[![pipeline status](https://gitlab.com/wondermonger/koa-session-mongoose/badges/v2.0.5/pipeline.svg)](https://gitlab.com/wondermonger/koa-session-mongoose/pipelines/15892902) [![coverage report](https://gitlab.com/wondermonger/koa-session-mongoose/badges/v2.0.5/coverage.svg)](https://wondermonger.gitlab.io/-/koa-session-mongoose/-/jobs/47039482/artifacts/coverage/index.html)

Mongoose storage layer for [koa-session](https://github.com/koajs/session).

## Installation

```shell
yarn add koa-session-mongoose
```

**OR**

```shell
npm i --save koa-session-mongoose
```

## Usage

### Prerequisites

This store requires [node@>=8.3.0](https://nodejs.org), [koa@>=2.0.0](http://koajs.com) and [koa-session@>=5.0.0](https://github.com/koajs/session).

If you are using older dependencies, consider using [koa-session-mongoose@\^1.0.0](https://gitlab.com/wondermonger/koa-session-mongoose/tree/v1.0.0).

### Code Examples

```javascript
const Koa = require('koa');
const mongoose = require('mongoose');
const MongooseStore = require('koa-session-mongoose');
const session = require('koa-session');

// mongoose connection must exist before creating a store with koa-session-mongoose
mongoose.connect('mongodb://some_host/some_db');

const app = new Koa();

// needed for cookie-signing
app.keys = ['some secret key'];

app.use(session({ store: new MongooseStore() }, app));

app.use(async ctx => {
  const { session } = ctx;
  let n = session.views || 0;
  session.views = ++n;
  ctx.body = `${n} view(s)`;
});

app.listen(3000);

```

You can optionally specify collection name (`collection`), model name (`name`), expiration time in seconds (`expires`), and Mongoose connection (`connection`):

```javascript
async function init (uri) => {
  const connection = await mongoose.connect(uri, { useMongoClient: true });

  app.use(session({
    store: new MongooseStore({
      collection: 'appSessions',
      connection: connection,
      expires: 86400, // 1 day is the default
      name: 'AppSession'
    })
  }, app));
}

```

A mirror of the project will persist at [https://github.com/mjbondra/koa-session-mongoose](https://github.com/mjbondra/koa-session-mongoose), but all future development will be directed to the new repository.

### Installation

```shell
yarn
```

### Linting

```shell
yarn lint
```

### Testing

```shell
# all tests
yarn test

# integration tests
yarn test:integration

# unit tests
yarn test:unit
```

If you require a MongoDB URI other than the default (`mongodb://127.0.0.1/koa-session-mongoose`), specify it as follows before executing `yarn test` or `yarn test:integration`:

```shell
MONGODB_URI="mongodb://[username:password@]host[:port]/[database]"
```
