MOCO Browser Extension

Technical Documentation

Development

• run yarn
• run yarn start:chrome or yarn start:firefox (yarn start is an alias for yarn start:chrome)
• load extension into browser:
  • Chrome: visit chrome://extensions and load unpacked extension from build/chrome
  • Firefox: visit about:debugging and load temporary Add-on from build/firefox/manifest.json
• the browser should automatically pick up your changes but from time to time it may be useful to reload the extension
• and most importantly, if you love working with web tech like this, typescript, graphql etc. (👉 we are hiring)

Production Build

• bump version in package.json
• Update CHANGELOG.md
• run yarn build
• The Chrome and Firefox extensions are available as ZIP-files in build/chrome and build/firefox respectively

Install Local Builds

Chrome

• yarn build:chrome
• Visit chrome://extensions
• Enable Developer mode
• Load unpacked and select the build/chrome folder.

Firefox

• yarn build:firefox
• Visit about:debugging
• Click on Load temporary Add-on and select the ZIP-file in build/firefox

Only signed extensions can be permantly installed in Firefox (unless you are using Firefox Developer Edition). To sign the build, proceed as described in Getting started with web-ext.

You can keep the extension settings between builds by providing a stable APPLICATION_ID between builds. You can set an APPLICATION_ID in a file named .env or at build time as follows:

APPLICATION_ID=my-custom-moco-extension@mycompany.com yarn build:firefox

Remote Service Configuration

Remote services are configured in src/js/remoteServices.js.

A remote service is configured as follows:

{
  service_key: {
    name: "service_name",
    host: "https://:subdomain.example.com",
    urlPatterns: [
      ":host:/card/:id",
      [/^:host:\/card\/(\d+), ["subdomain", "id"]],
    ],
    queryParams: {
      projectId: "currentList"
    },
    description: (document, service, { subdomain, id, projectId }) => {
      const title = document
        .querySelector('.title')
        ?.textContent
        ?.trim()
      return `#${id} ${service.key} ${title || ""}`
    },
    projectId: (document, service, { subdomain, id, projectId }) => {
      return projectId
    },
    position: { left: "50%", transform: "translate(-50%)" },
    allowHostOverride: false,
  }
}

Parameter	Description
service_key	string — Unique identifier for the service
service_name	string — Must be one of the registered services trello, jira, asana, wunderlist, github or youtrack
urlPatterns	string | RegEx — A valid URL pattern or regular expression, as described in the url-pattern package. :host: will be replaced with the configured host before applying the pattern (can be configured in the settings if allowHostOverride is true.
queryParams	Object — The object value is the name of the query parameter and the key the property it will available on, e.g. the value of the query parameter currentList will be available under projectId. Matches in urlPatterns have precedence over matches in queryParams.
description	undefined | string | function — The default description of the service. If it is a function, it will receive window.document, the current service and an object with the URL matches as arguments, and the return value set as the default description.
projectId	undefined | string | function — The pre-selected project of the service matching the MOCO project identifier. If it is a function, it will receive window.document, the current service and an object with the URL matches as arguments, and must return the MOCO project identifier or undefined.
projectLabel	undefined | string | function — The pre-selected project of the service matching the MOCO project label. If it is a function, it will receive window.document, the current service and an object with the URL matches as arguments, and must return the MOCO project label or undefined.
position	Object — CSS properties as object styles for position the bubble. Defaults to { right: calc(4rem + 5px)

Adding a Custom Service

1. Fork and clone this repository
2. Add your service to src/removeServices.js, e.g. for self-hosted Jira copy the entry with the key jira and update the urlPatterns:

  "self-hosted-jira": {
    name: "jira",
    urlPatterns: [
      "https\\://jira.my-company.com/secure/RapidBoard.jspa",
      "https\\://jira.my-company.net/browse/:id",
      "https\\://jira.my-company.net/jira/software/projects/:projectId/boards/:board",
      "https\\://jira.my-company.net/jira/software/projects/:projectId/boards/:board/backlog"
    ],
    queryParams: {
      id: "selectedIssue",
      projectId: "projectKey"
    },
    description: (document, service, { id }) => {
      const title =
        document
          .querySelector('[aria-label="Edit Summary"]')
          ?.parentNode?.querySelector("h1")
          ?.textContent?.trim() ||
        document
          .querySelector(".ghx-selected .ghx-summary")
          ?.textContent?.trim()
      return `#${id} ${title || ""}`
    }
  },

3. Build the extension (see Production Build).
4. Install the extension locally (see Install Local Builds).
