How would I do that? I'm assuming you're using expressgiven the logs you have in your question. The key is to set the timeout property on server the following sets the timeout to one second, use whatever value you want :.

If you're not using express and are only working with vanilla node, the principle is the same. The following will not return data:. Refer to request 's documentation for other options. For specific request one can set timeOut to 0 which is no timeout till we get reply from DB or other server.

Like every second? Every ms? Where is this documented? Chin Lee Lee 2, 1 1 gold badge 17 17 silver badges 38 38 bronze badges. I have tried this,but it doesn't work.

Could it be server side time-out setting? We should really differentiate between incoming http request and outgoing http request. If you are using your node app as a proxy, you may want to use both require 'request' and require 'express'.

In such a case, when you make a data via the request module, it will only execute your callback once the request is complete. By specifying the timeout as Lee is suggesting, you are 'failing' the request and calling the callback before data is returned.

For me, this is often better than failing via express, as SomeKittens suggests, because I often require cleanup from my request before exiting the process. For specific request one can set timeOut to 0 which is no timeout till we get reply from DB or other server request.

This page is showing documentation for version v1. If you're looking for v0. All http-proxy options can be used, along with some extra http-proxy-middleware options. Providing an alternative way to decide which requests should be proxied; In case you are not able to use the server's path parameter to mount the proxy or when you need more flexibility. RFC path is used for context matching. For fine-grained control you can use wildcard matching. Glob pattern matching is done by micromatch.

Visit micromatch or glob for more globbing examples. Note : In multiple path matching, you cannot use string paths and wildcard paths together. For full control you can provide a custom function to determine which requests should be proxied or not. Object-keys will be used as RegExp to match paths. Default: 'info'.

Default: console. Subscribe to http-proxy events :. The following options are provided by the underlying http-proxy library.

Default: false. Default: null. Possible values:. Maybe you have some middleware that consumes the request stream before proxying it on e. If you read the body of a request into a field called 'req. Use the shorthand syntax when verbose configuration is not needed.

You don't provide enough information for me to know what "request timeout" means. If you are referring to Node. You see this is exactly the problem, i don't know how many timeouts are there. I am not talking about the browser timeout here, thats for sure. I am talking about the timeout that kills the request from nodejs end. How to get express to not timeout on a request. I don't care what node. BTW, request. I see tons of middlewares and none really documents this well. Some say there are issues with the same socket being multiplexed, etc.

One simple good answer is what is required in this regard. No, because express is just sugar on top of core, it's not an encapsulation of core. Everything that is Node. So if Node.For an introduction to routing, see Basic routing.

You define routing using methods of the Express app object that correspond to HTTP methods; for example, app. For a full list, see app.

You can also use app. In fact, the routing methods can have more than one callback function as arguments. With multiple callback functions, it is important to provide next as an argument to the callback function and then call next within the body of the function to hand off control to the next callback.

A route method is derived from one of the HTTP methods, and is attached to an instance of the express class. Express supports methods that correspond to all HTTP request methods: getpostand so on. There is a special routing method, app. Route paths, in combination with a request method, define the endpoints at which requests can be made.

Route paths can be strings, string patterns, or regular expressions. The characters? The hyphen - and the dot. Express uses path-to-regexp for matching the route paths; see the path-to-regexp documentation for all the possibilities in defining route paths.

Express Route Tester is a handy tool for testing basic Express routes, although it does not support pattern matching.

This route path will match abcdabbcdabbbcdand so on. This route path will match butterfly and dragonflybut not butterflymandragonflymanand so on. The captured values are populated in the req. To define routes with route parameters, simply specify the route parameters in the path of the route as shown below. Since the hyphen - and the dot. To have more control over the exact string that can be matched by a route parameter, you can append a regular expression in parentheses :.

In Express 4. This will likely be fixed in Express 5. You can provide multiple callback functions that behave like middleware to handle a request.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

I was wondering if anyone could tell me what the default HTTP request timeout is when using express. How do I alter this timeout for a single route? I would like to set it to about 15 minutes for a special audio conversion route. Try connect-timeout or use this:. The default request timeout in Node v0. That is what express uses. Learn more.

Dark Mode Beta - help us root out low-contrast and un-converted bits.If you define a response modifier userResDecorator, userResHeaderDecoratoror need to inspect the response before continuing maybeSkipToNextstreaming is disabled, and the request and response are buffered.

This can cause performance issues with large payloads. Many function hooks support Promises. If any Promise is rejected, next x is called in the hosting application, where x is whatever you pass to Promise.

The first positional argument is for the proxy host; in many cases you will use a static string here, eg. However, this argument can also be a function, and that function can be memoized or computed on each request, based on the setting of memoizeHost. Note: In express-http-proxythe path is considered the portion of the url after the host, and including all query params. Authors using this resolver must also handle the query parameter portion of the path.

Provide a proxyReqPathResolver function if you'd like to operate on the path before issuing the proxy request. Use a Promise for async operations. The filter option can be used to limit what requests are proxied. Return true to continue to execute proxy; return false-y to skip proxy for this request. Note that in the previous example, resolve false will execute the happy path for filter here skipping the rest of the proxy, and calling next.

When your proxied service returnsnot modified, this step will be skipped, since there is no body to decorate. Note: The other arguments proxyRes, userReq, userRes are passed by reference, so you can currently exploit this to modify either response's headers, for instance, but this is not a reliable interface.

I expect to close this exploit in a future release, while providing an additional hook for mutating the userRes before sending. If your proxy response is gzipped, this program will automatically unzip it before passing to your function, then zip it back up before piping it to the user response.

There is currently no way to short-circuit this behavior. This sets the body size limit default: 1mb. If the body size is larger than the specified or default limit, a Request Entity Too Large error will be returned. See bytes. When true, the host argument will be parsed on first request, and memoized for subsequent requests.

In this example, when memoizeHost:falsethe coinToss occurs on each request, and each request could get either value. Conversely, When memoizeHost:truethe coinToss would occur on the first request, and all additional requests would return the value resolved on the first request.

Allows you to inspect the proxy response, and decide if you want to continue processing via express-http-proxy or call next to return control to express. If you would like to modify this behavior, you can provide your own proxyErrorHandler. You can override most request options before issuing the proxyRequest.

NOTE: req. Normally, your proxy request will be made on the same protocol as the host parameter. If you'd like to force the proxy request to be https, use this option. The parseReqBody option allows you to control parsing the request body. For example, disabling body parsing is useful for large uploads where it would be inefficient to hold the data in memory. When false, no action will be taken on the body and accordingly req.

Note that setting this to false overrides reqAsBuffer and reqBodyEncoding below. The reqAsBuffer option allows you to ensure the req body is encoded as a Node Buffer when sending a proxied request.

Any value for this is truthy.To enable the Proxy policy, add proxy in gateway. You probably noticed there are 3 options that concern the path : prependPathignorePath and stripPath. There might be cases where a set of Proxy options is valid for an entire service endpoint.

If you have, for example, a service endpoint on an host and then multiple pipelines based on a path — you might end up setting the same options per each pipeline. In that case, you can either use yaml referencesor set the proxyOptions parameter on the serviceEndpoint directly.

The proxyOptions object will be forwarded to the node-http-proxy middleware. Some corporation allow access to internet only through proxy. In this case you need to specifically tell Express-Gateway to use proxy to forward requests. This type of policy should generally be placed last in the policies list within a pipeline. Usage To enable the Proxy policy, add proxy in gateway. See more details below. Default: false. Default: null. Possible values: false default : disable cookie rewriting String: new domain, for example cookieDomainRewrite: "new.
