# Configuring onDemandEntries
|
|
|
|
Next.js exposes some options that give you some control over how the server will dispose or keep in memory built pages in development.
|
|
|
|
To change the defaults, open `next.config.js` and add the `onDemandEntries` config:
|
|
|
|
```js
|
|
module.exports = {
|
|
onDemandEntries: {
|
|
// period (in ms) where the server will keep pages in the buffer
|
|
maxInactiveAge: 25 * 1000,
|
|
// number of pages that should be kept simultaneously without being disposed
|
|
pagesBufferLength: 2,
|
|
},
|
|
}
|
|
```
