3. Exposing Auth APIs

We will add all the backend APIs for auth on /auth/*. This can be changed by setting the apiBasePath property in the appInfo object on the backend and frontend. For the rest of this page, we will assume you are using /auth/*.

An example of this can be found here.

auth.js

import supertokens from "supertokens-node";
import { middleware } from "supertokens-node/framework/awsLambda";
import { getBackendConfig } from "./config";
import middy from "@middy/core";
import cors from "@middy/http-cors";

supertokens.init(getBackendConfig());

module.exports.handler = middy(middleware()).use(cors({
    origin: getBackendConfig().appInfo.websiteDomain,
    credentials: true,
    headers: ["Content-Type", ...supertokens.getAllCORSHeaders()].join(", "),
    methods: "OPTIONS,POST,GET,PUT,DELETE"
})).onError(request => {
    throw request.error;
});

    app_info=config.app_info, 
    framework=config.framework, 
    recipe_list=config.recipe_list, 
    mode="asgi",
)

app = FastAPI(title="SuperTokens Example")
app.add_middleware(get_middleware())

app = CORSMiddleware(
    app=app,
    allow_origins=[
        config.app_info.website_domain  
    ],
    allow_credentials=True,
    allow_methods=["GET", "PUT", "POST", "DELETE", "OPTIONS", "PATCH"],
    allow_headers=["Content-Type"] + get_all_cors_headers(),
)

handler = Mangum(app)

important

Notice that we called supertokens.init above. We will need to call this in all API endpoints that use any functions related to supertokens.
