📚Documentation	📕Bugs

Installation

npm i simple-chat-storage
or
yarn add simple-chat-storage

Most usefull features (There is both a JSON storage and a sqlite storage)

addmessage(user, message, time(optional)) - adds message to chat
erase() - erases the storage
deletemessage(index) - deletes the message by index(storage.messages[index])

Most usefull features (sqlite)

new SqliteChatStorage(name, dbpath, length)

Name	Type	Default	Description
name	string		name of table in sqlite database
dbpath	string	chat.db	path to sqlite database
length	integer/false	false	number of stored messages

prepare() - Preparing and initializing the table and returnings a promise
deletemessage(id) - deletes the message by id
replacemessage(id, message) - replaces the message by id
delete(where) - SQL deleter
select(what, where(optional)).then((row)=>{}).catch((err)=>{}) - SQL selector
getBdId(index) - returns id of message from index (storage.messages[index].id)

Example

const chat = require("simple-chat-storage").sqlite;
const test = new chat("test", "chat.db", 30);
test.prepare().then(()=>{
	test.addmessage("Dr. Who", "Fez!").then(()=>{
		console.log(test.messages[0]);
		test.replacemessage(test.getBdId(0), "Hooray, I can edit messages.")
		.then(()=>{
			console.log(test.messages[0]);
		});
	});
});

Most usefull features (JSON)

Faster than sqlite, but does not have SQL functions

new JsonChatStorage(name, length, dir)

Name	Type	Default	Description
name	string		name of JSON storage
length	integer/false	false	number of stored messages
dir	string	./chats	folder for storing all json storages
meta	Object/none		metadata for JSON storage

deletelastmessage(user) - Deletes a last message of user

Example

let chat = require("simple-chat-storage").JSON;
let test = new chat("test");
test.addmessage("Dr. Who", "Fez!");
console.log(test.messages);
