express-comment Simple Article Post/Comment Management Middleware

express-comment is a middleware bundled with frontend API utilities that allows you to create a simple yet highly usable post/comment system with minimal code.

Condition

This package is under active development, and is just entering its alpha stage. The API may change with new features added in the future.

How to use

Install express-comment-frontend as frontend API and /lib/api.md for details, and /example/* for examples of backend use. In general, you can simply mount the middleware on a path with minimal configuration, and use /lib/frontend predefined API for simple query and update.

Demo

Front-end API

// frontend code, using lib/index.js of express-comment-frontend
let comment = commentFactory(window, '/api/express-comment/mounted/path');

// If you use React/Node instead, you can likely to be able to simply (not yet tested)
import commentFactory from 'express-comment-frontend';
let comment = commentFactory(window, '/api/express-comment/mounted/path');

// begin:

let commentID;
let replyID;

// Callback styled
comment
  .comment('Hello world')
  .by('Kevin')
  .on('Article-01')
  .fire((err, id) => {
    if (err) throw err;
    commentID = id;
  });

// Promise styled
comment
  .reply('This is a reply!')
  .by('Tom')
  .to(commentID)
  .fire()
  .then((id) => replyID = id)
  .catch((err) => console.log('ERROR!', err));

comment
  .update('I want this as reply body instead!')
  .of(replyID)
  .fire();

comment
  .findAll(true) // true if you want to get all replies to the comment found, will be accessible at entry[i].reply
  .of(commentID)
  .fire()
  .then(console.log);

// find root comments on an article
comment
  .findRootAll() // true if you want to get all replies to the comment found, will be accessible at entry[i].reply
  .on('Article-01')
  .fire()
  .then(console.log);

// Delete!
comment
  .delete()
  .by('Tom')
  .fire()
  .then(() => console.log('Sadly, Tom\'s replies are deleted...'))
  .catch((err) => console.log('ERROR!', err));

comment
  .delete()
  .of(commentID)
  .fire()
  .then(() => console.log('Sadly, Kevin\'s first comment is deleted...'))
  .catch((err) => console.log('ERROR!', err));

Back-end API

const express = require('express');
const bodyParser = require('body-parser');
const app = express();
const comment = require('express-comment');
const drivers = comment.drivers;

// General settings
const ecSettings = {}

// with MongoDB (Mongo Native Client)
const mongo_config = {
  /* ... */
  // see /lib/db/mongo/README.md
};
app.use('/api/express-comment/mounted/path', bodyParser.urlencoded({ extended: true }), comment(drivers.mongo(mongo_config), ecSettings));

// or if with Sequelize.js (supporting MySQL, PostgreSQL, SQLite, etc.)
const sequelize_config = {
  database: 'ec',
  username: 'root',
  password: '',
  settings: {
    /* Sequelize config settings, check Sequelize docs about config settings. */
    host: 'localhost',
    dialect: 'mysql',

    pool: {
      max: 5,
      min: 0,
      acquire: 30000,
      idle: 10000
    },
  }
}
app.use('/path/middleware/mounted', bodyParser.urlencoded({ extended: true }), comment(drivers.sql(sequelize_config), ecSettings));

/* ... */

// You are good to go!
