wildcard redirects not working from 'firebase serve'

[rillomas]

I'm trying to redirect some requests from firebase serve to pub serve (Dart's local server) on a local machine, but the wildcard redirects seem to be not working.

I'm using the following firebase.json

{
  "database": {
    "rules": "database.rules.json"
  },
  "hosting": {
    "public": "web",
    "redirects": [{
      // Following works:
      // "source" : "/packages/web_components/webcomponents-lite.min.js",
      // "destination" : "http://localhost:8080/packages/web_components/webcomponents-lite.min.js",

      // Following doesn't work:
      "source" : "/packages/:file*",
      "destination" : "http://localhost:8080/packages/:file*"
    }]
  }
}

firebase-cli version: 3.7.0
superstatic version: 4.1.0
Windows 10 Pro x64

Still an issue on firebase-tools@3.9.2 😞

Just ran some unit tests and it fails on redirects with segments in urls, here's the output:

mocha test/unit/middleware/redirects.spec.js

  redirect middleware
    √ skips the middleware if there are no redirects configured (46ms)
    √ skips middleware when there are no matching redirects
    √ redirects to a configured path
    √ redirects to a configured path with a custom status code
    √ adds leading slash to all redirect paths
    √ redirects using glob negation
    1) redirects using segments in the url path
    2) redirects a missing optional segment
    3) redirects a present optional segment
    4) redirects a splat segment
    5) redirects using segments in the url path with a 302
    √ redirects to external http url
    √ redirects to external https url

    √ preserves query params when redirecting to external urls
    6) preserves query params when redirecting with captures

  11 passing (170ms)

Using Firebase Hosting and experiencing a related issue when attempting to use redirects with a combination of glob negation and segment capturing.

"redirects": [{
     "source" : "/one/!(a|b|c)/:end.html",
     "destination" : "/one/d/:end.html",
     "type" : 302
     }]

Does not redirect /one/z/test.html to /one/d/test.html as expected.

2 years passed, version 6.9.2 still have this error
lol, the code from official doc is not working localy

 "redirects": [ {
    "source": "/blog/:post*",  // captures the entire URL segment beginning at "post"
    "destination": "https://blog.myapp.com/:post", // includes the entire URL segment identified and captured by the "source" value
    "type": 301
  }, {
    "source": "/users/:id/profile",  // captures only the URL segment "id", but nothing following
    "destination": "/users/:id/newProfile",  // includes the URL segment identified and caputured by the "source" value
    "type": 301
  } ]

This seems to work with firebase-tools@7.11.0 (with superstatic@6.0.4) - possibly earlier versions too.

However, there seems to be a couple of limitations/deviations from the actual server (used for deployed apps):

1. The destination must include the trailing * for named segments. I.e. {source: '/foo/:rest*', destination: '/bar/:rest*'} works file, but {source: '/foo/:rest*', destination: '/bar/:rest'} (without the trailing * in destination) does not work with the emulator (while it does work on the deployed app).
   (Obviously, the work-around is to include the trailing * in the destination.)

2. If the source contains a named segment, the destination must include a named segment as well. I.e. {source: '/foo/:rest*', destination: '/bar/:rest*'} works as expected, but {source: '/foo/:rest*', destination: '/bar/baz'} does not work with the emulator (while it does work on the deployed app).
   (The work-around is to replace the named segment in the source with /** (since the named segment was not used in the destination anyway).)

It is not great that the behavior of the emulator/devserver deviates from that of the deployed app, but at least there are work-arounds available.

Does this work? wildcards+redirects?

[tfwyouloveher]

currently working (8.1.1) with relative redirects but not absolute ones 😒

[GuilhermeCouto]

Not working here with everything up-to-date. I tried all that you can imagine to do this below:

"redirects": [ {
"source": "/a/(any)",
"destination": "../a?u=(any)",
"type": 301
}]

Can somebody help me?

The official example itself is not working in emulator

  "redirects": [ {
    "source": "/blog/:post*",  // captures the entire URL segment beginning at "post"
    "destination": "https://blog.myapp.com/:post", // includes the entire URL segment identified and captured by the "source" value
    "type": 301
  }, {
    "source": "/users/:id/profile",  // captures only the URL segment "id", but nothing following
    "destination": "/users/:id/newProfile",  // includes the URL segment identified and captured by the "source" value
    "type": 301
  } ]

Having the same issue, as far as I know query parameters are not supported for "source" in redirects, just wondering if that's the current Firebase standpoint.

This post helped me this lately.

To me this if it has worked for me

{
    "hosting": {
        "cleanUrls": true,
        "trailingSlash": false,
        "public": "public",
        "ignore": [
            "firebase.json",
            "**/.*",
            "**/node_modules/**"
        ],
        "redirects": [
            {
                "source": "/index.html",
                "destination": "/index",
                "type": 301
            },
            {
                "source": "/networks.html",
                "destination": "/networks",
                "type": 301
            }
        ]
    }
}

A trivial configuration like

    "redirects": [ {
      "source": "/a",
      "destination": "/b",
      "type": 302
    } ]

does not work in the emulator, but works in deployed version. Is it a known limitation?
