"RangeError: Maximum call stack size exceeded" (urlencode) / "SyntaxError: Unexpected token" (json)

See original GitHub issue

Hello. I have this code:

var express = require("express")
var bp = require("body-parser")
var app = express()
var bpurle= app.use(bp.urlencoded({ extended: false }))
var bpjson= app.use(bp.json())
app.post("/urle", bpurle, function(req, res) {
    if (req.body === undefined) {return(console.log("There aren't any data"))}
    console.log("Received data via URL-Encode:\n" + req.body)
})
app.post("/json", bpjson, function(req, res) {
    if (req.body === undefined) {return(console.log("There aren't any data"))}
    console.log("Received data via JSON:\n" + JSON.stringify(req.body,null,2))
})
app.listen(4000)

When I execute…

curl -X POST http://127.0.0.1:4000/urle -d "data1=value1&data2=1234"

…I get this error:

RangeError: Maximum call stack size exceeded

Ok, I see. you created a circular dependency. You just need to remove the two app.use() statements to make your server look like this:

var express = require("express")
var bp = require("body-parser")
var app = express()
var bpurle= bp.urlencoded({ extended: false })
var bpjson= bp.json()
app.post("/urle", bpurle, function(req, res) {
    if (req.body === undefined) {return(console.log("There aren't any data"))}
    console.log("Received data via URL-Encode:\n" + req.body)
})
app.post("/json", bpjson, function(req, res) {
    if (req.body === undefined) {return(console.log("There aren't any data"))}
    console.log("Received data via JSON:\n" + JSON.stringify(req.body,null,2))
})
app.listen(4000)

It’s no problem, I didn’t even notice it at first, which is why I wanted to confirm that was your server’s code before I ran it myself to figure it out 😃
