A Julia wrapper for Vue.js. It uses WebIO to load JavaScript and to do Julia to JS communication. Go here to get started with WebIO.
The package exports a single vue function which mirrors the Vue instance constructor:
vue(template, data; options...)template acts as the template for the vue instance. See Vue's HTML-based syntax. You can compose the template (like any HTML) using WebIO.data is an iterable of propertyName => value pairs (e.g. a Dict) which populates the template.using Vue
template = dom"p[v-if=visible]"("{{message}}")
vue(template, [:message=>"hello", :visible=>true])If a property's value is an observable, this function syncs the property and the observable. Here's how you can update the properties bound to the template from Julia.
ob = Observable("hello")
vue(template, [:message=>ob, :visible=>true])Now if at any time you run ob[] = "hey there!" on Julia, you should see the contents of the message update in the UI. Try making an observable for :visible property and set it to true or false, you should see the message toggle in and out of view!
To initiate JS to Julia communication you must set an event handler on scope[propertyName] (by calling on(f, scope[propertyName])) before rendering the scope.
Here's an example of JS to Julia communication:
incoming = Observable("")
on(println, incoming) # print to console on every update
template = dom"input[type=text,v-model=message]"()
vue(template, [:message=>incoming])This will cause the value of the textbox to flow back to Julia, and should get printed to STDOUT since we have a listener to print it.
You can pass any other options for the Vue constructor as keyword arguments to
vue E.g. vue(...; methods=Dict(:sayhello=>@js function(){ alert("hello!") })) (Tip: use JSExpr.jl for the @js macro)
That's it! :-)
