Debugging

Debugging dependency injection can be difficult. Timing and execution order is particularly important in understanding how an app using ts-injection is working and in effectively troubleshooting issues.

Enable detailed logging using the TSI_DEBUG environment variable.

ts-node TSI_DEBUG=* myapp.ts
process.env.TSI_DEBUG = "*";

Namespaces​

Debug logging can also be noisy. Logging in ts-injection uses namespaces to allow fine-grained control over which log you need to see.

  • autowire
  • injection_container
  • class_registry
  • injectable_repo
  • injectable
  • env

Levels​

Supported log levels:

  • debug
  • info
  • warn
  • error
  • * (all)
ts-node TSI_DEBUG=autowire=*,injection_container=info
process.env.TSI_DEBUG = "autowire=*,injection_container=info";
