Concerns

• [ ] A concern is npm start throws Javascript heap out of memory error. (keyword: react start stuck at Starting the development server JavaScript heap out of memory) We needed to allow 8G of memory in order for the dev server to spin up.
  • An SO post describes that he examine each library/component one by one and fix it by fixing the syntax errors first. So maybe the first step is to resolve all the warnings. Do use --max_old_space_size=8192 to start the dev server and see all the warnings, then fix them one by one. Also consider update all the packages.
  • This SO points out it's the source map files that are too large and it causes such issue.
  • Also note that nom run deploy gives the below warning:

    The bundle size is significantly larger than recommended.
    Consider reducing it with code splitting: https://goo.gl/9VhYWB
    You can also analyze the project dependencies: https://goo.gl/LeUzfb

• [x] If we delete node_modules and package-lock.json, then npm i, the above memory issue went away
  • However, React now errors on Can't perform a React state update on an unmounted component... use useEffect()... even if all components mentioned in the error message does not use any state at all.
  • Refactored to solve the "Can't perform" error.
