#New CLI commands
In version 1, there were many commands to use, and this, in a specific order. Running and generating migrations from model changes required four commands and building the whole application needed three.
In version 2, the number of CLI commands has been reduced and they have been simplified so that one action matches one command.
This command generates migrations by comparing the current database schema and the latest changes in your models.
This command builds and runs all migrations.
#Build and run scripts in watch mode (development)
If you want to re-build your scripts each time a file is change, you can execute
npm run develop in a separate terminal.
#Revert one migration
This command reverts the last executed migration.
#Build migrations, scripts and the app
This command builds the application, the scripts and the migrations. Unit and e2e tests are not included.
#Service and Application Initialization
In version 1, it was possible to add an
init method to the
AppController class and
boot methods in the services to initialize the application. These features needed special options in order to be activated.
Starting from version 2, they are enabled by default.
This optional interface allows you to check that the
subControllers property has the correct type as well as the
#Custom Error-Handling & Hook Post Functions
In version 1, when an error was thrown or rejected in a hook or a controller method, the remaining hook post functions were not executed.
Starting from version 2, the error is directly converted to an
HttpResponseInternalServerError and passed to the next post hook functions.
This can be useful in case we want to use exceptions as HTTP responses without breaking the hook post functions.
#Accessing File Metadata during Uploads
When using the
@ValidateMultipartFormDataBody hook to handle file upload, it is now possible to access the file metadata.
||Encoding type of the file|
||Name of the file on the user’s computer|
