Share Data between Plugins in Kong JS PDK

[sinalkar]

Hi team,
Consider Scenario in which let's consider

1. Parent Plugin Holding All common Configurations and having Highest Priority
2. Child Plugin will get those common configurations from Parent and do action as per business logic

I tried with Custom nginx directive environment concept too which is https://docs.konghq.com/enterprise/2.5.x/property-reference/#injecting-nginx-directives , but it is not working for me.

docker run -it --name jskong \ --network=kong-net \ -e "KONG_DATABASE=postgres" \ -e "KONG_PG_HOST=kong-database" \ -e "KONG_PG_USER=kong" \ -e "KONG_PG_PASSWORD=kong" \ -e "KONG_CASSANDRA_CONTACT_POINTS=kong-database" \ -e "KONG_PROXY_ACCESS_LOG=/dev/stdout" \ -e "KONG_ADMIN_ACCESS_LOG=/dev/stdout" \ -e "KONG_PROXY_ERROR_LOG=/dev/stderr" \ -e "KONG_ADMIN_ERROR_LOG=/dev/stderr" \ -e "KONG_ADMIN_LISTEN=0.0.0.0:8001 reuseport backlog=16384, 0.0.0.0:8444 http2 ssl reuseport backlog=16384" \ -e "KONG_PLUGINSERVER_NAMES=js" \ -e "KONG_PLUGINSERVER_JS_SOCKET=/usr/local/kong/js_pluginserver.sock" \ -e "KONG_PLUGINSERVER_JS_START_CMD=/usr/local/bin/kong-js-pluginserver -v --plugins-directory /usr/local/kong/js-plugins" \ -e "KONG_PLUGINSERVER_JS_QUERY_CMD=/usr/local/bin/kong-js-pluginserver --plugins-directory /usr/local/kong/js-plugins --dump-all-plugins" \ -e "KONG_PLUGINS=bundled,global-config" \ -e "KONG_NGINX_MAIN_ENV=DATABASE_HOST; env DATABASE_PASSWORD; env DATABASE_USER; env DATABASE_NAME" \ -p 8000:8000 \ -p 8443:8443 \ -p 127.0.0.1:8001:8001 \ -p 127.0.0.1:8002:8002 \ -p 127.0.0.1:8444:8444 \ kong:1.0
but in my plugin with process.env it's not getting

It will be better if Parent => Child Plugin Data Shareable

Can you please guide how to do or access.

Hi @sinalkar you can use the kong.ctx.shared API

[sinalkar]

Thanks @fffonion .
I did
In parent plugin in access method : Priority 5000
await kong.ctx.shared.set('globalConfig',JSON.stringify(tmpConfig))

In Child Plugin i able to get in access method : Priority : 4000
await kong.ctx.shared.get('globalConfig')

and it's working
