Your challenge is to modify another pre-written file to add yourself as an actor in The Matrix.
Steps
-
Update the
paramsobject to use your name. This step isn’t strictly required, just a bit of fun. -
The Cypher statement is already written for you. Call the
session.executeWrite()method, passing a callback function to represent the unit of work. -
In that function you must call the
run()method on the first parameter passed to the function, using thecypherandparamsvariables. -
awaitthe results and useconsole.logto check that the code has executed correctly. -
To add the new node and relationship to the database, click the Debug icon to the left of the window and run Writing Data Challenge task, or use the integrated terminal window to run the following command:
shRun The Challengets-node src/challenges/write/challenge.ts -
Once the code has run, click Verify and we will check that the node has been added to the database.
Verifying the Test
Once you have executed the code, click the Verify button and we will check that the code has been executed successfully.
Hint
To pass this challenge you must run the Cypher statement in a write transaction using the session.executeWrite() method.
