fdgt
fdgt is a mock API for the Twitch Messaging Interface (tmi). Via fdgt, you can connect and test your Twitch bots and other tools with simulated events without having to connect to the real API!
How does it work?
Using fdgt is pretty simple. Instead of pointing to the irc-ws.chat.twitch.tv, you point to to tmi.fdgt.dev. DONE.
Wait seriously?
Yup.
It can't be that simple!
It is, tho. Check out this example with tmi.js.
Connecting to the real tmi
const tmi = require('tmi.js')
const client = new tmi.Client()
client.connect()
Connecting to the fdgt mock tmi
const tmi = require('tmi.js')
const client = new tmi.Client({
connection: { server: 'tmi.fdgt.dev' },
})
client.connect()Simulating events
One of the hardest parts of working with the Twitch chat API is that to test your tool with different payloads, you have to perform the real action that would trigger that event.
Need to trigger a message with bits? You're going to be cheering a lot.
Need to simulate a subscription? I hope you've got deep pockets.
Need to simulate a submysterygift with 10 Tier 3 subscriptions? God help you.
Instead of blowing the wads of cash that you probably don't have, use fdgt! With fdgt, you just have to send the right message to the chat service, and it'll trigger the appropriate event! Here's an example of triggering a message with bits in it, again using tmi.js:
client.say('#TrezyCodes', 'bits')And just like that, fdgt will fire a simulated message with bits attached!
Getting a specific response
Sometimes, the randomized events that fdgt generates just aren't specific enough. Fortunately, fdgt's interface is controlled just like a CLI! If you want to change the username of the person that "triggered" the event, you can pass it with the --username flag!
client.say('#TrezyCodes', 'bits --username alca')...or, say you want to simulate that 10x Tier 3 submysterygift we mentioned earlier:
client.say('#TrezyCodes', 'submysterygift.tier3 --username alca --giftcount 10')For more information on what events are available and what parameters they support, check out the events section.
