Karax provides +a tiny build tool called ``karun`` that generates the HTML boilerplate code that +embeds and invokes the generated JavaScript code:: + + nim c karax/tools/karun + karax/tools/karun -r helloworld.nim + +Via ``-d:debugKaraxDsl`` we can have a look at the produced Nim code by +``buildHtml``: + +.. code-block:: nim + + let tmp1 = tree(VNodeKind.tdiv) + add(tmp1, text "Hello World!") + tmp1 + +(I shortened the IDs for better readability.) + +Ok, so ``buildHtml`` introduces temporaries and calls ``add`` for the tree +construction so that it composes with all of Nim's control flow constructs: + + +.. code-block:: nim + + include karax / prelude + import random + + proc createDom(): VNode = + result = buildHtml(tdiv): + if random(100) <= 50: + text "Hello World!" + else: + text "Hello Universe" + + randomize() + setRenderer createDom + + +Produces: + +.. code-block:: nim + + let tmp1 = tree(VNodeKind.tdiv) + if random(100) <= 50: + add(tmp1, text "Hello World!") + else: + add(tmp1, text "Hello Universe") + tmp1 + + +Event model +=========== + +Karax does not change the DOM's event model much, here is a program +that writes "Hello simulated universe" on a button click: + +.. code-block:: nim + + include karax / prelude + + var lines: seq[kstring] = @[] + + proc createDom(): VNode = + result = buildHtml(tdiv): + button: + text "Say hello!" + proc onclick(ev: Event; n: VNode) = + lines.add "Hello simulated universe" + for x in lines: + tdiv: + text x + + setRenderer createDom + + +``kstring`` is Karax's alias for ``cstring`` (which stands for "compatible +string"; for the JS target that is an immutable JavaScript string) which +is preferred for efficiency on the JS target. However, on the native targets +``kstring`` is mapped to ``string`` for efficiency. The DSL for HTML +construction is also avaible for the native targets (!) and the ``kstring`` +abstraction helps to deal with these conflicting requirements. + +Karax's DSL is quite flexible when it comes to event handlers, so the +following syntax is also supported: + +.. code-block:: nim + + include karax / prelude + from future import `=>` + + var lines: seq[kstring] = @[] + + proc createDom(): VNode = + result = buildHtml(tdiv): + button(onclick = () => lines.add "Hello simulated universe"): + text "Say hello!" + for x in lines: + tdiv: + text x + + setRenderer createDom + + +The ``buildHtml`` macro produces this code for us: + +.. code-block:: nim + + let tmp2 = tree(VNodeKind.tdiv) + let tmp3 = tree(VNodeKind.button) + addEventHandler(tmp3, EventKind.onclick, + () => lines.add "Hello simulated universe", kxi) + add(tmp3, text "Say hello!") + add(tmp2, tmp3) + for x in lines: + let tmp4 = tree(VNodeKind.tdiv) + add(tmp4, text x) + add(tmp2, tmp4) + tmp2 + +As the examples grow larger it becomes more and more visible of what +a DSL that composes with the builtin Nim control flow constructs buys us. +Once you have tasted this power there is no going back and languages +without AST based macro system simply don't cut it anymore. + + +DOM diffing +=========== + +Ok, so now we have seen DOM creation and event handlers. But how does +Karax actually keep the DOM up to date? The trick is that every event +handler is wrapped in a helper proc that triggers a *redraw* operation +that calls the *renderer* that you initially passed to ``setRenderer``. +So a new virtual DOM is created and compared against the previous +virtual DOM. This comparison produces a patch set that is then applied +to the real DOM the browser uses internally. This process is called +"virtual DOM diffing" and other frameworks, most notably Facebook's +*React*, do quite similar things. The virtual DOM is faster to create +and manipulate than the real DOM so this approach is quite efficient. + + +Form validation +=============== + +Most applications these days have some "login" +mechanism consisting of ``username`` and ``password`` and +a ``login`` button. The login button should only be clickable +if ``username`` and ``password`` are not empty. An error +message should be shown as long as one input field is empty. + +To create new UI elements we write a ``loginField`` proc that +returns a ``VNode``: + +.. code-block:: nim + + proc loginField(desc, field, class: kstring; + validator: proc (field: kstring): proc ()): VNode = + result = buildHtml(tdiv): + label(`for` = field): + text desc + input(class = class, id = field, onchange = validator(field)) + +We use the ``karax / errors`` module to help with this error +logic. The ``errors`` module is mostly a mapping from strings to +strings but it turned out that the logic is tricky enough to warrant +a library solution. ``validateNotEmpty`` returns a closure that +captures the ``field`` parameter: + +.. code-block:: nim + + proc validateNotEmpty(field: kstring): proc () = + result = proc () = + let x = getVNodeById(field) + if x.text.isNil or x.text == "": + errors.setError(field, field & " must not be empty") + else: + errors.setError(field, "") + +This indirection is required because +event handlers in Karax need to have the type ``proc ()`` +or ``proc (ev: Event; n: VNode)``. The errors module also +gives us a handy ``disableOnError`` helper. It returns +``"disabled"`` if there are errors. Now we have all the +pieces together to write our login dialog: + + +.. code-block:: nim + + # some consts in order to prevent typos: + const + username = kstring"username" + password = kstring"password" + + var loggedIn: bool + + proc loginDialog(): VNode = + result = buildHtml(tdiv): + if not loggedIn: + loginField("Name :", username, "input", validateNotEmpty) + loginField("Password: ", password, "password", validateNotEmpty) + button(onclick = () => (loggedIn = true), disabled = errors.disableOnError()): + text "Login" + p: + text errors.getError(username) + p: + text errors.getError(password) + else: + p: + text "You are now logged in." + + setRenderer loginDialog + +(Full example `here `_.) + +This code still has a bug though, when you run it, the ``login`` button is not +disabled until some input fields are validated! This is easily fixed, +at initialization we have to do: + +.. code-block:: nim + setError username, username & " must not be empty" + setError password, password & " must not be empty" + +There are likely more elegant solutions to this problem. + + +Routing +======= + +For routing ``setRenderer`` can be called with a callback that takes a parameter of +type ``RouterData``. Here is the relevant excerpt from the famous "Todo App" example: + +.. code-block:: nim + + proc createDom(data: RouterData): VNode = + if data.hashPart == "#/": filter = all + elif data.hashPart == "#/completed": filter = completed + elif data.hashPart == "#/active": filter = active + result = buildHtml(tdiv(class="todomvc-wrapper")): + section(class = "todoapp"): + ... + + setRenderer createDom + +(Full example `here `_.)
