A reverse web proxy that adds a POST /multirequest
endpoint to any web server. This endpoints accepts
JSON requests of the form:
[ COMMAND, ... ]
Where each COMMAND
is an object like the following:
{
"type": "get",
"path": "/posts",
"query": QUERY,
"slot": "posts"
}
Where the key query
is optional, and QUERY
is an
arbitrarily complex object to be converted into a query
string by the qs
library.
Additionally, any value inside QUERY
can be of the form:
{
"fromSlot": "posts",
"key": "authorId"
}
Or an array of those. E.g.:
[
{
"type": "get",
"path": "/posts",
"slot": "posts"
},
{
"type": "get",
"path": "/comments",
"query": {
"postId": { "fromSlot": "posts", "key": "id" }
},
"slot": "comments"
},
{
"type": "get",
"path": "/users",
"query": {
"id": [
{ "fromSlot": "posts", "key": "authorId" },
{ "fromSlot": "comments", "key": "authorId" }
]
},
"slot": "users"
},
]
Those will be expanded according to the data in the specified slots.
If none of the requests to the backend fail, the accumulated slots are returned as the multirequest's response.
