blorp: Small and mighty React-like that goes "blorp"
blorp aims to make it easy to build dynamic UIs without the need for fancy compilation.
Think of it as a reduction of the best parts of React, without any magic!
installation via npm install --save blorp.
Overview / Examples
Basic rendering can be done as follows:
// with html:
// <body><div id="root"></div></body>
import {div, p, h1, render} from 'blorp';
const component = div([
h1("Hello, world!"),
p("I'm blorp!")
]);
render(component, document.getElementById('root'));Hooks
Blorp has 3 hooks: useState, useEffect, and useContext;
Hooks in blorp are similar to their React counterparts, but are provided slightly differently:
import {div, button, render} from 'blorp';
const component = ({ useState }) => {
const [isClicked, setIsClicked] = useState(false);
return div([
div(isClicked ? "clicked" : "unclicked!"),
button({onclick: () => setIsClicked(true)}, "click me!!"),
]);
};
render(component, document.getElementById('root'));Blorp's hook model allows for true referential transparency in functions, allowing for nested hook usage, even with conditionals!
import {div, render} from 'blorp';
const component = div([
h1("Click below I guess!"),
({useState}) => {
const [outerState, setOuterState] = useState(true);
if (!outerState) {
return null;
}
return div(({ useState }) => {
const [innerState, setInnerState] = useState("todo text");
return `inner state: ${innerState}`;
});
}
]);
render(component, document.getElementById('root'));Some More Details for all Who Want Them
If you're here, you clearly want to know more.
Blorp's node and component model.
BlorpNodes are anything that Blorp can render. The output of div(), span(), frag(), or any other element is a BlorpNode. A Component in blorp is simply a function from Hooks to an optional BlorpNode
In most cases where you pass in a Component, you can just directly pass in a Blorp Node instead.
Dom Diffing
Blorp uses incremental dom, rather than creating a virtual dom.
Keys
When determining which state lines up to which element in a constantly-changing web app, Blorp (like React), uses keys. While keys in React are represented as props, keys in blorp are more separated. Keys can be set via the key() function.
When rendering a series of child nodes, Blorp uses a "first come, first serve" model for lining up internal states to branches in the tree, taking keys into account.
