Adding ts-morph as a js-slang dependency caused some warnings to appear when building the frontend. This is a known issue when bundling TypeScript with webpack, and cannot be resolved on the js-slang side because the js-slang build does not include its dependencies and they are instead installed directly to the frontend node_modules folder. Fix is to add typescript.js to the webpack noParse config, and also increase the file size limit for caching.
