Manage "require" in custom plugins microgateway

[bertrandbely]

Hi community,

On microgateway, I need to update extauth to accept RS512 algorithm.

I duplicated the extauth standard plugin to the edgemicro/plugins folder and renamed it extauth2.

I modified the contsant acceptAlg to accept RS512.

But when I start the microgateway, I get the following error :

rror: Cannot find module 'jsrsasign'

Any idea ?

Thanks

Bertrand

Did you try

Npm install

And install all dependencies

the plug-ins package.Json has that dependency https://github.com/apigee/microgateway-plugins/blob/master/extauth/package.json

Hi SatK,

No, it doesn't change, I still have the error.

Thanks for help

We are having the same issues with Cloud Foundry. We are trying to customize the extauth plugin to exclude validation of certain urls. The customized plugin(extauth2) is not able to import the jsrsasign module while deploying/pushing the Gateway to cloud foundry.

Any resolutions?
