# Waku Browser Tests
This project provides a system for testing the Waku SDK in a browser environment.
## Architecture
The system consists of:
1. **Headless Web App**: A simple web application (in the `@waku/headless-tests` package) that loads the Waku SDK and exposes shared API functions.
2. **Express Server**: A server that communicates with the headless app using Playwright.
3. **Shared API**: TypeScript functions shared between the server and web app.
## Setup
1. Install dependencies:
```bash
# Install main dependencies
npm install
# Install headless app dependencies
cd ../headless-tests
npm install
cd ../browser-tests
```
2. Build the application:
```bash
npm run build
```
This will:
- Build the headless web app using webpack
- Compile the TypeScript server code
## Running
Start the server with:
```bash
npm run start:server
```
This will:
1. Serve the headless app on port 8080
2. Start a headless browser to load the app
3. Expose API endpoints to interact with Waku
## API Endpoints
- `GET /info`: Get information about the Waku node
- `GET /debug/v1/info`: Get debug information from the Waku node
- `POST /push`: Push a message to the Waku network (legacy)
- `POST /lightpush/v1/message`: Push a message to the Waku network (Waku REST API compatible)
- `POST /admin/v1/create-node`: Create a new Waku node (requires networkConfig)
- `POST /admin/v1/start-node`: Start the Waku node
- `POST /admin/v1/stop-node`: Stop the Waku node
- `POST /admin/v1/peers`: Dial to specified peers (Waku REST API compatible)
- `GET /filter/v2/messages/:contentTopic`: Subscribe to messages on a specific content topic using Server-Sent Events (Waku REST API compatible)
- `GET /filter/v1/messages/:contentTopic`: Retrieve stored messages from a content topic (Waku REST API compatible)
### Example: Pushing a message with the legacy endpoint
```bash
curl -X POST http://localhost:3000/push \
-H "Content-Type: application/json" \
-d '{"contentTopic": "/toy-chat/2/huilong/proto", "payload": [1, 2, 3]}'
```
### Example: Pushing a message with the Waku REST API compatible endpoint
```bash
curl -X POST http://localhost:3000/lightpush/v1/message \
-H "Content-Type: application/json" \
-d '{
"pubsubTopic": "/waku/2/rs/0/0",
"message": {
"payload": "SGVsbG8sIFdha3Uh",
"contentTopic": "/toy-chat/2/huilong/proto",
"timestamp": 1712135330213797632
}
}'
```
### Example: Executing a function
```bash
curl -X POST http://localhost:3000/execute \
-H "Content-Type: application/json" \
-d '{"functionName": "getPeerInfo", "params": []}'
```
### Example: Creating a Waku node
```bash
curl -X POST http://localhost:3000/admin/v1/create-node \
-H "Content-Type: application/json" \
-d '{
"defaultBootstrap": true,
"networkConfig": {
"clusterId": 1,
"shards": [0, 1]
}
}'
```
### Example: Starting and stopping a Waku node
```bash
# Start the node
curl -X POST http://localhost:3000/admin/v1/start-node
# Stop the node
curl -X POST http://localhost:3000/admin/v1/stop-node
```
### Example: Dialing to specific peers with the Waku REST API compatible endpoint
```bash
curl -X POST http://localhost:3000/admin/v1/peers \
-H "Content-Type: application/json" \
-d '{
"peerMultiaddrs": [
"/ip4/127.0.0.1/tcp/8000/p2p/16Uiu2HAm4v8KuHUH6Cwz3upPeQbkyxQJsFGPdt7kHtkN8F79QiE6"]
]
}'
```
### Example: Dialing to specific peers with the execute endpoint
```bash
curl -X POST http://localhost:3000/execute \
-H "Content-Type: application/json" \
-d '{
"functionName": "dialPeers",
"params": [
["/ip4/127.0.0.1/tcp/8000/p2p/16Uiu2HAm4v8KuHUH6Cwz3upPeQbkyxQJsFGPdt7kHtkN8F79QiE6"]
]
}'
```
### Example: Subscribing to a content topic with the filter endpoint
```bash
# Open a persistent connection to receive messages as Server-Sent Events
curl -N http://localhost:3000/filter/v2/messages/%2Ftoy-chat%2F2%2Fhuilong%2Fproto
# You can also specify clustering options
curl -N "http://localhost:3000/filter/v2/messages/%2Ftoy-chat%2F2%2Fhuilong%2Fproto?clusterId=0&shard=0"
```
### Example: Retrieving stored messages from a content topic
```bash
# Get the most recent 20 messages
curl http://localhost:3000/filter/v1/messages/%2Ftoy-chat%2F2%2Fhuilong%2Fproto
# Get messages with pagination and time filtering
curl "http://localhost:3000/filter/v1/messages/%2Ftoy-chat%2F2%2Fhuilong%2Fproto?pageSize=10&startTime=1712000000000&endTime=1713000000000&ascending=true"
```
## Extending
To add new functionality:
1. Add your function to `src/api/shared.ts`
2. Add your function to the `API` object in `src/api/shared.ts`
3. Use it via the server endpoints
### Example: Dialing to specific peers
```bash
curl -X POST http://localhost:3000/execute \
-H "Content-Type: application/json" \
-d '{
"functionName": "dialPeers",
"params": [
["/ip4/127.0.0.1/tcp/8000/p2p/16Uiu2HAm4v8KuHUH6Cwz3upPeQbkyxQJsFGPdt7kHtkN8F79QiE6"]
]
}'
```

# Waku Headless Tests
This package contains a minimal browser application used for testing the Waku SDK in a browser environment. It is used by the browser-tests package to run end-to-end tests on the SDK.
## Usage
### Build the app
```bash
npm run build
```
### Start the app
```bash
npm start
```
This will start a server on port 8080 by default.
## Integration with browser-tests
This package is designed to be used with the browser-tests package to run end-to-end tests on the SDK. It exposes the Waku API via a global object in the browser.
