Hello Node-RED community,
I've been trying to access the raw request body in a Node-RED project, specifically for processing Stripe webhook events, which require access to the raw body to verify their signature. I've tried several approaches, but none have been successful so far. I am seeking your guidance and expertise to help me solve this issue.
Here is what I've tried so far:
- Using the
httpNodeMiddlewarein thesettings.jsfile to intercept the request and parse the raw body using theraw-bodypackage:
const getRawBody = require('raw-body');
module.exports = {
// ...
httpNodeMiddleware: function (req, res, next) {
if (req.originalUrl === '/stripe/webhook' && req.method === 'POST') {
req.skipRawBodyParser = true;
getRawBody(req, {
length: req.headers['content-length'],
limit: '1mb',
encoding: 'utf8'
}, function (err, string) {
if (err) {
return next(err);
}
req.body = string;
next();
});
} else {
next();
}
},
// ...
};
This approach resulted in the following error: InternalServerError: stream is not readable.
- Trying different stream handling approaches like
on-finishedandbusboypackages, but they either produced the same error or were not suitable for handling raw JSON payloads.
const getRawBody = require('raw-body');
const onFinished = require('on-finished');
module.exports = {
// ...
httpNodeMiddleware: function (req, res, next) {
if (req.originalUrl === '/stripe/webhook' && req.method === 'POST') {
req.skipRawBodyParser = true;
console.log('httpNodeMiddleware', req.originalUrl);
// Ensure the request is fully processed before parsing the raw body
onFinished(req, function (err) {
if (err) {
return next(err);
}
// Parse the raw body
getRawBody(req, {
length: req.headers['content-length'],
limit: '1mb',
encoding: 'utf8'
}, function (err, string) {
if (err) {
return next(err);
}
req.body = string;
next();
});
});
} else {
next();
}
},
// ...
};
I am looking for a solution to access the raw request body in Node-RED without relying on additional dependencies or packages. Any suggestions, guidance, or examples would be greatly appreciated. Thank you in advance for your help!

But one thing you can do with it is tell it to use a custom ExpressJS instance. Now to be honest, I'm still not sure whether that instance will also apply the body interpretation but I don't think it does.
