Intro screens for Mapeo Mobile for the WCMC ICCA registration app.

These swipe-able introductory screens are designed for the WCMC / ICCA variant of Mapeo Mobile with specific guidance for communities using Mapeo for demarcating ICCA conservation areas.


If you would like to edit these screens, you can set up a local test environment with an example app which allows you to see the introduction on your phone or in a simulator on your desktop, following the instructions below:

1. Install some necessary tools

Install Node 10 LTS or later on your computer.

Install Yarn to manage dependencies.

2. Clone this respository to your computer

Clone this repository to your computer following these instructions (you can clone it using your command line or with Github Desktop).

3. Install the example app dependencies

Open the command line tool on your computer, this will be "Terminal" on a Mac or Linux, or will be "cmd.exe" or "Git Bash" or "Powershell" on Windows.

Change the folder to the folder you just cloned to:


Install all the dependencies

yarn bootstrap

4. Start "Expo" and run the example app

yarn example start

This will open your web browser. Press a to run on a connected Android phone, or i to run in the iOS Simulator (you need to install XCode).

5. Edit the text on the screens

You can edit the text in the file screenDefs.ts and you should see the example app update whenever you save changes.

6. Check your new code is correct

Make sure your code passes TypeScript and ESLint. Run the following to verify:

yarn typescript
yarn lint

To fix formatting errors, run the following:

yarn lint --fix

Commit message convention

We follow the conventional commits specification for our commit messages:

  • fix: bug fixes, e.g. fix crash due to deprecated method.
  • feat: new features, e.g. add new method to the module.
  • refactor: code refactor, e.g. migrate from class components to hooks.
  • docs: changes into documentation, e.g. add usage example for the module..
  • test: adding or updating tests, eg add integration tests using detox.
  • chore: tooling changes, e.g. change CI config.

Our pre-commit hooks verify that your commit message matches this format when committing.

Linting and tests

ESLint, Prettier, TypeScript

We use TypeScript for type checking, ESLint with Prettier for linting and formatting the code, and Jest for testing.

Our pre-commit hooks verify that the linter and tests pass when committing.


The package.json file contains various scripts for common tasks:

  • yarn bootstrap: setup project by installing all dependencies and pods.
  • yarn typescript: type-check files with TypeScript.
  • yarn lint: lint files with ESLint.
  • yarn test: run unit tests with Jest.
  • yarn example start: start the Metro server for the example app.
  • yarn example android: run the example app on Android.
  • yarn example ios: run the example app on iOS.

Sending a pull request

Working on your first pull request? You can learn how from this free series: How to Contribute to an Open Source Project on GitHub.

When you're sending a pull request:

  • Prefer small pull requests focused on one change.
  • Verify that linters and tests are passing.
  • Review the documentation to make sure it looks good.
  • Follow the pull request template when opening a pull request.
  • For pull requests that change the API or implementation, discuss with maintainers first by opening an issue.


npm install @digidem/wcmc-mapeo-mobile-intro


Works best with a navigation library - see the Example

import React from 'react'
import { Text, Button } from 'react'
import { IntroPager, IntroInfo } from '@digidem/wcmc-mapeo-mobile-intro'

// ...

const Intro = () => {
  const [extraInfo, setExtraInfo] = React.useState(null)

  // Use useCallback to avoid unnecessary re-renders
  // This is called with the title and text for the extra info screen
  const handleShowInfo = React.useCallback(({title, text}) => {
    setExtraInfo({title, text})
  }, [])

  // This is called when the user completes the introductions
  const handlePressComplete = React.useCallback(() => {
    // navigate to next page
  }, [])

  return (
        onPressComplete={handlePressComplete} />
      {extraInfo && <View style={{flex: 1}}>
        <IntroInfo markdownText={extraInfo.text}>}
        <Button onPress={() => setExtaInfo(null)}>Close</Button>
