object are the only things available as a starting point for your rules. By default, the request (path) and query parameters are exposed.

This is particularly relevant when working with initBlock instances, where you might want to incorporate req.params.code or another variable into your model. Assuming you are using the defaults here, any components created using the initBlock helper will have options.req set.

This component will only work if you have set up the fluid.express.hb middleware in your fluid.express instance. If you want to expose request or model variables to handlebars, you will also need to have rules like the following in your fluid.express.hb component's definition:

handlebars: {
 type: "fluid.express.hb",
 options: {
     components: {
         initBlock: {
             options: {
                 contextToOptionsRules: {
                     req: "req"
                 }
             }
         }
     }
 }
},
