Credit Card Interceptor

A JavaScript Interceptor that hides credit card numbers

You need to run RESTHeart with the GraalVM to execute this interceptor.

Check the java version to be GraalVM CE 21.1.0

$ java  -version
openjdk version "16.0.1" 2021-04-20
OpenJDK Runtime Environment GraalVM CE 21.1.0 (build 16.0.1+9-jvmci-21.1-b05)
OpenJDK 64-Bit Server VM GraalVM CE 21.1.0 (build 16.0.1+9-jvmci-21.1-b05, mixed mode, sharing)

Deploy

$ cp -r credit-card-hider ../restheart/plugins && touch ../restheart/plugins/credit-card-hider

Note that package.json defines cc-hider.js as an interceptor

"rh:interceptors": [
    "cc-hider.js"
  ]

For a service use the following declaration:

"rh:services": [
    "my-service.js"
  ],

In the RESTHeart logs you'll see something like:

 11:24:31.009 [Thread-1] INFO  o.r.polyglot.PolyglotDeployer - Added interceptor ccHider, description: hides credit card numbers
