Compilation

The Builder uses the rollup JS API to compile and bundle your background functions.

​

Entrypoints

Each file in your defer folder should export a Defer background function as its default export.

Here are the requirements for those files:

• .js, .jsx, .ts, .tsx, .cjs, .cjsx, .cts, .ctsx, .mjs, .mjsx, .mts, .mtsx extensions are supported
• *.spec.*, *.test.*, *_spec.*, *_test.* files are ignored
• spec, test, specs, tests nested folders are skipped

​

Typescript

Version 4.x and 5.x are supported.

The Builder detects your version of TS and uses it to compile your background functions.

​

Supported files

• .json
• .jsx
• .md
• .txt
• .html
• .jpg, .jpeg, .png, .svg, etc

​

Bundles and Sourcemaps

Here are the characteristics of the output of the Builder:

• One bundle per function
• Tree shaking is performed to reduce bundle size
• Bundles are emitted under the commonJS format
• Sourcemaps are generated
