Runtime Environment Presets

Configure a build task that applies environment variable presets from literal entries and runtime-evaluated functions, with a default task chaining both presets.

Capabilities

Static preset sets literal values

• After running the default task, process.env.APP_MODE equals static-mode because the static preset applies a literal entry. @test

Function-based values evaluate at runtime

• Running the dynamic preset twice in the same process yields two different values for process.env.RUN_ID, demonstrating the value is produced by a function executed each run. @test

Functions can combine prior env

• After the default task runs the static preset and then the dynamic preset, process.env.COMBINED_FLAG equals static-mode-combined, showing the function reads an existing env var during evaluation. @test

 * The default task runs the static preset first and the dynamic preset second.
 * @param {object} taskRunner - Build tool instance that supports task registration.
