Mobx Wiretap

The dev tool your mobx and mobx-state-tree app deserve

What's Mobx Wiretap?

Mobx wiretap is an electron app which allows you to inspect your mobx and mobx-state-tree states during development time. This makes debugging easy and fun.

Features

• Mobx
  • Live inspection of observable state
  • Update observable state
  • Listen to action logs
  • Invoke actions
• Mobx state tree
  • Live inspection of state tree
  • View action, snapshot and patch logs
  • Apply snapshots and patches
  • Invoke actions with arguments
  • Record and replay actions

Getting started

1) Download the app

• OS X
• Windows

2) Install the npm module

yarn add mobx-wiretap --dev

3) Inspecting mobx observables

import { observable } from "mobx";
import { wiretap, inspect } from "mobx-wiretap";

// Provide a name as the app name.
wiretap("My awesome app");

const todos = observable([{
   text: "Watch narcos",
   completed: false
}])

// Now you are inspecting todos.
// Changes will reflect in real time in the app.
// First parameter is a required label.
inspect("Todos", todos);

4) Inspecting Mobx-state-tree observables

import { types } from "mobx-state-tree";
// Please note that you have to require from '/mst'.
import { wiretap, inspect } from "mobx-wiretap/mst";

// Provide a name as the app name.
wiretap("My awesome app");

const Todo = types.model("Todo", {
    title: types.string,
    done: false
}).actions(self => ({
    toggle() {
        self.done = !self.done
    }
}));

const todo = Todo.create({
    title: "Get coffee",
    done: false
});

// Now you are inspecting todos.
// Changes will reflect in real time in the app.
// First parameter is a required label.
inspect("Todo", todo);

Sometimes wiretap would not be able to auto-detect the actions from the mst observable you are tracking. In that case, you would be able to pass the action names as the third parameter as follows.

inspect("Todo", todo, ['addTodo']);

5) Inspecting plain object with log()

import { wiretap, log } from "mobx-wiretap";
wiretap("My awesome app");

// Call log
log("CustomObject", {
    question: "Are unicorns real?"
});

Connect to a specific port or a host

Wiretap usually listens on port 4000. If port 4000 is already occupied, wiretap would start listening on a different port. You can find the port in the sidebar.

If wiretap is listening on port other than 4000, you must provide the port when initializing. You could also provide a host.

import { wiretap } from "mobx-wiretap";
wiretap("My awesome app", {
    host: 'http://localhost',
    port: 84585
});

Mobx Wiretap Live (Experimental)

Mobx Wiretap Live is the same inspector but as a hosted app.

App: https://wiretap.debuggable.io/live/

Initialize with the peer id

All you have to do is install mobx-wiretap-remote and initialize your connection with the ID presented to you on https://wiretap.debuggable.io/live/

import { wiretap } from "mobx-wiretap-remote";
wiretap("My awesome app", {
    peerId: "<ID From https://wiretap.debuggable.io/live/>"
});

But if you are worried about sending your data to an unknown service, not to worry, your app data is NOT sent to a centralized server. Instead the app uses WebRTC - peer to peer connection and sends the data directly to the peer. So your app is a peer and the inspector tab is another peer.

FAQ

How does this differ from mobx-dev-tools?

Mobx-dev-tools is an awesome tool to inspect your react app and see how the UI reacts to state changes. Wiretap focuses more on the state itself. You would still need mobx-dev-tools to keep an eye on the react components.

The road ahead

• Support for mobx computed properties.
• Support for mobx-state-tree views.
• Support for react native.
