[paolog22]

[chouglesaud]

@paolog22 what do you mean by ''why is it not strict thanks"

[Meskat]

are you talking about the TypeScript setting??

[paolog22]

@Meskat yes. when i try making it strict it produces a lot of errors .. @chouglesaud

[chouglesaud]

The strict flag enables a wide range of type checking behavior that results in stronger guarantees of program correctness.

@chouglesaud i know. but why the code is not ? sorry i am just trying to understand what is behind it .

[chouglesaud]

but why the code is not

can you give an example so I can understand?

strict: true will enable all type checking rule like following

• strictNullChecks
• alwaysStrict
• ...

for example if you set strictNullChecks to false typescript will just ignore the type checking for variable whether it is null or undefined. on the other hand, if you set to true then it will throw errors.

there is a simple example given in doc's checkout

Hi there,

I had a typing problem on my project, here's and sample from the file AfterUserCreated :

    DomainEvents.register(this.onUserCreatedEvent.bind(this), UserCreatedEvent.name);
  }

Turn out that when enabling strict mode, the compiler complains with  Property 'user' is missing in type 'IDomainEvent' but required in type 'UserCreatedEvent'.
