Discover the seamless way to meld Supabase with Electron for crafting engaging desktop applications. This step-by-step guide is designed to simplify and optimize your development journey.
Combining Supabase with Electron takes desktop apps to a whole new level by bringing in Supabase's strong backend capabilities. You get smooth database management and real-time data updates right in your app, plus built-in authentication. To make it happen, set up a Supabase project first, then add the Supabase client library to your Electron app, and be sure to think about how to securely store your API keys. This way, your app stays powerful on the back end while giving users the seamless experience they expect from Electron.
First things first, install Node.js and npm from nodejs.org.
Now, let's create a new Electron project:
```bash
mkdir electron-supabase-app
cd electron-supabase-app
npm init -y
npm install electron --save-dev
```
Next, update the package.json file to add the start script:
```json
"scripts": {
"start": "electron ."
}
```
Create the main.js file to set up your Electron main process:
```javascript
const { app, BrowserWindow } = require('electron');
const path = require('path');
function createWindow() {
const mainWindow = new BrowserWindow({
width: 800,
height: 600,
webPreferences: {
preload: path.join(__dirname, 'preload.js')
}
});
mainWindow.loadFile('index.html');
}
app.whenReady().then(() => {
createWindow();
app.on('activate', () => {
if (BrowserWindow.getAllWindows().length === 0) createWindow();
});
});
app.on('window-all-closed', () => {
if (process.platform !== 'darwin') app.quit();
});
```
index.html file for your application's UI:Create a renderer.js file to interact with Supabase:
```javascript
const { createClient } = require('@supabase/supabase-js');
// Initialize Supabase
const supabaseUrl = 'https://your-supabase-url.supabase.co';
const supabaseKey = 'your-anon-key';
const supabase = createClient(supabaseUrl, supabaseKey);
// Fetch data from your Supabase table
async function fetchData() {
let { data, error } = await supabase
.from('your_table_name')
.select('*');
if (error) {
console.error('Error:', error);
return;
}
const dataContainer = document.getElementById('data');
dataContainer.innerHTML = JSON.stringify(data, null, 2);
}
// Call fetchData function
document.addEventListener('DOMContentLoaded', fetchData);
```
Update or create preload.js to expose necessary APIs to the renderer process:
```javascript
const { contextBridge } = require('electron');
const { createClient } = require('@supabase/supabase-js');
// Initialize Supabase
const supabaseUrl = 'https://your-supabase-url.supabase.co';
const supabaseKey = 'your-anon-key';
const supabase = createClient(supabaseUrl, supabaseKey);
contextBridge.exposeInMainWorld('supabase', {
fetchData: async () => {
let { data, error } = await supabase
.from('your_table_name')
.select('*');
if (error) {
console.error('Error:', error);
return null;
}
return data;
}
});
```
Ensure only necessary APIs are exposed through contextBridge and prevent exposing Node.js internals:
```javascript
contextBridge.exposeInMainWorld('api', {
fetchData: async () => {
return await window.supabase.fetchData();
}
});
```
Update renderer.js accordingly:
```javascript
// Fetch data using exposed API
async function fetchData() {
const data = await window.api.fetchData();
const dataContainer = document.getElementById('data');
dataContainer.innerHTML = JSON.stringify(data, null, 2);
}
document.addEventListener('DOMContentLoaded', fetchData);
```
Start your Electron application:
```bash
npm start
```
Your Electron app should now display data fetched from your Supabase table.
