Completions
Members, parameters, and enum values for every Apps Script service, ranked by what fits at the cursor.
Google Apps Script code completion
Autocomplete and IntelliSense for Google Apps Script
For people who write Apps Script at script.google.com: myFunction adds typed autocomplete, hover documentation, signature help, and diagnostics to the editor, so you get type checking without moving the project to a local IDE.
Inside the editor
What you see in the editor.
myFunction reads the code in the open editor files and checks it as you type. It does not run your script or save your editor text. Use it to find a member, understand a call, and correct a problem before you run the script.
Hover documentation
The signature, parameter types, return type, and service documentation for the symbol under the cursor.
Signature help
Overloads and the current argument position while you type a call.
Diagnostics
Type errors, calls that do not match the service, malformed literal values, and service calls inside loops, marked as you type.
Go to definition
Jump from a call to its definition in any file of the open project.
Quick fixes
Rule-based quick fixes for supported diagnostics, each with a preview. You choose whether to apply it.
Native editor and extension
Native editor and myFunction, side by side.
myFunction adds types generated from the Apps Script runtime for the built-in services, plus types for the advanced services you enable.
| Need | Native editor | With myFunction |
|---|---|---|
| Service completion | A list of member names. | Typed members with parameters and documentation, ranked by what fits at the cursor. |
| Type checking | Syntax errors. | Type checking against the Apps Script services your code calls. |
| Hover and signatures | Short member summaries and limited parameter hints. | Full signatures, typed parameter positions, return types, and a link to the service documentation. |
| Navigation | Limited to the current file. | Go to definition across every file in the open project. |
| Advanced services | No types for advanced services. | Types for each advanced service you enable in the project. |
What changes your code
Quick fixes apply only when you choose them.
Completions, diagnostics, hover documentation, signature help, navigation, and rule-based quick fixes are free without an account. Diagnostics run continuously as you edit. A quick fix changes your open script only when you apply it. You save and run the script in Apps Script.
