22## Quick Start
23 
24### Install EAS CLI
25 
26```bash
27npm install -g eas-cli
28eas login
29```
30 
31### Initialize EAS
32 
33```bash
34npx eas-cli@latest init
35```
36 
37This creates `eas.json` with build profiles.
38 
39## Build Commands
40 
41### Production Builds
42 
43```bash
44# iOS App Store build
45npx eas-cli@latest build -p ios --profile production
46 
47# Android Play Store build
48npx eas-cli@latest build -p android --profile production
49 
50# Both platforms
51npx eas-cli@latest build --profile production
52```
53 
54### Submit to Stores
55 
56```bash
57# iOS: Build and submit to App Store Connect
58npx eas-cli@latest build -p ios --profile production --submit
59 
60# Android: Build and submit to Play Store
61npx eas-cli@latest build -p android --profile production --submit
62 
63# Shortcut for iOS TestFlight
64npx testflight
65```
66 
67## Web Deployment
68 
69Deploy web apps using EAS Hosting:
70 
71```bash
72# Deploy to production
73npx expo export -p web
74npx eas-cli@latest deploy --prod
75 
76# Deploy PR preview
77npx eas-cli@latest deploy
78```
79 
80## EAS Configuration
81 
82Standard `eas.json` for production deployments:
83 
84```json
85{
86  "cli": {
87    "version": ">= 16.0.1",
88    "appVersionSource": "remote"
89  },
90  "build": {
91    "production": {
92      "autoIncrement": true,
93      "ios": {
94        "resourceClass": "m-medium"
95      }
96    },
97    "development": {
98      "developmentClient": true,
99      "distribution": "internal"
100    }
101  },
102  "submit": {
103    "production": {
104      "ios": {
105        "appleId": "[email protected]",
106        "ascAppId": "1234567890"
107      },
108      "android": {
109        "serviceAccountKeyPath": "./google-service-account.json",
110        "track": "internal"
111      }
112    }
113  }
114}
115```
116 
117## Platform-Specific Guides
118 
119### iOS
120 
121- Use `npx testflight` for quick TestFlight submissions
122- Configure Apple credentials via `eas credentials`
123- See ./reference/testflight.md for credential setup
124- See ./reference/ios-app-store.md for App Store submission
125 
126### Android
127 
128- Set up Google Play Console service account
129- Configure tracks: internal → closed → open → production
130- See ./reference/play-store.md for detailed setup
131 
132### Web
133 
134- EAS Hosting provides preview URLs for PRs
135- Production deploys to your custom domain
136- See ./reference/workflows.md for CI/CD automation
137 
138## Automated Deployments
139 
140Use EAS Workflows for CI/CD:
141 
142```yaml
143# .eas/workflows/release.yml
144name: Release
145 
146on:
147  push:
148    branches: [main]
149 
150jobs:
151  build-ios:
152    type: build
153    params:
154      platform: ios
155      profile: production
156 
157  submit-ios:
158    type: submit
159    needs: [build-ios]
160    params:
161      platform: ios
162      profile: production
163```
164 
165See ./reference/workflows.md for more workflow examples.
166 
167## Version Management
168 
169EAS manages version numbers automatically with `appVersionSource: "remote"`:
170 
171```bash
172# Check current versions
173eas build:version:get
174 
175# Manually set version
176eas build:version:set -p ios --build-number 42
177```
178 
179## Monitoring
180 
181```bash
182# List recent builds
183eas build:list
184 
185# Check build status
186eas build:view
187 
188# View submission status
189eas submit:list
190```
