# Environment Variables The following environment variables are ones that you can set to change the behavior of Nx in different environments. | Property | Type | Description | | --------------------------------- | ------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | | NX_ADD_PLUGINS | boolean | If set to `false`, Nx will not add plugins to infer tasks. This is `true` by default. Workspaces created before Nx 18 will have this disabled via a migration for backwards compatibility | | NX_BASE | string | The default base branch to use when calculating the affected projects. Can be overridden on the command line with `--base`. | | NX_CACHE_DIRECTORY | string | The cache for task outputs is stored in `.nx/cache` by default. Set this variable to use a different directory. | | NX_CACHE_PROJECT_GRAPH | boolean | If set to `false`, disables the project graph cache. Most useful when developing a plugin that modifies the project graph. | | NX_DAEMON | boolean | If set to `false`, disables the Nx daemon process. Disable the daemon to print `console.log` statements in plugin code you are developing. | | NX_DEFAULT_PROJECT | string | The default project used for commands which require a project. e.g. `nx build`, `nx g component`, etc. | | NX_HEAD | string | The default head branch to use when calculating the affected projects. Can be overridden on the command line with `--head`. | | NX_PERF_LOGGING | boolean | If set to `true`, will print debug information useful for for profiling executors and Nx itself | | NX_PROFILE | string | Prepend `NX_PROFILE=profile.json` before running targets with Nx to generate a file that be [loaded in Chrome dev tools](/troubleshooting/performance-profiling) to visualize the performance of Nx across multiple processes. | | NX_WORKSPACE_DATA_CACHE_DIRECTORY | string | The project graph cache and some other internal nx caches are stored in `.nx/workspace-data` by default. Set this variable to use a different directory. | | NX_PROJECT_GRAPH_MAX_WORKERS | number | The number of workers to use when calculating the project graph. | | NX_PARALLEL | number | The number of tasks Nx should run in parallel. Overrides any configured value inside nx.json | | NX_RUNNER | string | The name of task runner from the config to use. Can be overridden on the command line with `--runner`. Not read if `NX_TASKS_RUNNER` is set. | | NX_SKIP_NX_CACHE | boolean | Rerun the tasks even when the results are available in the cache | | NX_TASKS_RUNNER | string | The name of task runner from the config to use. Can be overridden on the command line with `--runner`. Preferred over `NX_RUNNER`. | | NX_TASKS_RUNNER_DYNAMIC_OUTPUT | boolean | If set to `false`, will use non-dynamic terminal output strategy (what you see in CI), even when you terminal can support the dynamic version | | NX_VERBOSE_LOGGING | boolean | If set to `true`, will print debug information useful for troubleshooting | | NX_DRY_RUN | boolean | If set to `true`, will perform a dry run of the generator. No files will be created and no packages will be installed. | | NX_INTERACTIVE | boolean | If set to `true`, will allow Nx to prompt you in the terminal to answer some further questions when running generators. | | NX_GENERATE_QUIET | boolean | If set to `true`, will prevent Nx logging file operations during generate | | NX_PREFER_TS_NODE | boolean | If set to `true`, Nx will use `ts-node` for local execution of plugins even if `@swc-node/register` is installed. | | NX_IGNORE_CYCLES | boolean | If set to `true`, Nx will ignore errors created by a task graph circular dependency. Can be overriden on the command line with `--nxIgnoreCycles` | | NX_BATCH_MODE | boolean | If set to `true`, Nx will run task(s) in batches for executors which support batches. | | NX_SKIP_LOG_GROUPING | boolean | If set to `true`, Nx will not group command's logs on CI. | | NX_MIGRATE_CLI_VERSION | string | The version of Nx to use for running the `nx migrate` command. If not set, it defaults to `latest`. | | NX_LOAD_DOT_ENV_FILES | boolean | If set to 'false', Nx will not load any environment files (e.g. `.local.env`, `.env.local`) | | NX_NATIVE_FILE_CACHE_DIRECTORY | string | The cache for native `.node` files is stored under a global temp directory by default. Set this variable to use a different directory. This is interpreted as an absolute path. | Nx will set the following environment variables so they can be accessible within the process even outside of executors and generators. | Property | Type | Description | | ---------------------------- | ------- | --------------------------------------------------------------------------------------------------------------------- | | NX_TASK_TARGET_PROJECT | string | Set to the project name of the task being run. Use this to tell which project is being run. | | NX_TASK_TARGET_TARGET | string | Set to the target name of the task being run. Use this to tell which target of the project is being run. | | NX_TASK_TARGET_CONFIGURATION | string | Set to the configuration name of the task being run. Use this to tell which configuration of the target is being run. | | NX_DRY_RUN | boolean | Set to `true` during dry runs of generators. Use this to avoid side effects during generators. | | NX_INTERACTIVE | boolean | Set to `false` when running generators with `--interactive=false`. Use this to prevent prompting during generators | [Nx Cloud Environment Variables](/ci/reference/env-vars) are listed on a dedicated page.
