                      systemjs Key Features

                      Loads System.register modules, the CSP-compatible SystemJS module format.

                      Support for loading bare specifier names with import maps via <script type="systemjs-importmap">.

                      Supports hooks for loader customization.

                      Tracing hooks and registry deletion API for reloading workflows.

                      Supports loading Wasm, CSS and JSON module types.

                      Includes the global loading extra for loading global scripts, useful for loading library dependencies traditionally loaded with script tags.

                      Loading System modules from disk (via file:// urls) or the network, with included caching that respects the Content-Type header.

                      Import Maps (via the applyImportMap api).

                      Tracing hooks and registry deletion API for reloading workflows.

                      Loading global modules with the included global loading extra.

                      AMD loading support (through Window.define which is created).

                      Named register supports System.register('name', ...) named bundles which can then be imported as System.import('name') (as well as AMD named define support)

                      Dynamic import maps support. This is currently a potential new standard feature.

                      Global loading support for loading global scripts and detecting the defined global as the default export. Useful for loading common library scripts from CDN like System.import('//unpkg.com/lodash').

                      Module Types .css, .wasm, .json module type loading support in line with the existing modules specifications.

                      craco's Github readme, states that it is supporting Create React App (CRA) 4.*. By this statement, I'm assuming CRA 5 is not officially supported by craco.

                      However, this repository utilizes both CRA 5 and craco (but I have not verified that it is working). Use this repository to compare your setup (after verifying that the linked repositry is working), and try different settings/configs to see if you get further.
