### MongoDB
|
||||||
|
|
||||||
|
To use mongodb storage you must install the 'mongodb' pachage in npm
|
||||||
|
|
||||||
|
`npm install mongodb`
|
||||||
|
|
||||||
|
Once you've done that, your config section should look like:
|
||||||
|
|
||||||
|
``` json
|
||||||
|
{
|
||||||
|
"type": "mongodb",
|
||||||
|
"connectionUrl": "mongodb://localhost:27017/database"
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
You can also just set the environment variable for `DATABASE_URL` to your database connection url.
|
||||||
|
|
||||||
|
Unlike with postgres you do NOT have to create the table in your mongo database prior to running.
|
||||||
|
|
||||||
|
You can also set an `expire` option to the number of seconds to expire keys in.
|
||||||
|
This is off by default, but will constantly kick back expirations on each view or post.
|
||||||
|
|
||||||
