OrangutanJS - oView

Interface-like class with a lot of implemented ready methods from which we can inherit

Quick start

npm i ojs-view

Package on npm

This package works closely together with ojs-core and ojs-store. So we recommend using it together.

oView implements few methods:

• components

blank method that is called in init and render. In this method, we should declare the components to be rendered again when the state changes

• build

this is the main method in which we declare the body of our class. Example use:

build() {
    return o('div').class('container').add([
        o('p').text('Hello World!').init(),
    ]).init()
}

• fetchData

simple method to fetch data. There are three arguments: url, method and responseType. Method and responseType has default values: GET and json. Example use:

fetchData('https://randomuser.me/api/?results=5')
.then(resp => console.log(resp))

//same as
fetchData('https://randomuser.me/api/?results=5', 'GET', 'json')
.then(resp => console.log(resp))

• rerender

This method we can call to render again whole class. We can call it whenever we want. For example:

exampleInput.addEventListener('change',(e) => {
    this.store.exampleValue = e.target.value;
    this.rerender()
})

This method works perfectly with ojs-store. Will be called every time when observable fields in oStore changes. Example:

this.store = oStore({
    exampleValue: 0
}, this.rerender)

but in this case we can pass only this to oStore function. You can read more about it here

• init

this method just return the HTMLElement. All you have to do is appendChild to the desired location.

Example use:

class without oView:

class Counter {
  constructor(startValue) {
    this.store = oStore({
        counter: startValue
      },
      this);

    this.html = o('div')
      .id('counter')
      .add([this.build()])
      .init();
  }

  rerender() {
    const container = document.getElementById('counter');
    if (counter) {
      container.innerHTML = '';
      container.appendChild(this.build());
    }
  }

  build() {
    return o('button')
      .text(`+${this.store.counter}`)
      .click(() => {
        this.store.counter++;
      })
      .init();
  }
  init() {
    return this.html;
  }
}

const counter = new Counter(0);
document.body.appendChild(counter.init());

and same class with oView:

class Counter extends oView {
  constructor(startValue) {
    this.store = oStore({
        counter: startValue
      }, this);
  }
  
  build() {
    return o('button')
      .text(`+${this.store.counter}`)
      .click(() => {
        this.store.counter++;
      })
      .init();
  }
}

const counter = new Counter(0);
document.body.appendChild(counter.init());
