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.

# Allows usage of all builtin modules <a href="#allows-usage-of-all-builtin-modules" id="allows-usage-of-all-builtin-modules"></a>
export NODE_FUNCTION_ALLOW_BUILTIN=*

# Allows usage of only crypto <a href="#allows-usage-of-only-crypto" id="allows-usage-of-only-crypto"></a>
export NODE_FUNCTION_ALLOW_BUILTIN=crypto

# Allows usage of only crypto and fs <a href="#allows-usage-of-only-crypto-and-fs" id="allows-usage-of-only-crypto-and-fs"></a>
export NODE_FUNCTION_ALLOW_BUILTIN=crypto,fs

# Allow usage of external npm modules. <a href="#allow-usage-of-external-npm-modules" id="allow-usage-of-external-npm-modules"></a>
export NODE_FUNCTION_ALLOW_EXTERNAL=moment,lodash

If using Task Runners

If n8n instance is setup with Task Runners, add the environment variables to the Task Runners instead to the main n8n node.

Refer to Environment variables reference for more information on these variables.
