dom-crud

Make dom manipulation funny while create, read, update, delete

👉 Install

• If use with script tag, you need to invoke apis using crud. prefix :

<script src="https://unpkg.com/dom-crud@latest/build/index.umd.min.js"></script>
<script>
    // using crud as a namespace to invoke methods
    crud.methodName(...)
</script>

• If use as es module: npm i dom-crud or yarn add dom-crud :

import { methodName } from "dom-crud"
// detail usage are below

👉 Basic Knowledge

Before going on, there are some terms you should know ：

• Sign represents a string contains two character, there are three signs ：

  • == mean overwrite/replace
  • -= mean delete
  • += mean append

• KVS string (short for "Key Value Sign") is a function parameter format in string style what will be used often：there are some [Builtin Keys](#Builtin Keys) for use, every other keys will be used with setAttribute method. Examples :

  • class-=a b c
  • style==color:red;font-size:2rem
  • html+=<span>hi</span>
  • id==a

• KVSC string ("C" is short for "Config"), because some keys can have additional configs, details will discuss later. Examples :

  • id==a?configA=xx&configB=yy

• KVS object is a function parameter format in object style what will be used often. Examples :

  • { 'id==': {value:'a'}}
  • you can also specify value directly: { 'id==':'a'} is equal to above
  • { 'class-=': {value: 'a b c'}} or { 'class-=': 'a b c'}
  • { 'style==': 'color:red;font-size:2rem'}
  • { 'html+=': '<span>hi</span>'}

• KVSC object , Example :

  • use config key and value key at the same time if you need to pass configs: { 'text==': { value:"new text", config: {purText: true} }}

👉 API

cdom(htmlTagName, strOrObj1, strOrObj2, strOrObj3, strOrObj4, ...)

• htmlTagName : string
• strOrObj : KVS(C) string or KVS(C) object)
• **return ** : HtmlElement

import {cdom} from 'dom-crud'

// below will create a dom like this:
// <input type='text' class='center big red' style='font-size:3rem;font-weight:bold'/>

// you can pass only KVS strings
const $input = cdom('input', 
'class==center big red', 
'style==font-size:3rem;font-weight:bold', 
'type==text'
);

// or pass only KVS objects
const $input2 = cdom('input', 
{
  'class==': 'center big red',
  'style==': "font-size:3rem;font-weight:bold",
}, 
{
  'type': 'text'
});

// or mixed
const $input3 = cdom('input', 
'class==center big red',
{
  'style==': "font-size:3rem;font-weight:bold",
  'type==': 'text'
});

rdom(selector)

• selector : string same as querySelector
• return : HtmlElement

import {rdom} from 'dom-crud'

// when reading single dom, you can chain it
const $input = rdom('.center').rdom('.word').rdom('.c'); 

rdoms(selector)

• selector : string same as `querySelectorAll
• **return **: NodeList

import {rdoms} from 'dom-crud'

// multi doms cannot chain
const $inputs = rdoms('input'); 

udom(dom, strOrObj1, strOrObj2, strOrObj3, strOrObj4, ...);

• dom : Element
• strOrObj : KVS(C) string or KVS(C) object
• return : void

import {udom, rdom} from 'dom-crud'

// below will remove all inline styles and then add blue color
udom(rdom('input'), 'style==color:blue;');
// object style
udom(rdom('input'), {
    'style==':'color:blue'
});


// below will only remove color and font-size from inline styles if exists
udom(rdom('input'), 'style-=color;font-size')
// object style
udom(rdom('input'), {
    'style-=':'color;font-size'
})

// below will append color to inline styles
udom(rdom('input'), 'style+=color:blue;')
// object style
udom(rdom('input'), {
    'style+=':'color:blue'
})

ddom(dom)

• dom : Element
• return : boolean whether or not removed dom

import {ddom, rdom} from 'dom-crud'

ddom(rdom('input')); 

getCrudConfig()

• return : global config object

  currently, the default global config is very simple as below:

import { getCrudConfig } from 'dom-crud'
const config = getCrudConfig();
console.log(config);
/*
{
  text: {
    // detailed below
    pureText: false
  },
  // whether log debug info(currently, nothing cumbersome logged)
  debug: false
} 
*/

updateCrudConfig(config)

• config : it should be a subset of global config object, anything else will be ignored
• return : void

import { getCrudConfig, updateCrudConfig } from 'dom-crud'
const config = getCrudConfig();
updateCrudConfig({
    text: {
        pureText: true,
        elseConfig: 'yes' // ignored because global config not contains this
    },
})

👉 Builtin Keys

Below list all builtin keys which made dom-crud funny. Remind: any other keys will be used in setAttribute(key, value) ：

text

This key modifies text conent in target dom, V(value) should be string. This key's configs as below:

name	type	description
pureText	boolean	If your dom content is 100% plain text, set it to true to make performance boost. This config can be changed by global config.

html

This key modifies html content in target dom, V(value) should be string.

doms

This key modifies doms in target dom，V(value) should be one of below :

• array contains Emelent
• NodeList
• ``HTMLCollection`

This key's configs as below:

name	type	description
before	Element	Remind: Element should child of parent element

style

This key modifies dom inline styles.

class

This key modifies dom classes.

For more keys? Please give me advice🤣
