# trpc-swift
Generates native Swift clients for tRPC apps.
# Installation
Available as a npm package.
```
npm install --save-dev trpc-swift
```
# Usage
```
Usage: trpc-swift -r [routerName] -i [routerPath] -o [outputPath]
Options:
-r, --router-name Set the router name that should be found in the input file
-i, --input Set the path where the tRPC input tRPC router is located
-o, --output Set the output path for the generated Swift client
-g, --global-mode Control which models are placed by default in the global scope.
all All named models will be placed in the global scope by default.
top Only named models directly referenced by routes will be placed in the global scope by default.
none No models will be placed in the global scope by default.
-p, --public Assign the public access modifier for all generated Swift models and routes.
-a, --alias Create public type aliases for all models in the global scope.
-s, --shared Create a shared singleton instance of the generated Swift client.
-h, --help Display this help message
-q, --quiet Run in quiet mode (no output except for fatal errors)
```
# Generation
All routes in the input router are automatically detected and converted into Swift classes. Nested routers create nested Swift classes, tRPC procedures get converted into Swift methods. All referenced Zod input/output schemas, as well as their children get converted into Swift structures.
For instance, the following tRPC router and Zod schemas:
```
extendZodWithSwift(z);
const userSchema = z
.object({
id: z.string().uuid(),
name: z.object({
first: z.string(),
middle: z.string().optional(),
last: z.string(),
}),
email: z.string().optional(),
dateCreated: z.date(),
})
.swift({
name: "User",
});
export const appRouter = router({
user: router({
get: authClientProcedure
.meta({
swift: {
description: "Fetches a user by ID.",
},
})
.input(
z.object({
id: userSchema.shape.id,
})
)
.output(userSchema)
.query(/** some implementation */),
}),
});
```
will result in the following generated Swift client:
```
class AppRouter: TRPCClientData {
lazy var user = UserRoute(clientData: self)
// Scaffolding omitted
init(baseUrl: URL? = nil, middlewares: [TRPCMiddleware] = []) {
self.baseUrl = baseUrl
self.baseMiddlewares = middlewares
}
struct User: Codable, Equatable {
var id: String
struct Name: Codable, Equatable {
var first: String
var middle: String?
var last: String
}
var name: Name
var email: String?
var dateCreated: Date
}
class UserRoute: TRPCClientData {
let clientData: TRPCClientData
// Scaffolding omitted...
struct GetInputType: Codable, Equatable {
var id: String
}
/// Fetches a user by ID.
func get(input: GetInputType) async throws -> User {
return try await TRPCClient.shared.sendQuery(url: url.appendingPathExtension("get"), middlewares: middlewares, input: input)
}
}
}
```
The generated Swift class is self-contained, handles networking and routing. All you need to do is add it to your Swift project.
