Request type

Request for enhancement of a component

Functionality

Description

The goal is to add the "strictNullChecks": true to the config file and get it to work fine with every part of the project.

"useDefineForClassFields": false,
"strictNullChecks": true

To do so, we can work on mutiple branches focusing on a specific directory and get the files in it to comply with the rule, one by one.

Using validate:ts we can check only the directory we're interested into :

Example

npm run validate:ts -- --strictNullChecks src/app/utils/*.ts

This is a suggestion to make the code base more safe. Currently, many issues can happen because of this.

This needs to fix many many things in the code (see CI or run npm run build) before this can be merged (CI ticks green), the config can be enabled only on some folders first to split the work in smaller pieces.

Issues

• error when opening macro editor osrd#13531
