Let's Run Something

Let’s execute our first application!

    cd $GOPATH/src/jiffy_tests/first_app
    go run main.go -dev -rs

Executing with the -dev and -rs flags instructs our new application to initialize itself using the development configuration file, and forces a rebuild of the ‘Super’ authorization-group. Consequently, some warning and info messages will scroll up the screen which is expected.

If all goes well, a message indicating that the application is running will be displayed. During the startup, the application executed a number of steps:

  1. Loaded the development configuration file.
  2. Initialized a handle to the underlying sqac ORM.
  3. Checked for and loaded the public and private keys for JWT support.
  4. Checked for and created the user, auth, and usrgroup tables in the database.
  5. Checked for and created the person table in the database based on the ‘Person’ model.
  6. Checked for and created authorizations in the database for each service end-point.
  7. Checked for and created the Super user-group in the database.
  8. Assigned all authorizations to the Super user-group.
  9. Created the ‘admin’ user and assigned it to the ‘Super’ user-group.
  10. Initialized the authorization, user, user-group and auth-groups caches in the router.
  11. Started the router.
  12. Looked at the leader-persistence store to determine the group-leader (running in standalone mode).
  13. Became the defacto group-leader, set own process-id (usually to 1 in this case).
  14. Updated the leader-persistence store with the new group-leader information.
  15. Started the inter-process failure-detector.

Congratulations! Your first application is now open for business at http://127.0.0.1:8080

Note that subsequent starts of the application should be done without the use of the -rs flag.

    cd $GOPATH/src/jiffy_tests/first_app
