Nodes
This page lists the environment variables configuration options for managing nodes1 in n8n, including specifying which nodes to load or exclude, importing built-in or external modules in the Code node, enabling community nodes, and configuring node-specific limits.
Nodes and community node settings
| Variable | Type | Default | Description |
|---|---|---|---|
N8N_COMMUNITY_PACKAGES_AUTH_TOKEN |
String | - | Authentication token for a private npm registry. Use with N8N_COMMUNITY_PACKAGES_REGISTRY to authenticate requests when installing community nodes from a private registry. |
N8N_COMMUNITY_PACKAGES_ENABLED |
Boolean | true |
Enables (true) or disables (false) the functionality to install and load community nodes. If set to false, neither verified nor unverified community packages will be available, regardless of their individual settings. |
N8N_COMMUNITY_PACKAGES_PREVENT_LOADING |
Boolean | false |
Prevents (true) or allows (false) loading installed community nodes on instance startup. Use this if a faulty node prevents the instance from starting. |
N8N_COMMUNITY_PACKAGES_REGISTRY |
String | https://registry.npmjs.org |
NPM registry URL to pull community packages from (license required). |
N8N_CUSTOM_EXTENSIONS |
String | - | Specify the path to directories containing your custom nodes. |
N8N_PYTHON_ENABLED |
Boolean | true |
Whether to enable Python execution on the Code node. |
N8N_UNVERIFIED_PACKAGES_ENABLED |
Boolean | true |
When N8N_COMMUNITY_PACKAGES_ENABLED is true, this variable controls whether to enable the installation and use of unverified community nodes from an NPM registry (true) or not (false). |
N8N_VERIFIED_PACKAGES_ENABLED |
Boolean | true |
When N8N_COMMUNITY_PACKAGES_ENABLED is true, this variable controls whether to show verified community nodes in the nodes panel for installation and use (true) or to hide them (false). |
NODE_FUNCTION_ALLOW_BUILTIN |
String | - | Permit users to import specific built-in modules in the Code node. Use \* to allow all. n8n disables importing modules by default. |
NODE_FUNCTION_ALLOW_EXTERNAL |
String | - | Permit users to import specific external modules (from n8n/node_modules) in the Code node. n8n disables importing modules by default. |
NODES_ERROR_TRIGGER_TYPE |
String | n8n-nodes-base.errorTrigger |
Specify which node type to use as Error Trigger. |
NODES_EXCLUDE |
Array of strings | [\"n8n-nodes-base.executeCommand\", \"n8n-nodes-base.localFileTrigger\"] |
Specify which nodes not to load. For example, to block nodes that can be a security risk if users aren't trustworthy: NODES_EXCLUDE: "[\"n8n-nodes-base.executeCommand\", \"@n8n/n8n-nodes-langchain.lmChatDeepSeek\"]". To enable all nodes, specify NODES_EXCLUDE: "[]". |
NODES_INCLUDE |
Array of strings | - | Specify which nodes to load. |
NODES_MERGE_SQL_SANDBOX_MEMORY_LIMIT_MB |
Number | 64 |
Memory limit in MB for the Merge node's SQL sandbox. Increase this if Combine by SQL fails with large datasets and your instance has enough memory available. |
Compression node settings
| Variable | Type | Default | Description |
|---|---|---|---|
N8N_COMPRESSION_NODE_MAX_DECOMPRESSED_SIZE_BYTES |
Number | 2147483648 |
Maximum total decompressed output size in bytes. Default is 2 GiB. |
N8N_COMPRESSION_NODE_MAX_ZIP_ENTRIES |
Number | 5000 |
Maximum number of entries allowed in a ZIP archive. |
Manage installed community packages
Pre-provision installed community packages from environment variables. See Manage instance settings using environment variables for the *_MANAGED_BY_ENV pattern.
| Variable | Type | Default | Description |
|---|---|---|---|
N8N_COMMUNITY_PACKAGES_MANAGED_BY_ENV |
Boolean | false |
Set to true to manage installed community packages from environment variables. When true, n8n reconciles the installed packages against N8N_COMMUNITY_PACKAGES on every startup, installing missing packages, correcting versions, and uninstalling any currently-installed packages that aren't in the list. The Community nodes settings page becomes read-only: you can't install, update, or uninstall packages from the UI while this is enabled. |
N8N_COMMUNITY_PACKAGES |
JSON string | - | JSON array of community packages to install. Each entry is an object with a name (required) and optional version and checksum fields. You can also embed the version in the name as <package-name>@<version>. See environment variable installation for the full per-field reference. |
Footnotes
- Back
In n8n, nodes are individual components that you compose to create workflows. Nodes define when the workflow should run, allow you to fetch, send, and process data, can define flow control logic, and connect with external services.
