bot-util

bot-util is a package that makes it easier to post and automate posting to Facebook pages.

  • Add Facebook pages by ID or link
  • Add an app token with manage_pages and publish_pages permissions.
  • Automate your posting!

Installation

$ npm install --save bot-util

Quick Start

let bot_util = require('bot-util');

// using Promises
bot_util.facebook.AddPage(PAGE_ID/PAGE_URL, ACCESSTOKEN)
  .then(id => {
    bot_util.facebook.pages[id].Post({
      type: 'text',
      message: 'This is my first post!'
    }).then(res => {
      console.log(`Posted. Post ID: ${res.id}`);
    }).catch(err => {
      console.log(err);
    });
  })
  .catch(err => {
    throw err;
  })

// using await
async function setupPage(){
  let id = await bot_util.facebook.AddPage(PAGE_ID/PAGE_URL, ACCESSTOKEN);
  let post = await bot_util.facebook.pages[id].Post({
    type: 'text',
    message: 'This is my first post!'
  });
  console.log(`Posted. Post ID: ${post.id}`);
}

setupPage();

If you have multiple pages that you want to add all at once, you can use AddPages(pages: array), the array containing objects that look like { id: PAGEID, token: TOKEN }

bot_util.facebook.AddPages([
    { id: PAGEID1, token: TOKEN1 },
    { id: PAGEID2, accessToken: TOKEN2 },
    { id: PAGEID3, token: TOKEN3, name: 'Page name' }
]).then(ids => {
    console.log('pages added');
})

Posting

A post has a type of either text, image, or video.

Make sure you already added the page before using its ID

Posting text

bot_util.facebook.pages[id].Post({
  type: 'text',
  message: 'This is my first post!'
}).then(res => {
  console.log(`Posted. Post ID: ${res.id}`);
}).catch(err => console.log(err));

Posting an image

When posting an image or a video, the 'source' property of the object can either be a path or a ReadStream.

The properties message, caption and description can be used interchangeably for posts.

bot_util.facebook.pages[id].Post({
  type: 'image',
  source: 'path/to/image.png',
  caption: 'this is an image!' // optional
}).then(res => {
  console.log(`post id: ${res.id}`);
}).catch(err => console.log(err));

Posting video

bot_util.facebook.pages[id].Post({
  type: 'video',
  source: 'path/to/video.mp4',
  title: 'Video Title', // optional
  description: 'this is a video!' // optional
}).then(res => {
  console.log(`post id: ${res.id}`);
}).catch(err => console.log(err));

Commenting

A comment can also contain a source property that is used to comment pictures. The 'source' property can be either a path or a ReadStream.

The object_id is the ID of the object upon which the comment will be made.

bot_util.facebook.pages[id].Comment({
  on: object_id,
  message: 'This is a comment!',
  source: 'path/to/image.png' // optional
}).then(res => {
  console.log(`comment id: ${res.id}`);
}).catch(err => console.log(err));

Getters

bot-util can also be used to get posts, comments, and reactions.

All getters accept an options object. Currently the only parameter the options object supports is fields which specifies which fields should be retrieved from the Facebook API.

The fields parameter can either be a string (with the fields separated by ","), or an array of strings example:

bot_util.facebook.pages[id].get.posts.all({fields: ['id', 'message', 'type']})
.then(res => {
  //every post in `res` will have their id, message and type [link, status, photo, video, offer]
}).catch(err => console.log(err));

or

bot_util.facebook.pages[id].get.posts.all({fields: 'id, message, created_time'})
.then(res => {
  //every post in `res` will have their id, message and creation time
}).catch(err => console.log(err));

Posts

all

all(options: object)

bot_util.facebook.pages[id].get.posts.all()
.then(res => {
  console.log(res);
}).catch(err => console.log(err));

latest

latest() (without any parameter) returns the latest post made on the specified page.

bot_util.facebook.pages[id].get.posts.latest()
.then(res => {
  console.log(res);
}).catch(err => console.log(err));

latest(n: number, options: object) returns the latest n posts made on the specified page.

bot_util.facebook.pages[id].get.posts.latest(5)
.then(res => {
  //the last 5 posts
  console.log(res);
}).catch(err => console.log(err));

range

range(start_date: Date, end_date: Date, options: object) returns all posts published between the two dates

let now = new Date();
let aWeekAgo = new Date(Date.now() - (7 * 24 * 60 * 60 * 1000));
bot_util.facebook.pages[id].get.posts.range(aWeekAgo, now)
.then(posts => {
  //all posts published in the last 7 days
  console.log(posts);
}).catch(err => console.log(err));

Comments

comments(object_id: string, options: object) The object_id is the ID of the object that we are retrieving the comments of.

bot_util.facebook.pages[id].get.comments(object_id).then(comments => {
  console.log(comments);
}).catch(err => console.log(err));

Reactions

reactions(object_id: string, options: object) The object_id is the ID of the object that we are retrieving the reactions of.

bot_util.facebook.pages[id].get.reactions(object_id).then(reactions => {
  console.log(reactions);
}).catch(err => console.log(err));

Scheduling Posts

bot_util.facebook.pages[page_id].SchedulePost(recurrenceRule, func)

'func' gets called everytime node-schedule fires.

onPosted(res) is a callback function that gets called everytime that post is made and is passed an object containing the post id and, if it's the case, comment id.

For more info on the 0 */30 * * * * pattern you can check out the node-schedule package because they have a much better explanation than I could give! For now, 0 */30 * * * * means every 30 minutes, 0 0 * * * * means every hour, 0 0 */2 * * * means every 2 hours.

Sync

bot_util.facebook.pages[id].SchedulePost('0 */30 * * * *', () => {
    //do sync stuff here, then return the Post object
    return {
        type: 'text', //required [text, image, video]
        caption: 'Scheduled posts! woo!', // REQUIRED [caption/message/description]
        source: 'path/to/file', // REQUIRED IF TYPE IS image OR video [path, ReadStream]
        comment: { // optional
            message: 'this is a comment!', // required
            source: 'path/to/image/image.png' //OPTIONAL [path, ReadStream]
        }, // OPTIONAL
        onPosted: res => {
            console.log(`post id: ${res.id}, comment id: ${res.comment_id}`);
        }
    }
}).then(job => {
    //the node-schedule job gets returned
}).catch(err => {
    throw err;
})

Async

In the following snippet of code, doAsyncStuff() is a hypothetical asynchronous function that is resolved at some unknown time in the future.

bot_util.facebook.pages[id].SchedulePost('0 */30 * * * *', () => {
    return new Promise((resolve, reject) => {
        //do async stuff here, then resolve the Post object
        doAsyncStuff().then(() => {
            resolve({
                type: 'text', //required [text, image, video]
                caption: 'Scheduled posts! woo!', // REQUIRED [caption/message/description]
                source: 'path/to/file', // REQUIRED IF TYPE IS image OR video [path, ReadStream]
                comment: { // optional
                    message: 'this is a comment!', // required
                    source: 'path/to/image/image.png' //OPTIONAL [path, ReadStream]
                }, // OPTIONAL
                onPosted: res => {
                    console.log(`post id: ${res.id}, comment id: ${res.comment_id}`);
                }
            })
        })
    })
}).then(job => {
    //the node-schedule job gets returned
}).catch(err => {
    throw err;
});

If these wrappers don't satisfy your needs, you still have access to the whole FB api by using bot_util.facebook.api
