Contributing

Welcome! We're so excited to have you, no matter who you are. To make sure we're creating a safe space for everyone, please check out our Code of Conduct.

Getting setup

Install the necessary node modules and start the development server.

$ npm install
$ npm run dev

Add the development build of the extension to your browser.

1. Navigate to chrome://extensions/ in Chrome
2. Check Developer Mode
3. Click on Load unpacked extension
4. Add command/build

Creating a command

Creating a new command is easy. It requires creating a new command in the commands folder. To demonstrate how this works, let's implement a simple command that opens a new tab to google.com.

Creating the command file

The first thing we need to do is create a new command folder. For the new /google command we are trying to create, let's add a new folder at src/commands/Google and a new file in that folder called src/commands/Google/Google.js. Now, let's make that file export the necessary API to implement a command.

// src/commands/Google/Google.js

import * as types from 'types'

export let match = "google"
export let icon = require("./Google.png")
export let mount = (field, onDone) => {
    return onDone(new types.Redirect({
        url: 'https://google.com',
        target: '_blank'
    })
}

Now that we have our file created, let's walk through what exactly we've exported in this module.

• match - this is the name of the command that a user must type to activate it. So, for this command, a user has to type /google in order to activate the Google command.
• icon - this is a required icon in PNG form that will be used in the quick-select dropdown when a user starts typing a command.
• mount - this is a function which will be called when the command is selected. It is called with two arguments:
  • field - this is a reference to a Field object where the user actually typed the command. For the most part, you won't need to do anything with this: we've created a bunch of easy return types that will let you accomplish almost anything without touching the field in question.
  • onDone - this is the callback the command should call when it's done completing its desired action. This onDone function can be optionally called with a type object that declares a generic result that should either be applied to the field or happen in the browser. To learn more about the different types available, check out the source at src/types/.
  • onInsert - this is a callback that can be used to insert before we call onDone. Like onDone, this should be called with a type object that declares a generic result to be applied to the field or happen in the browser. To learn more about the different types available, check out the source at src/types/.

Enabling the command

Once you've created the folder and exported the required exports, there's nothing else to do! The command should now automatically be loaded into your browser.
