The Glimmer Pipeline 1. Pre-Compilation 2. Initial render 3. Re-render
Pre-Compilation Templates are pre-compiled (at build time) into opcodes that
the Glimmer VM executes during initial render
<ul class="nav nav-tabs"> <li class="active"> <a href="/home">{{home}}</a> </li> <li> <a
href="/profile">{{profile}}</a> </li> <li> <a href="/messages">{{messages}}</a> </li> </ul>
[ [6,"ul"], [9,"class","nav nav-tabs"], [7] [0," \n "], [6,"li"], [9,"class","active"],
[7], [0,"\n "], [6,"a"], [9,"href","/home"], [7], [1, [18,"home"], false ], [8], [0,"\n "], [8], … [0,"\n"], [8] ]

Initial render DOM elements are created and opcodes for re-renders
are generated
[ [6,"ul"], [9,"class","nav nav-tabs"], [7] [0," \n "], [6,"li"], [9,"class","active"],
[7], [0,"\n "], [6,"a"], [9,"href","/home"], [7], [1, [18,"home"], false ], [8], [0,"\n "], [8], … [0,"\n"], [8] ]
<ul class="nav nav-tabs"> <li class="active"> <a href="/home">Start</a> </li> <li> <a
href="/profile">Profil</a> </li> <li> <a href="/messages">Nachrichten</a> </li> </ul>
<ul class="nav nav-tabs"> <li class="active"> <a href="/home">{{home}}</a> </li> <li> <a
href="/profile">{{profile}}</a> </li> <li> <a href="/messages">{{messages}}</a> </li> </ul> only these can change at all
[ ["OPTIMIZED-CAUTIOUS-UPDATE", "home"], ["OPTIMIZED-CAUTIOUS-UPDATE", "profile"], ["OPTIMIZED-CAUTIOUS-UPDATE", "messages"] ]
Update Renders Update opcodes are executed
let foo = 1; let fooReference: Reference<number> = { value()
{ return foo; } }; fooReference.value(); // => 1 foo++; fooReference.value(); // => 2
let foo = 1; let bar = 2; let fooReference:
Reference<number> = { value() { return foo; } }; let barReference: Reference<number> = { value() { return bar; } }; let fooPlusBarReference: Reference<number> = { value() { return fooReference.value() + barReference.value(); } }; fooPlusBarReference.value(); // => 3 foo = 2; fooPlusBarReference.value(); // => 4
interface EntityTag<T> { value(): T; validate(ticket: T): boolean; } interface
Tagged { tag: EntityTag<any>; } interface TaggedReference<T> extends Reference<T>, Tagged { }
const person: TrackedObject = { tag: new DirtyableTag(), name: 'Godfrey
Chan' }; let nameReference: VersionedReference<string> { tag: person.tag, value() { return person.name; } }; nameReference.value(); // => 'Godfrey Chan' nameReference.tag.value(); // => 1 person.name = 'Yehuda Katz'; nameReference.tag.validate(1); // => false nameReference.value(); // => 'Yehuda Katz' nameReference.tag.value(); // => 2
class UpdateOpcode { execute() { if (!this.reference.tag.validate(this._lastTag)) { this._lastTag =
this.reference.tag.value(); let newValue = this.reference.value(); this.domNode.textContent = newValue; // update DOM } } }

Like React, Glimmer.js is only the "V" and some of
the "C" in "MVC" (aka components)
