How to make Embeds which reads the data from the message? - discord

Question

I am trying to make a Discord bot for announcements. I want to create a command which will read the data from the message and convert it into Embedded message.
An example command: !announce Title, Description, Link, Image
const Discord = require('discord.js');
const bot = new Discord.Client();
//listener
bot.on('ready', () => {
bot.user.setGame('Hello!')
});
bot.on('message', (message) => {
if(message.content == 'text') {
const embed = new Discord.RichEmbed()
.setTitle("Title!")
.setDescription("Description")
.setImage("https://i.imgur.com/xxxxxxxx.png")
.setURL("https://google.com")
.addField("Text", true)
//Nope
.setThumbnail("https://i.imgur.com/Rmiwd1j.png")
.setColor(0x00AE86)
.setFooter("Footer", "https://i.imgur.com/xxxxxxxx.png")
.setTimestamp()
/*
* Blank field, useful to create some space.
*/
message.channel.send({embed});
}});
bot.login('token');
I want Embed to be changed based on the text.
How can I do this?

First, you'll need to detect the command: you can use String.startsWith() to detect !announce:
if (message.content.startsWith('!announce')) {...}
Then you'll have to get the other parts of the command by splitting the string: you can separate them with a comma, as you did (title, description, ...), or with whatever character you want (I'll use a comma in my example).
String.slice() will help you get rid of the !announce part, while String.split() will create an Array with the other parts.
This code will generate an embed like this from the command !announce Title, Description, http://example.com/, http://www.hardwarewhore.com/wp-content/uploads/2018/03/dcord.png
client.on("message", message => {
if (message.content.startsWith('!announce')) {
let rest_of_the_string = message.content.slice('!announce'.length); //removes the first part
let array_of_arguments = rest_of_the_string.split(','); //[title, description, link, image]
let embed = new Discord.RichEmbed()
.setTitle(array_of_arguments[0])
.setDescription(array_of_arguments[1])
.setImage(array_of_arguments[3])
.setURL(array_of_arguments[2])
.addField("Text", true)
.setThumbnail("https://i.imgur.com/Rmiwd1j.png")
.setColor(0x00AE86)
.setFooter("Footer", array_of_arguments[3])
.setTimestamp();
message.channel.send({ embed });
}
});
I suggest using the text instead of the description and remind that the second argument of the .addField() is the text, not the inline value
