Typescript support planned?

[novelette17]

Your question
I want to use next-auth with Typescript. As far as I can see there is no Typescript support right now. There is not even a type declaration file yet (*.d.ts files)

Feedback
Documentation refers to searching through online documentation, code comments and issue history. The example project refers to next-auth-example.

• Found the documentation helpful
• Found documentation but was incomplete
• Could not find relevant documentation
• Found the example project helpful
• Did not find the example project helpful

Totally agree, I got an issue when using strict mode in typescript mostly are database config.

// https://typeorm.io/#/connection-options/postgres--cockroachdb-connection-options
  database: {
    type: 'cockroachdb',
    host: String(process.env.DATABASE_HOST),
    port: 26257,
    username: String(process.env.DATABASE_USER),
    password: String(process.env.DATABASE_PASSWORD),
    database: String(process.env.DATABASE_NAME),
    ssl: {
      rejectUnauthorized: false,
      ca: fs.readFileSync('./certificates/db/root.crt').toString(),
      key: fs.readFileSync('./certificates/db/client.puchida.key').toString(),
      cert: fs.readFileSync('./certificates/db/client.puchida.crt').toString(),
    },
  },
....

And the lint throw out this error. I've check there're incomplete field in some types.
:( then I workaround using @ts-ignore 😅
