## Overview

This is the MongoDB Adapter for [`next-auth`](https://next-auth.js.org). This package can only be used in conjunction with the primary `next-auth` package. It is not a standalone package.

## Getting Started

1. Install `mongodb`, `next-auth` and `@next-auth/mongodb-adapter`

```js
npm install mongodb next-auth @next-auth/mongodb-adapter@next
```

2. Add `lib/mongodb.js`

```js
// This approach is taken from https://github.com/vercel/next.js/tree/canary/examples/with-mongodb
import { MongoClient } from "mongodb"

const uri = process.env.MONGODB_URI
const options = {
  useUnifiedTopology: true,
  useNewUrlParser: true,
}

let client
let clientPromise

if (!process.env.MONGODB_URI) {
  throw new Error("Please add your Mongo URI to .env.local")
}

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).
  if (!global._mongoClientPromise) {
    client = new MongoClient(uri, options)
    global._mongoClientPromise = client.connect()
  }
  clientPromise = global._mongoClientPromise
} else {
  // In production mode, it's best to not use a global variable.
  client = new MongoClient(uri, options)
  clientPromise = client.connect()
}

// Export a module-scoped MongoClient promise. By doing this in a
// separate module, the client can be shared across functions.
export default clientPromise
```

3. Add this adapter to your `pages/api/[...nextauth].js` next-auth configuration object.

```js
import NextAuth from "next-auth"
import { MongoDBAdapter } from "@next-auth/mongodb-adapter"
import clientPromise from "lib/mongodb"

// For more information on each option (and a full list of options) go to
// https://next-auth.js.org/configuration/options
export default NextAuth({
  adapter: MongoDBAdapter(clientPromise),
  ...
})
```
