| -------------------------------- | ------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| 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 `node_modules/.cache/nx` 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_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](/recipes/other/performance-profiling) to visualize the performance of Nx across multiple processes. |
| NX_PROJECT_GRAPH_CACHE_DIRECTORY | string  | The project graph cache is stored in `node_modules/.cache/nx` 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_SKIP_NX_CACHE                 | boolean | Rerun the tasks even when the results are available in the cache                                                                                                                                                             |
| 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                                                                                                                                                    |
