import React, { Component } from "react";
import ReactQuill from "react-quill";


class Editor extends Component {
  constructor(props) {
    super(props);
    this.state = {
      text: ""
    };
  }

  modules = {
    // #3 Add "image" to the toolbar
    toolbar: [["bold", "italic"]]
  
  };

  formats = [
    "header",
    "bold",
    "italic",
    "underline",
    "strike",
    "blockquote",
    "list",
    "bullet",
    "indent",
    "link"
  ];

  render() {
    return (
      <ReactQuill
        theme="snow"
        modules={this.modules}
        formats={this.formats}
        value={this.state.text}
      >
