TypeLite Plus

Build Status:

TypeLite Plus is the utility that generates TypeScript definitions from .NET classes.

It's especially useful to keep your TypeScript classes on the client in sync with your POCO classes on the server.

This project is a fork of the original TypeLITE project, which is no longer being maintained.

.NET Standard 2.0 Support

TypeLite Plus has been recompiled for .NET Standard 2.0, so it can be used in all modern .NET app development.

Installation

TypeLite Plus has 4 NuGet packages. In most cases, you'll just add the TypeLitePlus metapackage to your project. That package references the following packages:

• TypeLitePlus.Core: the core library that contains all of the generator logic and attributes.
• TypeLitePlus.T4: contains the Example T4 template and the Manager.ttinclude file.

If you're building a .NET Core project, you're likely to run into issues where the Visual Studio reflection mechanism is loading .NET Framework versions of certain DLLs instead of .NET Core versions. .NET Core does not have a concept of Assembly Binding Redirects, so there is no solution to the problem under the current Visual Studio architecture. This renders the T4 system unusable for .NET Core projects.

There will be a fix coming in the .NET Core 3.0 timeframe. In the meantime, there's a different solution. DotNet-Script uses the Roslyn scripting APIs to execute CSX scripts on .NET Core. CSX files even let you pull in NuGet packages as references.

First, you'll need to open a console and type dotnet tool install -g dotnet-script. That will install DotNet-Script into the .NET Core toolchain. Then you can use the following NuGet package:

• TypeLitePlus.DotNetScript: contains the Example CSX script.

More instructions TBD.

Changelog

Version 2.1.0 (27 October 2020)

Added: Support for specifying the module output order using the .WithModuleSortOrder(namespace, int) option. Added: Support for outputting Enum values as strings using the .WithEnumMode(TsEnumModes.String) option.

Version 2.0.0 (7 October 2018)

Added: Rewritten for .NET Standard 2.0 support. Now works in any .NET project now. Added: DotNet-Script support for executing in .NET Core application (due to differences in reflection contexts between VS and .NET Core). Added: Support for outputting types as concrete Classes using the .WithMode(TsGenerationModes.Classes) option. Fixed: Manager.tt is now powered by a scaled-back version of the TemplateFileManager that ships with EF6. It's lighter and easier to maintain than the previous one.
