The Files action evaluates its options using , temporarily storing the resulting files and making them available via a randomized Mechanic URL.

This action is most useful in concert with , by which a task may take the resulting file URLs and pass them on to another service. Used by itself, this action can also be useful for quickly testing file generators.

Options

This action accepts a JSON object, whose keys are filenames and whose values are . In this way, many files may be defined and generated by a single Files action.

Result

In Mechanic, actions are performed after their originating task run concludes. Actions are not performed inline during the task's Liquid rendering.

To inspect and respond to the results of an HTTP action, add a task subscription to mechanic/actions/perform, allowing the action to re-invoke the task with the action result data.

Learn more:

A Files action returns an object having the same keys (i.e. filenames) as its input. Each value is an object, having the following properties:

File property

Description

expires_at

An ISO8601 timestamp, specifying when the file will expire

mime_type

name

The filename, as given in the original action options

size

The size of the generated file, in bytes

url

The URL at which this file will be available, until it expires

Example

This task generates a variety of files. It then re-invokes itself (via mechanic/actions/perform), sending an email containing links to each of the generated files.
