Bash Completion

To setup Bash completion, execute wasp completion and follow the instructions.

In project

• wasp start runs Wasp app in development mode. It opens a browser tab with your application running, and watches for any changes to .wasp or files in src/ to automatically reflect in the browser. It also shows messages from the web app, the server and the database on stdout/stderr.

• wasp clean deletes all generated code and other cached artifacts. If using SQlite, it also deletes the SQlite database. It is the Wasp equivalent to "try shutting it down and turning back on".

  $ wasp clean
  
  Deleting .wasp/ directory...
  Deleted .wasp/ directory.
  

• wasp build generates full web app code, ready for deployment. Use when deploying or ejecting. Generated code goes in the .wasp/build folder.

• wasp deploy makes it easy to get your app hosted on the web. Currently, Wasp offers support for Fly.io. Want another hosting provider? Let us know in Discord or make a PR by updating this TypeScript app!

• wasp telemetry prints telemetry status.

  $ wasp telemetry
  
  Telemetry is currently: ENABLED
  Telemetry cache directory: /home/user/.cache/wasp/telemetry/
  Last time telemetry data was sent for this project: 2021-05-27 09:21:16.79537226 UTC
  Our telemetry is anonymized and very limited in its scope: check https://wasp-lang.dev/docs/telemetry for more details.
  
  

• wasp deps prints the dependencies that Wasp uses in your project.

• wasp info prints basic information about current Wasp project.

Database

Wasp has a set of commands for working with the database. They all start with db and mostly call prisma commands in the background.

• wasp db migrate-dev ensures dev database corresponds to the current state of schema (entities): it generates a new migration if there are changes in the schema and it applies any pending migration to the database.

  • Supports a --name foo option for providing a migration name, as well as --create-only for creating an empty migration but not applying it.

• wasp db studio opens the GUI for inspecting your database.
