yes.. it should get validated based on API key
like i should be able to map API's against API key. if user hits any other endpoint it should give error in response
example /hello /world /hi are 3 apis. /hello and /world is mapped to app1. if he tries to access /hi he should get unauthorized or invalid access error
As he is only authorized to use /hello and /world api only
I dont think such mechanism exists currently in express-gateway
@samuelkitazume:matrix.org Can you comment ?
Samuel Kitazume
If you cannot do that through the built in authorization... you can use a custom plugin for that
ok thanks ! any suggested Plugins ? @samuelkitazume:matrix.org
Samuel Kitazume
Hmm I meant you can code your custom plugin. In the project I was working on early this year I had to rely on AD groups, so I came up with a bunch of plugins...
Its very easy and straightforward
oh okay got it.. Thanks alot! @samuelkitazume:matrix.org

I'm trying to implement helmet (https://www.npmjs.com/package/helmet) as a custom policy within express-gateway, but I don't have access to the gatewayExpressApp to apply this globally at the gateway level, is there another way to implement this?

Hello. Can someone explain what I'm doing wrong please? I'm forwarding to a service, but it appears to be adding a trailing slash. If I hit localhost:9999/api/v1/apiary, it forwards to apiary:3000/crud/ (with the trailing slash) even though I've configured without the trailing slash (see gist for config - https://gist.github.com/MrSimonEmms/461ec255a73d55c09b4d6e945be0df5d)

If I remove the /crud on the service, it doesn't put a trailing slash on

Hello gentlemen, I'm having trouble finding good examples of tutorials on express-gateway, could someone recommend me?
New to EG but finding it confusing as there only seems to be JSON and YAML. Where is the JS code that I can hack?
Miguel Durán
Can the website that discusses the headers option under proxy be updated with an example? I input a rule to add a header, but then my gateway starts complaining that no service endpoint is present
I am new to Express gateway and from the Spring world- does express come with support for an endpoint equivalent to spring cloud gateways lb:/app or Zuul’s service endpoint?

Hi all, I'm exploring EQ as an option for a kubernetes project: is it possible to configure EG to perform TLS edge termination ? So the connection is protected up to the gateway and just http to the hidden service ? Sorry if the question sounds silly: I'm new to the tool.

@krishna-gennext_gitlab increase the limit of the middleware parser
Krishna M
is there any configuration?
Hi, is there any way to check endpoint exists or not ? Currently its giving cors error. (front tries to access Endpoint which is not registered in config).
shivam sharma
@krishna-gennext_gitlab go check express.json() in documentation of express, there you find a property name limit for express.json implement that
shivam sharma
@Linus6 there is a http request TRACE, go check that out.

I have this config

path: "/storems/store/order"
methods: ["POST", "OPTIONS"]


  - storeMs_send
  - cors:
      - action:
          origin: "*"
  - body-parser:
  - token-validation:
  - proxy:
      - action:
          serviceEndpoint: storems
          changeOrigin: true

url: ${STORE_MS_URL}

If front-end makes request to "/storems/store/orderAll"(unregistered endpoint in gateway).
Idealy it should return 404 but Gateway is returning CORS error(as cors is first policy in pipeline).
Intruducing a wildcard path would solve it(returns 404) but, is this the right way.

I have installed node multiple times on my system, but I am still not able to install any express gateway plugins.
Can anyone help with this, please?
I was able to resolve it by removing node_modules and package-lock.json inside the folder where gateway is installed and then using npm install
Earlier I was removing them from the place they were installed after installing node
