VS Code beállítások

Automatikus formázás mentéskor

File/Preferences/Settings => format on save
(restart VS Code)

Környezeti változók

# Windows
ANDROID_HOME=c:\Users\{USERNAME}\AppData\Local\Android\Sdk
PATH > %ANDROID_HOME%\platform-tools %ANDROID_HOME%\emulator
 
# Linux
.bashrc
export ANDROID_HOME=/home/USERNAME/Android/Sdk
export PATH=$ANDROID_HOME/tools:$ANDROID_HOME/platform-tools:$ANDROID_HOME/emulator

React-Native CLI telepítése

npm i -g yarn
npm i -g react-native
# alternatívák
npm i -g react-native-cli
npm i -g @react-native-community/cli

Első lépések

Kezdő projekt létrehozása:

npx react-native init AwesomeTSProject --template react-native-template-typescript
# vagy alternatíva
npx @react-native-community/cli@latest init MyApp --template react-native-template-typescript

Metro indítása

cd AwesomeTSProject
npx react-native start

Cache törlése

npm start -- --reset-cache

Projekt futtatása:

npx react-native run-android

LogCat törlése (az emulátor indítása szükséges)

adb logcat -b all -c 

Hibakeresés VS Code-ban

A .vscode/launch.json ezeket tartalmazza:

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "Debug Android",
            "request": "launch",
            "type": "reactnative",
            "cwd": "${workspaceFolder}",
            "platform": "android"
        },
        {
            "name": "Run Android",
            "request": "launch",
            "type": "reactnative",
            "cwd": "${workspaceFolder}",
            "enableDebug": false,
            "platform": "android"
        }
    ]
}

A Debug Android-ot kell indítani, majd az emulátorban Ctrl+M kombinációt kell nyomni, majd Debug menüpontot válasszuk ki. Ezután a VS Code-ban megáll a töréspontoknál a program futása.

Első alkalmazásom

HTTPRequestsApp github repo-ja.

Telepítés:

git clone https://github.com/pzoli/HTTPRequestsApp.git
cd HTTPRequestsApp
npm install
npx react-native start
npx react-native run-android
