Kkdev92.Tisilia.Generator 0.4.1-alpha

Tisilia

.NET and TypeScript, connected down to what the types mean. Tisilia reads an ASP.NET Core API from the running application — the endpoints it maps and the System.Text.Json options in effect for each — writes that down as a contract, and generates a TypeScript client that reads and writes exactly the JSON the server does: 64-bit integers, decimals, GUIDs, dates and durations keep their exact values, and what the contract cannot describe is reported with a diagnostic instead of being guessed.

Pre-release. Every version so far is one: dotnet add package and dotnet tool install need --prerelease.

Install

dotnet add package Kkdev92.Tisilia.AspNetCore --prerelease
dotnet tool install --local Kkdev92.Tisilia.Tool --prerelease     # after `dotnet new tool-manifest`

This readme ships in every Tisilia package.

The generated client runs on the npm package @kkdev92/tisilia-runtime, installed at the version of the CLI that generated it (dotnet tisilia version prints it).

Getting started

builder.Services.AddTisilia(o => o.ApiId = "shop");
var app = builder.Build();

app.MapGet("/orders/{id:guid}", (Guid id) => new Order(id, 9007199254740993L, 1234.50m))
   .WithTisiliaOperation("orders.get");          // only registered endpoints become operations

app.Run();

public sealed record Order(Guid Id, long Revision, decimal Total);

dotnet tisilia export --project src/Api --allow-execute-project     # starts the app once, writes src/Api/tisilia.contract.json
dotnet tisilia init --contract src/Api/tisilia.contract.json --output src/web/src/api
dotnet tisilia generate --config tisilia.json

The generated createShopClient(...).ordersGet({ id }) returns either the declared response — revision as an exact Int64, total as a Decimal that keeps 1234.50 — or a named failure such as unexpected-response, codec-failure, transport-failure or timeout; it does not throw for an HTTP or decoding problem.

Kkdev92.Tisilia.AspNetCore changes no JSON, CORS or authentication setting. It turns on the XML documentation file of the project that references it, without warnings for missing comments, so that /// comments reach the contract, the Explorer and the client's JSDoc; a project that sets GenerateDocumentationFile itself keeps its own setting. It also brings a source generator into that project's build, which reads the handlers of registered operations that declare no response types (Results.Ok(value), an IActionResult action) so that export can describe their responses, and adds one internal class with what it read.

Running code

export and conformance start your application and explorer build runs a package build, so each refuses to without --allow-execute-project, --allow-execute-adapters or --allow-execute-build. generate, check, validate, diff, init and watch never execute anything, and no command fetches code from a contract or a remote origin. The source generator reads source in the compiler and executes nothing of the application.
