api getOauthClientMetadata {
  fn: import { getOauthClientMetadata } from "@src/server/getOauthClientMetadata.ts",
  httpRoute: (GET, "/oauth/client-metadata.json")
}

api getOauthClientMetadata {
  fn: import { getOauthClientMetadata } from "@src/server/getOauthClientMetadata.ts",
  httpRoute: (GET, "/oauth/client-metadata.json")
}

import { Request, Response } from 'express';

export const getOauthClientMetadata  = async (_req: Request, res: Response) => {
  res.setHeader('Content-Type', 'application/json');
  res.status(200).json({
    application_type: "web",
    client_id: "https://oauth-flask.demo.bsky.dev/oauth/client-metadata.json",
    client_name: "atproto OAuth Flask Backend Demo",
    client_uri: "https://oauth-flask.demo.bsky.dev/",
    dpop_bound_access_tokens: true,
