  • How many lines of code you have in that component? Aug 25, 2020 at 12:33
  • more than 3000 lines Aug 25, 2020 at 12:36
  • Looks like you're trying to take in more information than you have allocated memory for. You will need to refactor your code to work in batches of information instead of the entire collection at once.

Each source file is limited to 131kb (2^17 characters). You will need to make smaller components/files in order to deploy your component. Components should be small and reusable. Entire applications should not be coded into a single component.

  • usually const = []; declaration consume more characters any ways to break the const declaration in seperate components or files? Aug 25, 2020 at 16:24
  • @Nirmal Include the structure in a secondary JS file, then import it: import FIELDLIST from './fieldlist.js'; const FIELDS = FIELDLIST; should work.

    @Rival You can indeed have multiple js files in a component package and import the methods via normal import statements. I'm actually designing some components right now that have that design, it works well.
