Kraken.js为静态文件设置maxAge

Question

I'm trying to set the max-age for static files using Kraken.js (Express.js/Node.js)

I use to edit app.use(express.static(__dirname + '/public', { maxAge: oneDay }) to set this, but it looks like it is not available anymore.

Help would be greatly appreciated!

The maxAge option is still available in express' static middleware.

Assuming you're using kraken >= v1.0, serving static assets is handled for you by default. I cannot be certain without looking at your code but it's highly likely your app.use(express.static ... isn't actually doing anything since, again, kraken defaults to serving up your static assets for you. Try removing it and seeing if your static assets are still being served up.

If that's the case, you'll want to set the maxAge config inside your config/config.json (or config/development.json if you want to have a different value in development).

This is what that would look like in your config ( 864e5 being the number of ms in a day):

{
    "middleware": {
        "static": {
            "module": {
                "name": "serve-static",
                "arguments": [
                    "path:./public",
                    { "maxAge": 864e5 }
                ]
            }
        }
    }
}
