Tweedentity.js

A library to integrate Tweedentity in any decentralized app.

Getting started

To use tweedentity:

npm i tweedentity --save

Client

Example

Instantiate the client:

const tweedentityClient = require('tweedentity/Client')
const tClient = new tweedentityClient(web3js)

API

load()

Loads the contracts. It must be executed after instantiating the object and before any other commands. Example:

tClient.load()
.then(() => {
  console.log(tClient.contracts.stores.twitter.address)
})

on Ropsten, it should print 0x0de9ccba310161c06ae194f65965c309af167913

getIdentities(address, reload)

Gets the identities associated to address. The first time it is executed, it saves the results in the property profiles so that in the future it can read quickly from that. The param reload forces the reload of the data from the blockchain.

tClient.getIdentities('0x93a5b8fc1a951894361c4c35523e23ba6bf073b7')
.then(result => {
   console.log(result.twitter)
})

Should print 946957110411005953.

If there isn't any tweedentity set for the specified address, it returns an empty object.

When you have the twitter userId, to recover the profile associated with it you can either use the Twitter API or parse the data using the Server component (see below in the Server section).

getIdentity(app, address)

Gets the identities associated to address and the specified app. The first parameter can be the nickname of the app, for example twitter, or its id, i.e. 1 for twitter. If the app is not supported it throws new Error('App not supported').

tClient.getIdentity('twitter', '0x93a5b8fc1a951894361c4c35523e23ba6bf073b7')
.then(result => {
   console.log(result)
})

Should print 946957110411005953. Alternatively, it can be called as

tClient.getIdentity(1, '0x93a5b8fc1a951894361c4c35523e23ba6bf073b7')
...

getFullIdentities__(address)

Returns the same of getIdentities but with the full TID. In the example above, it should return for twitter 1/946957110411005953, where 1 is the twitter appId in Tweedentity.

getFullIdentity(appNickname, address)__

Returns the same of getIdentity but with the full TID.

totalIdentities()

Returns a summary of the total of set tweedentities.

tClient.totalIdentities()
.then(result) {
  console.log(result)
})

Should print something like

{total: 200, twitter: 140, reddit: 60}

totalIdentityByApp(app)

Returns the total number of tweedentities set for the specified app.

tClient.totalIdentitiesByApp('twitter')
.then(result) {
  console.log(result)
})

In line with the previous example, it should print 140.

Static methods

fullify(id)

Returns the TID.

console.log(tweedentityClient.fullify('twitter','87237464536')

Should print 1/87237464536

isSupported(app)

Returns true if the app is supported.

normalizeApp(app)

Returns the appNickname, despite if app is already a nickname or is an id.

appByTID(tid)

Returns the appNickname of a TID.

console.log(tweedentityClient.appByTID('1/78746563'))

Should print twitter

Server

Versions starting from 0.2.0 are not compatible with previous 0.1.x versions.

When you have the tweedentities associated to a wallet you can retrieve the user profile using the app API, for example, the Twitter API. Alternatively, you can use server-side the Tweedentity API to parse the data from the web.

Supposing you are using Express, to get the basic profile about a Reddit tweedentity (userId, username, name and avatar), you could have something like:

const tServer = require('tweedentity').Server

router.post('/data/:webApp', jsonParser, function (req, res, next) {

  const webApp = req.params.webApp
  const provider = new Provider()

  tServer.getDataByTID(webApp, req.body.userId)
    .then(result => {
      res.status(200).json(result)
    })
    .catch(err => {
      res.status(200).json({error: err.message})
    })
})

This should return something like:

{
    "userId": "1ys6ez",
    "username": "mary908345",
    "name": "Bloody Mary",
    "avatar": "https://s.redditmedia....png?...."
}

Or, if the account does not exists:

{
  "error": "Not found"
}
