Display comments on the basis of user authentication

If the prop currentUser is undefined, the comment section refers to the signinUrl or signupUrl props to redirect the user to the given URLs

Component API

All the props that you will require for using this library

currentUser

This prop is required to give currently logged in user's details.

object | require

currentUser={{ userId: userId, avatarUrl: avatarUrl, name:name}}

commentsArray

This prop is required to give an array of comments in this format strictly.

JSON Array | require

[
  {
    "userId": "01a",
    "comId": "012",
    "fullName": "Riya Negi",
    "avatarUrl": "https://ui-avatars.com/api/name=Riya&background=random" ,
    "text": "Hey, Loved your blog! ",
    "replies": [
      {
        "userId": "02a",
        "comId": "013",
  
        "fullName": "Adam Scott",
        "avatarUrl": "https://ui-avatars.com/api/name=Adam&background=random" ,
        "text": "Thanks! It took me 1 month to finish this project but I am glad it helped out someone!🥰"
      },
      {
        "userId": "01a",
        "comId": "014",
  
        "fullName": "Riya Negi",
        "avatarUrl": "https://ui-avatars.com/api/name=Riya&background=random",
        "text": "thanks!😊"
      }
    ]
  },
  {
    "userId": "02b",
    "comId": "017",
    "fullName": "Lily",
    "text": "I have a doubt about the 4th point🤔",
    "avatarUrl": "https://ui-avatars.com/api/name=Lily&background=random"
  },
  {
    "userId": "01c",
    "comId": "018",
    "fullName": "Derek",
    "text": "Great explanation!!!",
    "avatarUrl": "https://ui-avatars.com/api/name=Derek&background=random"
  }
]

setComment

This prop is required to give a set-state function to keep the parent component's state updated.

func | require

setComment={this.handleState}

signinUrl

This prop is given in addition to the currentUser prop, so that if no user is logged in, It can redirect it to the login link.

string | optional

signinUrl="/signin"

signupUrl

This prop is given in addition to the currentUser prop, so that if no user is logged in, It can redirect it to the signup/registeration link.

string | optional

signupUrl="/signup"

customInput

This is an optional prop to give users the flexibility of adding their own custom input field.

func | optional

const customInputFunc = (props) => {
    return <CustomInput parentId={props.parentId}
      cancellor={props.cancellor}
      value={props.value}  edit={props.edit}
      submit={props.submit} handleCancel={props.handleCancel}/>
  }

You can then pass this function to the customInput prop

customInput={customInputFunc}

Custom Input Field

With the customInput prop, users ccan create their own custom stylized input field.

Usage

You can create your custom input field by follwing this template.

• The <input> tag needs 2 required props.

  • value = {text} to store the comments and to populate the form while editing a comment.
  • onChange={handleChange} to handle the changing inputs. The handleChange function should setState of the text. For example (ideal case) -> const handleChange = (e) => { setText(e.target.value) }

• The "Post/Submit" <button> tag requires 1 props

  • onClick={() =>submit(cancellor, text, parentId, edit, setText)} This prop can be used as onSubmit by any submitting action.

• The "Cancel" <button> tag requires 1 props

  • onClick={() => handleCancel(cancellor,edit)} This prop can be used by any cancelling action.

Using this template, users can add different styling elements and design their custom GUI for the input field.

import React, {useState} from "react"

const CustomInput=({cancellor,
  parentId,
  value,
  edit,
  submit,
  handleCancel,
  })=>{
    const [text, setText] = useState(value)

    const handleChange = (e) => {
        setText(e.target.value)
      }
    return(  <form>
        <input
          value={text}
          onChange={handleChange}
        />
        <div >
          <button
            onClick={() =>submit(cancellor, text, parentId, edit, setText)}
            type='button'
            disabled={!text}
          >
            Post
          </button>
            <button onClick={() => handleCancel(cancellor,edit)}>
              Cancel
            </button>
        </div>
      </form>)
}

export default CustomInput
