SQLITE DATABASE
@capacitor-community/sqlite
Capacitor community plugin for Native and Electron SQLite Databases. In Native databases could be encrypted with SQLCipher
Maintainers
Installation
npm install @capacitor-community/sqlite
npx cap sync
-
On iOS, no further steps are needed.
-
On Android, register the plugin in your main activity:
import com.getcapacitor.community.database.sqlite.CapacitorSQLite;
public class MainActivity extends BridgeActivity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
this.init(
savedInstanceState,
new ArrayList<Class<? extends Plugin>>() {
{
add(CapacitorSQLite.class);
}
}
);
}
}
-
On Electron, go to the Electron folder of YOUR_APPLICATION
npm install --save sqlite3
npm install --save-dev @types/sqlite3
npm install --save-dev electron-rebuild
Modify the Electron package.json file by adding a script "postinstall"
"scripts": {
"electron:start": "electron ./",
"postinstall": "electron-rebuild -f -w sqlite3"
},
Execute the postinstall script
npm run postinstall
Go back in the main folder of your application
Add a script in the index.html file of your application in the body tag
- case databases under
YourApplication/Electron/
<body>
<app-root></app-root>
<script>
try {
if (
process &&
typeof process.versions.electron === 'string' &&
process.versions.hasOwnProperty('electron')
) {
const sqlite3 = require('sqlite3');
const fs = require('fs');
const path = require('path');
window.sqlite3 = sqlite3;
window.fs = fs;
window.path = path;
}
} catch {
console.log("process doesn't exists");
}
</script>
</body>
- case databases under
User/Databases/APP_NAME/
<body>
<app-root></app-root>
<script>
try {
if (
process &&
typeof process.versions.electron === 'string' &&
process.versions.hasOwnProperty('electron')
) {
const sqlite3 = require('sqlite3');
const fs = require('fs');
const path = require('path');
const homeDir = require('os').homedir();
window.sqlite3 = sqlite3;
window.fs = fs;
window.path = path;
window.appName = 'YOUR_APP_NAME';
window.homeDir = homeDir;
}
} catch {
console.log("process doesn't exists");
}
</script>
</body>
Then build YOUR_APPLICATION
npm run build
npx cap copy
npx cap copy web
npx cap open android
npx cap open ios
npx cap open electron
