svelte-sequential-preprocessor
A Svelte preprocessor that wraps preprocessors to force them to be called sequentially.
Overview
Svelte evaluates preprocessors by running all markup preprocessors first, then script and finally styles. Some preprocesses may not work if other preprocessors haven't been run. For example, svelte-image uses svelte.parse() internally, so svelte-preprocess needs to be run before if any scss is present.
Installation
Using npm:
$ npm i -D svelte-sequential-preprocessorUsage
