# Enable modules in Code node
|
|
|
|
For security reasons, the Code node restricts importing modules. It's possible to lift that restriction for built-in and external modules by setting the following environment variables:
|
|
|
|
- `NODE_FUNCTION_ALLOW_BUILTIN`: For built-in modules
|
|
- `NODE_FUNCTION_ALLOW_EXTERNAL`: For external modules sourced from n8n/node_modules directory. External module support is disabled when an environment variable isn't set.
|
|
|
|
```bash
|
|
# Allows usage of all builtin modules
|
|
export NODE_FUNCTION_ALLOW_BUILTIN=*
|
|
|
|
# Allows usage of only crypto
|
|
export NODE_FUNCTION_ALLOW_BUILTIN=crypto
|
|
|
|
# Allows usage of only crypto and fs
|
|
export NODE_FUNCTION_ALLOW_BUILTIN=crypto,fs
|
|
|
|
# Allow usage of external npm modules.
|
|
export NODE_FUNCTION_ALLOW_EXTERNAL=moment,lodash
|
|
```
|
|
Refer to [Environment variables reference](/hosting/configuration/environment-variables/nodes/) for more information on these variables.
