Help with Blitz Auth

[signal bolt]

I am trying to implement Blitz Auth in a NextJS project. I am following the docs but i am stuck here: https://blitzjs.com/docs/blitz-auth-with-next#without-prisma where i need to use prisma storage or redis storage. In this case, i am using a third party rest api. Any help on how i'd add the session storage?

yeah, so you need to define all the getSession, deleteSession etc functions. Instead of redis, you'll do a fetch call to your API.

const { gSSP, gSP, api } = setupBlitz({
  plugins: [
    AuthServerPlugin({
      cookiePrefix: "blitz-app-prefix",
      isAuthorized: simpleRolesIsAuthorized,
      storage: {
        createSession: (session: SessionModel): Promise<SessionModel> => {
          return new Promise<SessionModel>((resolve, reject) => {
            getAuthRedis().set(
              `token:${session.handle}`,
              JSON.stringify(session),
              (err) => {
                if (err) {
                  reject(err)
                } else {
                  getAuthRedis().lpush(
                    `device:${String(session.userId)}`,
                    session.handle
                  )
                  resolve(session)
                }
              }
            )
          })
        },
        deleteSession(handle: string): Promise<SessionModel> {
          return new Promise<SessionModel>((resolve, reject) => {
            getAuthRedis()
              .get(`token:${handle}`)
              .then((result) => {
                if (result) {
                  const session = JSON.parse(result) as SessionModel
                  const userId = session.userId as unknown as string
                  getAuthRedis().lrem(userId, 0, handle).catch(reject)
                }
                getAuthRedis().del(handle, (err) => {
                  if (err) {
                    reject(err)
                  } else {
                    resolve({ handle })
                  }
                })
              })
          })
        },

here's the interface, but I just realized we don't have the SessionModel type in there
https://blitzjs.com/docs/auth-config#customize-session-persistence-and-database-access

export interface SessionModel extends Record<any, any> {
  handle: string
  userId?: PublicData["userId"] | null
  expiresAt?: Date | null
  hashedSessionToken?: string | null
  antiCSRFToken?: string | null
  publicData?: string | null
  privateData?: string | null
}
