# How to configure Continuous Integration (CI) build caching
@doc-version: 16.0.4


To improve build performance, Next.js saves a cache to `.next/cache` that is shared between builds.

To take advantage of this cache in Continuous Integration (CI) environments, your CI workflow will need to be configured to correctly persist the cache between builds.

> If your CI is not configured to persist `.next/cache` between builds, you may see a [No Cache Detected](/docs/messages/no-cache.md) error.

Here are some example cache configurations for common CI providers:

## Vercel

Next.js caching is automatically configured for you. There's no action required on your part. If you are using Turborepo on Vercel, [learn more here](https://vercel.com/docs/monorepos/turborepo).

## CircleCI

Edit your `save_cache` step in `.circleci/config.yml` to include `.next/cache`:

```yaml
steps:
  - save_cache:
      key: dependency-cache-{{ checksum "yarn.lock" }}
      paths:
        - ./node_modules
        - ./.next/cache
```

If you do not have a `save_cache` key, please follow CircleCI's [documentation on setting up build caching](https://circleci.com/docs/2.0/caching/).

## Travis CI

Add or merge the following into your `.travis.yml`:

```yaml
cache:
  directories:
    - $HOME/.cache/yarn
    - node_modules
    - .next/cache
```

## GitLab CI

Add or merge the following into your `.gitlab-ci.yml`:

```yaml
cache:
  key: ${CI_COMMIT_REF_SLUG}
  paths:
    - node_modules/
    - .next/cache/
```

## Netlify CI

Use [Netlify Plugins](https://www.netlify.com/products/build/plugins/) with [`@netlify/plugin-nextjs`](https://www.npmjs.com/package/@netlify/plugin-nextjs).

## AWS CodeBuild

Add (or merge in) the following to your `buildspec.yml`:

```yaml
cache:
  paths:
    - 'node_modules/**/*' # Cache `node_modules` for faster `yarn` or `npm i`
    - '.next/cache/**/*' # Cache Next.js for faster application rebuilds
```

## GitHub Actions

Using GitHub's [actions/cache](https://github.com/actions/cache), add the following step in your workflow file:

```yaml
uses: actions/cache@v4
with:
  # See here for caching with `yarn`, `bun` or other package managers https://github.com/actions/cache/blob/main/examples.md or you can leverage caching with actions/setup-node https://github.com/actions/setup-node
  path: |
    ~/.npm
    ${{ github.workspace }}/.next/cache
  # Generate a new cache whenever packages or source files change.
  key: ${{ runner.os }}-nextjs-${{ hashFiles('**/package-lock.json') }}-${{ hashFiles('**/*.js', '**/*.jsx', '**/*.ts', '**/*.tsx') }}
  # If source files changed but packages didn't, rebuild from a prior cache.
  restore-keys: |
    ${{ runner.os }}-nextjs-${{ hashFiles('**/package-lock.json') }}-
```

## Bitbucket Pipelines

Add or merge the following into your `bitbucket-pipelines.yml` at the top level (same level as `pipelines`):

```yaml
definitions:
  caches:
    nextcache: .next/cache
```

Then reference it in the `caches` section of your pipeline's `step`:

```yaml
- step:
    name: your_step_name
    caches:
      - node
      - nextcache
```

## Heroku

Using Heroku's [custom cache](https://devcenter.heroku.com/articles/nodejs-support#custom-caching), add a `cacheDirectories` array in your top-level package.json:

```javascript
"cacheDirectories": [".next/cache"]
```

## Azure Pipelines

Using Azure Pipelines' [Cache task](https://docs.microsoft.com/en-us/azure/devops/pipelines/tasks/utility/cache), add the following task to your pipeline yaml file somewhere prior to the task that executes `next build`:

```yaml
- task: Cache@2
  displayName: 'Cache .next/cache'
  inputs:
    key: next | $(Agent.OS) | yarn.lock
    path: '$(System.DefaultWorkingDirectory)/.next/cache'
```

## Jenkins (Pipeline)

Using Jenkins' [Job Cacher](https://www.jenkins.io/doc/pipeline/steps/jobcacher/) plugin, add the following build step to your `Jenkinsfile` where you would normally run `next build` or `npm install`:

```yaml
stage("Restore npm packages") {
    steps {
        // Writes lock-file to cache based on the GIT_COMMIT hash
        writeFile file: "next-lock.cache", text: "$GIT_COMMIT"

        cache(caches: [
            arbitraryFileCache(
                path: "node_modules",
                includes: "**/*",
                cacheValidityDecidingFile: "package-lock.json"
            )
        ]) {
            sh "npm install"
        }
    }
}
stage("Build") {
    steps {
        // Writes lock-file to cache based on the GIT_COMMIT hash
        writeFile file: "next-lock.cache", text: "$GIT_COMMIT"

        cache(caches: [
            arbitraryFileCache(
                path: ".next/cache",
                includes: "**/*",
                cacheValidityDecidingFile: "next-lock.cache"
            )
        ]) {
            // aka `next build`
            sh "npm run build"
        }
    }
}
```
