When I hosted a frontend client (React JS) and backend (NodeJS) server in hosting and functions combination, there were some scenarios where in I needed to send data (to server) which contained slash (so encoded them).

This was where the problem rose, the encoded component was automatically decoded by the firebase hosting itself and sent the wrong url to the underlying server.

Therefore firebase should give us the ability to turn on/off the decoding of encoded data url in firebase.json

my current firebase.json file -

{
"functions": [
{
"source": "functions",
"codebase": "default",
"ignore": [
"nodemodules",
".git",
"firebase-debug.log",
"firebase-debug..log"
]
}
],
"hosting": {
"public": "/functions/public",
"ignore": [
"firebase.json",
"/.",
"**/nodemodules/"
],
"rewrites": [
{
"source": "",
"function": "app"
}
]
}
}
