# Puppeteer(Chrome headless node API) based web page renderer
[Puppeteer](https://github.com/GoogleChrome/puppeteer) (Chrome headless node API) based web page renderer.
Useful server side rendering through proxy. Outputs HTML, PDF and screenshots as PNG.
## Requirements
You can run Chromium or docker.
## Getting Started
### Start server using docker (If you can not run Chromium and installed docker)
```bash
docker run -d --name renderer -p 8080:3000 ghcr.io/zenato/puppeteer-renderer:latest
```
### Local (git clone)
`pnpm install`
#### Start server (If you can run Chromium)
`pnpm dev`
(service port: 3000)
#### Locally build the image
```bash
docker build . --file ./Dockerfile --tag local/puppeteer-renderer --build-arg SCOPE=puppeteer-renderer
```
docker run -d --name renderer -p 8080:3000 local/puppeteer-renderer
```
### Test on your browser
Input url `http://localhost:{port}/{html|pdf|screenshot}?url=https://www.google.com`
If you can see html code, server works fine.
### Puppeteer customization
When starting `pnpm {dev|start}` or docker container you can customize puppeteer using environment variables.
- `IGNORE_HTTPS_ERRORS=true` - Ignores HTTPS errors
- `PUPPETEER_ARGS='--host-rules=MAP localhost yourproxy'` - Ads additional args that will be passed to puppeteer. Supports multiple arguments.
## Integration with existing service.
If you have active service, set proxy configuration with middleware.
See [puppeteer-renderer-middleware](packages/middleware/README.md) for express.
```ts
import express from 'express'
import renderer from 'puppeteer-renderer-middleware'
const app = express()
app.use('/render-proxy', renderer({
url: 'http://installed-your-puppeteer-renderer-url',
// userAgentPattern: /My-Custom-Agent/i,
// excludeUrlPattern: /*.html$/i
// timeout: 30 * 1000,
}));
// your service logics..
app.listen(8080);
```

Generated PDFs are returned with a `Content-disposition` header requesting the browser to download the file instead of showing it.
The file name is generated from the URL rendered:
| URL | Filename |

| `https://www.example.com/` | `www.example.com.pdf` |
| `https://www.example.com:80/` | `www.example.com.pdf` |
| `https://www.example.com/resource` | `resource.pdf` |
| `https://www.example.com/resource.extension` | `resource.pdf` |
| `https://www.example.com/path/` | `path.pdf` |
| `https://www.example.com/path/to/` | `pathto.pdf` |
