TSCodegen.WebAPI 1.2.3

TSCodegen.WebAPI

Library for C# ASP.NET controllers conversion to TypeScript axios services. Available as NuGet package.

Based on TSCodegen library.

Compatible with .NET Standard 2.0 and higher!

How it works

Codegen will examine calling assembly for all classes with the ApiController attribute. Then for each matching class Codegen will iterate over all methods with any attribute that starts with "Http" prefix (e.g. HttpGet).

Codegen will also handle methods with first argument having attribute FromBody for GET, DELETE, HEAD, OPTIONS methods and FromForm for POST, PUT, PATCH methods, though such methods must contain only one argument.

Prerequisites

Install axios and qs (querystring) to your frontend project.

npm i axios
npm i qs

Usage

Add to the start of the Main function:

#if DEBUG
Codegen.Run(new Codegen.Config
{
    OutputPath = @"\ui\api",
    AxiosImportPath = @"axios",
    Indentation = 4,
    IgnoreControllers = new()
    {
        typeof(BaseController),
    },
    ForbiddenNamespaces = new()
    {
        "Project.Database.Core.Entities",
    }
});
#endif

Codegen.Config properties

OutputPath

Output path that is relative to the .sln file.

AxiosImportPath

Path for import expression, e.g. with axios value will emit import axios from "axios";. Can be used to specify custom file with axios instance default export.

Indentation

Space indentation size for generated code.

IgnoreControllers

List of controllers that will be omited.

ForbiddenNamespaces

List of namespaces that entities of will throw exception.

DateTime conversion

C# DateTime class will be converted to Date | DateTimeString. You need to declare DateTimeString in any of your *.d.ts files. Example:

declare type DateString = "YYYY-MM-DD";
declare type TimeString = "HH:mm:ss";
declare type DateTimeString = `${DateString}T${TimeString}`;

Generated files

Library will generate file structure:

api\
├ myController\
│  ├ myMethod1.ts
│  ├ myMethod2.ts
│  ├ types.ts
│  └ index.ts
└ index.ts

Where api\index.ts will contain default export with all APIs as objects with functions (e.g. api.myController.myMethod).
