IDB version error

[academy-services]

Hi again

After modifying the schema of an IDB database a few times I get a connection error:
DOMException: The requested version (1) is less than the existing version (24).

In the docs, I can't see a way to specify the version?

Is there an ability to do so, or can it be included?

ta!

This should be taken care of automatically for you, here's the relevant code in the IndexedDB adapter:

let version = parseInt(localStorage.getItem(this._id + "-idb-version") || "") || 1;
const modelHash = localStorage.getItem(this._id + "-idb-hash") || this._modelHash;

if (modelHash !== this._modelHash) {
    version++;
}

localStorage.setItem(this._id + "-idb-version", String(version));
localStorage.setItem(this._id + "-idb-hash", this._modelHash);
indexedDB.open(this._id, version)

Basically the indexedDB version is stored in localStorage, then when the data model is updated the version is incremented. What happened in your case is likely a result of localStorage getting cleared out but not IndexedDB.

In any case, there's a new optional config property: idbVersion. If you pass it in the automatic code will be ignored and your manually provided version number will be used instead.

Update is live on NPM in v1.7.0.

Our company's group policy wipes cookies and localstorage after each session, hence the issue.

I implemented a workaround by checking for a connection outside of NanoSQL and incrementing the version number until we get a hit.

Thanks for the response. Loving NanoSQL!
