## Local Development
|
|
|
|
```bash
|
|
node serve.js
|
|
# Opens at http://localhost:3000
|
|
```
|
|
|
|
The frontend calls the deployed AWS backend — there is no local backend server.
|
|
|

|

|
|
## Deployment
|
|
|
|
The frontend is deployed automatically as part of `cdk deploy` in the backend repo. CDK's `BucketDeployment` syncs this directory to S3 and invalidates the CloudFront cache.
|
|
|
|
```bash
|
|
# From the backend repo:
|
|
cd infra
|
|
GOOGLE_CLIENT_ID=<your-client-id> npx cdk deploy --require-approval never
|
|
```
|
|
|

|

|
## Configuration
|
|
|
|
Edit `config.js` to set:
|
|
|
|
```js
|
|
window.LEDGERFLOW_API_URL = "https://your-api-gateway-url.amazonaws.com";
|
|
window.GOOGLE_CLIENT_ID = "your-client-id.apps.googleusercontent.com";
|
|
```
