Use built-in shortcuts

n8n provides built-in methods and variables for working with data and accessing n8n data. This section provides a reference of available methods and variables for use in expressions¹, with a short description.

警告

Availability in the expressions editor and the Code node

Not every method and variable in this reference works in the Code node. The Code node runs plain JavaScript against native Luxon, not n8n's expression engine, so any entry marked Source: Custom n8n functionality on a reference page (for example, DateTime.format()) is an n8n-only extension that may not exist, or may behave differently, in the Code node.

If code in the Code node throws ... is not a function, or silently produces the wrong result:

Check whether the method's reference entry is tagged Custom n8n functionality.
Look for a native Luxon or JavaScript equivalent. For example, use toFormat() instead of the n8n-only DateTime.format().
Watch for methods that exist in both places but with different signatures, such as DateTime.plus()/minus(): n8n's expression version accepts (amount, unit), while native Luxon's version only accepts a single Duration-like object ({ days: 7 }). Using the expression-style signature in the Code node won't error, but won't produce the expected result either.

All data transformation functions (the top-level helper functions listed in this section, such as $if() or $jmespath()) are only available in the expressions editor, not the Code node.

The Cookbook contains examples for some common tasks, including some Code node only functions.

Footnotes

In n8n, expressions allow you to populate node parameters dynamically by executing JavaScript code. Instead of providing a static value, you can use the n8n expression syntax to define the value using data from previous nodes, other workflows, or your n8n environment.
