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_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_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 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_RUNNER | string | The name of task runner from the config to use. Can be overridden on the command line with --runner. |
| 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 |
| 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 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 |
