Console

Capture errors and debugging information in your functions

The Modus Console API allows you to capture information from your functions, such as errors and other information that can help you debug your functions.

Unlike other APIs, the Console API is globally available by default in all functions, you don’t need to import it.

The Console API mimics the behavior of the AssemblyScript console object, but directs the output to Hypermode as follows:

• All console output is available in the runtime logs. When hosting on Hypermode, the logs are available in the “Function Runs” section of the Console UI.
• Output from console.error is also sent to the GraphQL response.
• Errors thrown with the throw keyword are also sent to the GraphQL response.

Console APIs

The APIs in the console namespace are below, organized by category.

We’re constantly introducing new APIs through ongoing development with early users. Open an issue if you have ideas on what would make Modus even more powerful for your next app!
