jsreport toner
node library for dynamic assembling documents and printing them into various formats (written for jsreport)
var toner = ;toner;toner; toner;
Basics
Engines
Documents are assembled using javascript templating engines. The engine needs to be first registered in toner.
toner;
You can write your own engine or use an existing one:
Note that templating engine runs safely in another sand-boxed process. You don't have to be afraid to run user defined templates. See script-manager for details.
You can register and use none
engine to skip its processing:
toner;toner
Recipes
The actual printing of the document into pdf, excel or any other type of the document is done by something we call recipe. The recipe also needs to be registered first.

You can also write your own recipe or use an existing one:
You can use html
recipe to simply produce html:
toner;toner
Render
The complete document generation is invoked using toner.render
function:
toner;
The only parameter is an object representing rendering request. The request has following structure:
//[required] template: //[required] templating engine used to assemble document engine: "jsrender" //[required] recipe used for printing previously assembled document recipe: "wkhtmltopdf" //[required] template for the engine content: "<h1>{{:foo}}</h1>" //javascript helper functions used by templating engines helpers: "function foo() { ...}" + "function foo2() { ... }" //any other settings used by recipes ... //dynamic data inputs used by templating engines data: foo: "hello world" ...
The render callback then contains the response with
//node.js buffer with the document content: ... //stream with the document stream: ... //http response headers with valid content type.. headers: ...
Pipe the document to the http response
var http = ;http;
Hooks
It is expected there will soon popup other packages hooking into the Toner and adding additional functionality. For this case Toner provides several hooks which can be used to extend it.
