Moesif Plugin for Express Gateway

Express Gateway is an open-source API Gateway/API Management application built on the Node.js express framework.

Moesif is the most advanced API analytics, monitoring and debugging platform. Moesif is used by thousands of developers to process billions of APIs calls.

This package is a plugin for Express Gateway to easily add Moesif's API analytics to your APIs served by Express Gateway.

How to install

  • Follow instructions for setting up Express Gateway

  • Install express-gateway-plugin-moesif: Within the folder of the Gateway created by Express Gateway, type in:

    npm install --save express-gateway-plugin-moesif
  • Add the moesif plugin to system.config.yml

    plugins:
      # express-gateway-plugin-example:
      #   param1: 'param from system.config'
      moesif:
        applicationId: your_moesif_application_id

    your_moesif_application_id is obtained from your Moesif account and is required.

    Other configuration options includes,

    • debug: turn on debug messages
    • sessionTokenHeader: Set the HTTP header key that contains your API's Authorization token/API key. Moesif tries to detect sessions automatically. However, if we cannot detect it correctly, you can specify which header field to use.
  • Add moesif policy to whitelist of your gateway.config.yml

    policies:
      - proxy
      # other policies.
      - moesif
  • Add moesif policy to your pipelines also in the gateway.config.yml.

    pipelines:
    - name: getting-started
      apiEndpoints:
        - api
      policies:
        - moesif:
        - key-auth:
        - proxy:
            - action:
                serviceEndpoint: httpbin
                changeOrigin: true
    

To capture all data for a pipeline, please make sure to put Moesif at the top of the pipeline. If You have multiple pipelines, be sure to add the moesif policy to each pipeline you want to capture data for.

Additional Info:

This plugin is a simple wrapper around the moesif-express middleware.

Since Express Gateway's configuration is designed to be declarative, some of the options from moesif-express that require a function are not ported over. We'll do so in the future.

In the mean time, if you need to use additional options, the easiest way is to fork this repo and add your required options to the middlewareCreator.js file.

You can’t perform that action at this time.
