Meatspace actions

Initialize

var Meatspace = require('meatspace-leveldb');

var meat = new Meatspace({
  fullName: 'Edna Piranha',
  username: 'ednapiranha',
  postUrl: 'http://meatspace.generalgoods.net/recent.json',
  db: './db',
  limit: 10,
  keyId: ':1'
});

db is the path where your leveldb database is located.

keyId is an optional value you can set to assign a key to a particular user id or identifier. If you are not running this for multiple users, skip changing this option (optional).

limit is the number of records you want returned per page - defaults to 10 (optional).

Create

var message = {
  content: {
    message: 'some message',
    urls: [
      {
        title: 'some url',
        url: 'http://some.url.com'
      }
    ]
  },
  meta: {
    location: '37.3882807, -122.0828559',
    isPrivate: false
  }
};

meat.create(message, function (err, message) {
  if (!err) {
    console.log(message);
  }
});

Edit / Update

meat.get(1, function (err, m) {
  if (!err) {
    m.content.message = 'new updated message';
    meat.update(m, function (err, m) {
      if (!err) {
        console.log(m)
      }
    });
  }
});

Delete

meat.get(1, function (err, message) {
  if (!err) {
    meat.del(message.id, function (err, status) {
      if (status) {
        console.log('deleted!')
      }
    });
  }
});

Get all public and private

The default limit is set to 10. You can change this by setting meat.limit = 15 as an example.

First argument 0 is the page from where you want to get messages.

meat.getAll(0, function (err, messages) {
  if (!err) {
    console.log(messages);
  }
});

Share all recent public

The default limit is set to 10. You can change this by setting meat.limit = 15 as an example.

First argument 0 is the page from where you want to get messages.

meat.shareRecent(0, function (err, messages) {
  if (!err) {
    console.log(messages);
  }
});

Share a single public message that you authored

meat.shareOne(1, function (err, message) {
  if (!err) {
    console.log(message);
  }
});

Share a public message that someone else authored

Assumptions: externalMessage is a meatspace message from a separate server.

meat.share(externalMessage, meat.postUrl, function (err, message) {
  if (!err) {
    console.log(message);
  }
});

Get all subscriptions

meat.getSubscriptions(function (err, subscriptoins) {
  if (!err) {
    console.log(subscriptions);
  }
});

Subscribe to someone else's meatspace

meat.subscribe('http://some.other.url/recent.json', function (err, url) {
  if (!err) {
    console.log(url);
  }
});

Unsubscribe to a meatspace

meat.unsubscribe('http://some.other.url/recent.json', function (err, status) {
  if (!err) {
    console.log(status);
  }
});

Get most recent micrologs from a subscribed meatspace

meat.getSubscriptionRecent('http://some.other.url/recent.json', function (err, messages) {
  if (!err) {
    console.log(messages);
  }
});

Delete the database

meat.flush();

Important notes and tips

• Your posts will not be automatically protected from XSS so that is up to you to handle if you decide to use this in a web app. If you want to work from an existing example, feel free to fork generaltoast and test the leveldb branch.
• If you want to back up your messages in a secondary database such as PostgreSQL or MySQL, just add this after a successfull callback in meat.add, meat.del, etc.
