Usage
Simple:
import HaikuPlayer from "@haiku/player/dom";
const definition = { template: `<div>Hello Haiku!</div>` };
const factory = HaikuPlayer(definition);
const component = factory(document.getElementById("mount"));
Animated:
import HaikuPlayer from "@haiku/player/dom";
const definition = {
timelines: {
Default: {
"#box": {
"style.width": { 0: { value: "100px" }},
"style.height": { 0: { value: "100px" }},
"style.backgroundColor": { 0: { value: "red" }},
"rotation.z": {
0: { value: 0, curve: "linear" },
1000: { value: 3.14159 },
},
},
},
},
template: `
<div id="box">Hello Animation!</div>
`,
};
const factory = HaikuPlayer(definition);
const component = factory(document.getElementById("mount"));
Interactive:
import HaikuPlayer from "@haiku/player/dom";
const definition = {
options: {
autoplay: false,
},
states: {
clicks: {
value: 0,
},
},
eventHandlers: {
"#box": {
"click": {
handler: function () {
this.state.clicks += 1;
this.getTimeline("Default").play();
},
},
},
},
timelines: {
Default: {
"#box": {
"content": { 0: {
value: function (clicks) {
return clicks + "";
},
}},
"style.width": { 0: { value: "100px" }},
"style.height": { 0: { value: "100px" }},
"style.backgroundColor": { 0: { value: "red" }},
"rotation.z": {
0: { value: 0, curve: "linear" },
1000: { value: 3.14159 },
},
},
},
},
template: `
<div id="box"></div>
`,
};
const factory = HaikuPlayer(definition);
const component = factory(document.getElementById("mount"));
Motivation / Goals
With so many great UI libraries out there, why build this engine? Haiku Player is the bedrock of the Haiku app platform, and although we experimented with many existing libraries to meet its needs, in each case we found the architecture or goals mismatched. We opted to build an engine that would serve our plans exactly.
Conceptually, Haiku Player transforms static component definitions (see above) into animated, interactive UIs. It organizes designed elements into a scene graph in which every node can be transformed in 2.5D space. It also serves as a translation layer between the Haiku app platform and rendering APIs (e.g., the browser).
