MongoDB 适配器
资源
设置
安装
npm install @auth/mongodb-adapter mongodb环境变量
MONGODB_URI=配置
./auth.ts
import NextAuth from "next-auth"
import { MongoDBAdapter } from "@auth/mongodb-adapter"
import client from "./lib/db"
export const { handlers, auth, signIn, signOut } = NextAuth({
adapter: MongoDBAdapter(client),
providers: [],
})MongoDB 适配器不会自动处理连接，因此您需要确保已将已连接的 MongoClient 传递给适配器。
添加 MongoDB 客户端
lib/db.ts
// This approach is taken from https://github.com/vercel/next.js/tree/canary/examples/with-mongodb
import { MongoClient, ServerApiVersion } from "mongodb"
if (!process.env.MONGODB_URI) {
throw new Error('Invalid/Missing environment variable: "MONGODB_URI"')
}
const uri = process.env.MONGODB_URI
const options = {
serverApi: {
version: ServerApiVersion.v1,
strict: true,
deprecationErrors: true,
},
}
let client: MongoClient
if (process.env.NODE_ENV === "development") {
// In development mode, use a global variable so that the value
// is preserved across module reloads caused by HMR (Hot Module Replacement).
let globalWithMongo = global as typeof globalThis & {
_mongoClient?: MongoClient
}
if (!globalWithMongo._mongoClient) {
globalWithMongo._mongoClient = new MongoClient(uri, options)
}
client = globalWithMongo._mongoClient
} else {
// In production mode, it's best to not use a global variable.
client = new MongoClient(uri, options)
}
// Export a module-scoped MongoClient. By doing this in a
// separate module, the client can be shared across functions.
export default client
