Run new agent in parallel

This is the official documentation of the @forestadmin/agent Node.js agent.

This project will be used to test your new agent before replacing the old one.

The only consideration that you need to take into account for this step is that you want to be able to run both agents side by side.

For standalone agents

To help you create the new app, you can install the Forest CLI and use the command below

# for SQL project
forest projects:bundle:sql "aFolderName"
# or for No SQL project
forest projects:bundle:nosql "aFolderName"

This command will create all files and folders necesary to start your migration.

Both agents will be on different source trees and Node.js processes, so you can run them side by side as long as you don't use the same port.

For in-app agents

Because both agents probably call business code from your app, you will need to have both of them living in the same source tree and Node.js process during the migration.

To ensure that the two agents don't conflict with each other, you will need to change the following options:

createAgent({
  // ... [other options]

  // Change mounting point
  prefix: '/new-agent',

  // Change schema path to ensure both agents don't overwrite each other schemas
  schemaPath: 'new-agent/.forestadmin-schema.json',

  // Change the authSecret and envSecret so that the two agents show as two different
  // projects in the Forest Admin UI
  authSecret: process.env.TEMPORARY_FOREST_AUTH_SECRET,
  envSecret: process.env.TEMPORARY_FOREST_ENV_SECRET,
});

Enter the same prefix in the UI
