falkordb Load a JavaScript UDF library
Register User-Defined Functions (UDFs) written in JavaScript with FalkorDB.
Usage
Use the falkor.register() function within JavaScript code to register UDFs, then load the library using the FalkorDB client.
Example
from falkordb import FalkorDB
db = FalkorDB(host='localhost', port=6379)
lib = "StringUtils"
script = """
function UpperCaseOdd(s) {
return s.split('')
.map((c, i) => i % 2 !== 0 ? c.toUpperCase() : c)
.join('');
};
falkor.register('UpperCaseOdd', UpperCaseOdd);
"""
db.udf_load(lib, script)
Notes
- UDFs must be written in JavaScript
- Use
falkor.register()to make functions available in Cypher queries - The library name (
lib) is used as a namespace for the functions - UDFs are stored in FalkorDB and persist across restarts
- UDFs must be pure functions without side effects
