Modules - inside a Request Server

A Request Server supplies static data to the front end of your application.

When a user at the front end requests a snapshot of data from a table or a view, the relevant requestReply code in the Request Server retrieves the data and sends it to the front end. Once the response is received, the transaction is complete.

Each requestReply query is designed to supply all or some data from the specified table or view. You must specify all the required requestReply queries in a single Kotlin script file. If your application is called bravo, then this file will be called bravo-reqrep.kts.

Here is a simple example of a Request Server file. It defines three requestReply queries:

  • the first returns all the fields in the COUNTERPARTY table
  • the second returns all the fields in the EXCHANGE table
  • the third includes a request block, which specifies the two fields ALTERNATE_TYPE and INSTRUMENT_CODE as a primary key; it responds with four fields from the INSTRUMENT_DETAILS table
requestReplies {


request {

reply {

Your application will certainly have many more queries, but that covers the basics. Generally speaking, if you create your tables and views carefully, you can keep your reqrep.kts simple.
