Drills

A simple Elm app I built to help my kids do homework drills for school.

Troubleshooting

Creating Evergreen Migrations

Sometimes your PR's CI will fail with UNIMPLEMENTED MIGRATION error in the Lamdera Check step. This means that you need to create a new migration for the changes you've made:

$ git branch -D master
$ git checkout -b master
$ lamdera check
