This gist lists challenges you run into when building offline-first applications based on IndexedDB, including open-source libraries like Firebase, pouchdb and AWS amplify (more).
Note that some of the following issues affect only Safari. Out of the major browsers, Chrome's IndexedDB implementation is the best.
When this bug occurs, every time you use the indexeddb, the WAL file grows. Garbage collection doesn't seem to be working, so after a while, you end up with gigabytes of data.

| # enforce the style guide for new/modified code only, as opposed to | |
| # having to restyle everything or adding cops incrementally. It relies | |
| # on git to figure out which files to check. | |

| # Here are some options you can pass in addition to the ones in rubocop: | |
