FluentGuard

Tiny guard library for fluent precondition assertion. Current it is implemented for use with c#. Maybe a support for TypeScript and Java may be added.

Also in the near future a .net core / .net standard release will be aviable.

Feel free to fork !

Description

Offers a fluent way for making preconditions in a guard style. The idea is to have preconditions always in the same syntax and have less code.

Examples

NotNull Check

Preconditions
            .For(DomainObjectId, nameof(DomainObjectId))
            .NotNull();

Using lambdas instead of hardcoded name

Preconditions
            .For(()=> DomainObjectId)
            .NotNull();

Multiple checks

Preconditions
            .For(DomainObjectId, nameof(DomainObjectId))
            .NotNull()
            .MinLength(3);

Validaten models annotated with System.ComponentModel.DataAnnotations

Preconditions
            .For(()=>Model)
            .NotNull()
            .ValidateModel();

Next Steps

• Add api-documentation
• Make better names
• Support .net standard
• Implement TypeScript
