Creating a hosting context

F#

Creating a hosting context for IronJS is very simple, first you open the namespaces and modules you'll need:

open IronJS
module IronJS = IronJS.Hosting.FSharp

Then call createContext on the IronJS.Hosting.FSharp (aliased as IronJS):

let ctx = IronJS.createContext()

To execute JavaScript source code you have access to the following methods on the Hosting.FSharp module

• execute : string -> IronJS.Hosting.FSharp.T -> obj
• executeAs<'a> : string -> IronJS.Hosting.FSharp.T -> 'a
• executeFile : string -> IronJS.Hosting.FSharp.T -> obj
• executeFileAs<'a> : string -> IronJS.Hosting.FSharp.T -> 'a

For working with global values you have access to the following fucntions:

• setGlobal: string -> obj -> IronJS.Hosting.FSharp.T -> unit
• getGlobal: string -> IronJS.Hosting.FSharp.T -> IronJS.BoxedValue
• getGlobalAs<'a>: string -> IronJS.Hosting.FSharp.T -> 'a

You can also access the IronJS environment object and the globals object with the following functions

• env: -> IronJS.Hosting.FSharp.T -> IronJS.Environment
• globals: -> IronJS.Hosting.FSharp.T -> IronJS.CommonObject
