centrifuge VS gotenberg

BTW, Centrifugo is based on https://github.com/centrifugal/centrifuge Go library which may provide much more control and flexibility for Gophers than a standalone server and can be embedded to any Go app leveraging all Centrifugo client SDKs.

There are libraries which provide more advanced APIs for creating real-time applications, for example https://github.com/centrifugal/centrifuge

Yes, but there are two excelent libs for golang websockets - https://github.com/gobwas/ws - https://github.com/centrifugal/centrifuge

What https://github.com/centrifugal/centrifuge does:

Have you considered https://github.com/centrifugal/centrifuge? It also uses Gorilla WebSocket for WebSocket transport at the moment – but it's hidden inside and may be replaced if needed since Transport interface is pluggable. It's more heavyweight though than both Melody and Gorilla WebSocket but provides much more functionality out-of-the-box.

Not a Socket.IO compatible but maybe you will find it useful/interesting: https://github.com/centrifugal/centrifuge

Thanks! BTW, Centrifugo's core is based on https://github.com/centrifugal/centrifuge Go library - which theoretically can be more flexible and extensible solution for Go developers than Centrifugo server since server dictates some auth/permission/channel/api rules.

Hello, +1 to WebSockets. If you need to choose WS library – go with https://github.com/gorilla/websocket or https://github.com/gobwas/ws. You can also look at Centrifugo server (https://centrifugal.dev/, supports WebSocket, SockJS bidi transports, also EventSource, HTTP-streaming, GRPC unidirectional transports and many builtin features) or https://github.com/centrifugal/centrifuge Go library.

Use a server-side headless browser such as puppeteer to convert the HTML to PDF. This is the most reliable free option, but requires a server. If you need to use it in production, we recommend you use Gotenberg.

We're using Gotenberg[1] to convert a rendered web page (with Elixir/Phoenix, in our case) to PDF. Works like a charm and we can use our existing frontend code/styling (including SVG graph generators) which is a huge bonus.

If you also want to convert Markdown or LibreOffice formats, the self-hosted API Gotenberg is worth checking out

I found a project that does exactly that (https://github.com/gotenberg/gotenberg). It’s my best bet for now, but I still need to test GraalVM integration with JS runtimes (and test JS libraries) and the Kotlin compiler targeting Node.

Gotenberg is a Docker-based stateless API for PDF generation from HTML and Markdown files.

Think you mean https://gotenberg.dev ?

We use https://gotenberg.dev/ with handlebars templates.
