How to Transition to Verified Routes in Phoenix 1.7

Source: fly.io

The article by Mark Ericksen describes the process of migrating legacy routing in a Phoenix application to the new Verified Routes feature introduced in Phoenix 1.7. Verified Routes offer readability, elegant syntax without a route helper with many arguments, and compile-time checks. The author suggests upgrading to Phoenix 1.7 before starting with the migration and stresses the necessity of handling static routes before using the automated mix task designed by Andreas Eriksson. This task simplifies the process by identifying and suggesting changes for most routes, but it does not handle multiline routes, certain query parameters, routes in comments, or invalid routes. The author shares personal experiences with the tool and provides tips on handling remaining issues after the initial pass. They also note adjustments necessary for Phoenix components using routes and eventually the successful completion of the migration, with no 'Routes.' calls remaining in the project, confirming the benefits of Verified Routes. Appreciation is shown for the community tool created by Andreas Eriksson.

Deploying Elixir Apps with structure.sql in Production Environments

Mark Ericksen discusses the problem of loading a structure.sql file in a production environment where mix is not available after building a mix release. He provides a solution that involves committing the structure.sql file to version control, adding the postgresql-client package to the Dockerfile, and updating the migrate/0 function in the release.ex file to run the structure.sql file when needed.
