How to send all non-declared paths to a specific target (catchall principle)

[dorian-y]

Hi,

I try to use the proxy to send the trafic in 4 directions :
1- Send some trafic to domain 1 for several paths
2- Send some trafic to domain 2 for several paths
3- Send all trafic to domain 3, except for some explicitly excluded paths : homepage / + /blog/**
4- Implicit (Not declarative) routing, to send the rest ( homepage / + /blog/** ) to be managed by the Nuxt Application itself

But when i configure the proxy like this,
I see that, any Path which is not declared explicitly is sent to the Nuxt app (with a 404)
But I would like those paths to be managed by my "domain 3".

Example : when I go to : "/path-3-random" (not declared in the proxy)
I would expect domain-3.com to be used, but this is my nuxt app who is used.
And because I have no internal route for this in Nuxt : I have a 404.

Note : I want to avoid to declare explictly all the paths that my domain-3.com can manage.

Any ideas ?
Hope to be clear enough.
Thanks for any input guys.

proxy: {
    options: [
      // Catch Some / Path 1
      {
        target: "https://domain-1.com",
        changeOrigin: true,
        pathFilter: [
          "/path-1a/**",
          "/path-1b/**",
        ],
      },
     // Catch Some / Path 2
      {
        target: "https://domain-2.com",
        changeOrigin: true,
        pathFilter: [
          "/path-2a/**",
          "/path-2b/**",
        ],
      },      
      // Catch all Except Exclusions
      {
        target: "https://domain-3.com",
        changeOrigin: true,
        pathFilter: [
          '!/blog/**',
          '!/**'
        ],
      },
    ],
  },

The configuration you are using is for the future 3.0 version. (pathFilter is new)

Not sure exactly how different frameworks implement HPM...

You could try to rename pathFilter to context.
Example documentation from webpack-dev-server: https://webpack.js.org/configuration/dev-server/#devserverproxy

Best is to have a look at the 2.x documentation
