# Configuring the Build ID
|
|
|
|
Next.js uses a constant id generated at build time to identify which version of your application is being served. This can cause problems in multi-server deployments when `next build` is ran on every server. In order to keep a static build id between builds you can provide your own build id.
|
|
|
|
Open `next.config.js` and add the `generateBuildId` function:
|
|
|
|
```js
|
|
module.exports = {
|
|
generateBuildId: async () => {
|
|
// You can, for example, get the latest git commit hash here
|
|
return 'my-build-id'
|
|
},
|
|
}
|
|
```
