Expo Release Channels

Expo just released (11/17/2017) beta support for Release Channels

We strongly recommend moving forward with Expo's official supported implementation!

About

Right now Expo doesn't support different deploy environments like staging and production. This is a simple tool to help mimic that environment by creating a copy of your app.json and adding a suffix to stuff like name and slug.

Expo is working on supporting their own deployment environments. As soon as its released I'll update the repo to take you there instead

Orchard uses this on an daily basis to deploy their different environments

Instructions

• exp-deploy requires a config folder with a copy of app.json. Create the following:
  • config/exp-development.json
  • config/exp-production.json
• If you'd like to store environment variables, create a config object next to expo within app.json:

  "config": {
    "apiUrl": "https://api.mysite.com",
    "sentryApiKey": "xyz"
  },
  "expo": {
    "name": "MyAppName",
    "privacy": "unlisted",
    "slug": "my-app-name",
    "sdkVersion": "1.0.0",
    "scheme": "my-app-name",
    "version": "1.0.0",
  }

• Running exp-deploy --production will now do the following:
  • copy config/exp-production.json over into app.json
  • run exp publish
  • reset app.json to its previous state

yarn global add exp-deploy-cli

npm install -g exp-deploy-cli

Usage

Usage: exp-deploy [command]

Commands:
  config                   Initial Config Setup

Options:
  --help  Show help        [boolean]

Examples:
  exp-deploy config
  exp-deploy --env production
  exp-deploy --env staging

Using Config Variables in your app

Since Expo doesn't give you access to Config via Constants.manifest, you can import the json file directly:

import App from './app.json'

const API_URL = App.config.apiUrl

Future Api

• exp config
• exp deploy
• exp releases
• exp rollback

Philosophy / Idea

• exp doesn't support dev. vs prod environments so lets try and make it work on our own
• create a config folder and place exp-development.json and exp-production.json
• within your app.json create a config object to store your api keys, etc. in
• run exp-deploy config which will:
  • run interactive shell
  • check for config folder. If doesn't exist, create it
  • copy over app.json into exp-development.json and exp-production.json
  • ask user for any specific api keys they would like to separate
• run exp-deploy --production which will:
  • check whether config/exp-production.json exists
  • copy it over into your main app.json
  • bumps the version number (or npm version patch) by default
  • save the version number, commit it including creating a tag
  • save the release into a releases.json file
• run exp-deploy releases which will:
  • look up releases.json with every released version
    • ties in git tag / release to what's been deployed
• run exp-deploy rollback which will:
  • look into releases.json and asks you interactively to choose a version to roll back to
  • will check out the git tag and roll back your deploy to that specific version
