How to use chromium engine?

[Rafiot]

I have a hard time figuring out how to use the chromium engine.

If I understand the documentation right, I should be able to pass a parameter engine=chromium in a GET query:

http://127.0.0.1:8050/info?wait=0.5&images=1&expand=1&timeout=90.0&engine=chromium&url=http%3A%2F%2Fgoogle.com&lua_source=function+main(splash%2C+args)%0D%0A++assert(splash%3Ago(args.url))%0D%0A++assert(splash%3Await(0.5))%0D%0A++return+{%0D%0A++++html+%3D+splash%3Ahtml()%2C%0D%0A++++png+%3D+splash%3Apng()%2C%0D%0A++++har+%3D+splash%3Ahar()%2C%0D%0A++}%0D%0Aend

But it returns:

{
    "error": 400,
    "type": "BadOption",
    "description": "Incorrect HTTP API arguments",
    "info": "engine=chromium is not supported yet"
}

Splash is started this way: docker run -p 8050:8050 -p 5023:5023 scrapinghub/splash --disable-browser-caches --browser-engines=webkit,chromium

---

if I start splash with docker run -p 8050:8050 -p 5023:5023 scrapinghub/splash --disable-browser-caches --browser-engines=webkit

the error message is:

{
    "error": 400,
    "type": "BadOption",
    "description": "Incorrect HTTP API arguments",
    "info": {
        "type": "bad_argument",
        "argument": "engine",
        "description": "Disabled render engine chromium"
    }
}

Which makes sense.

And for completeness-sake, if I start splash with docker run -p 8050:8050 -p 5023:5023 scrapinghub/splash --disable-browser-caches --browser-engines=chromium

And pass engine=webkit

The error message also makes sense:

{
    "error": 400,
    "type": "BadOption",
    "description": "Incorrect HTTP API arguments",
    "info": {
        "type": "bad_argument",
        "argument": "engine",
        "description": "Disabled render engine webkit"
    }
}

Am I missing something? The chromium engine feature is in alpha mode, and I'm not planning to use it in prod any time soon, but I wanted to give it a try.

You are reading the documentation of the render.html endpoint of Splash, which is not the endpoint that you are using. Chromium is only supported to render HTML, PNG and JPEG.
