IndexedDB Support (IE, Firefox)

[awwx]

IE and Firefox don't support Web SQL Database; adding IndexedDB support would allow these browsers to use data offline as well.

I've successfully used Lawnchair for an Angular project to persist client data. It abstracts IndexedDB, WebSQL, even window.name. This could be a potential solution to this issue.

If you want to dig in, after downloading the lawnchair files, you could create a lawnchair package:

Package.describe({
    summary: "Lawnchair local persistent database abstraction layer"
});

Package.on_use(function (api) {
    api.add_files([
        "Lawnchair.js",
        "webkit-sqlite.js",
        "indexed-db.js",
        "window-name.js",
        "dom.js"
    ], "client");

    api.export("Lawnchair");
});

And then probably within your package, api.use("lawnchair", ...) and create an instance like so:

db = new Lawnchair({
    name: "whatever",
    adapter: ["webkit-sqlite", "indexed-db", "window-name", "dom"]
}, function () {});

then do whatever you need to with db.

Additionally, you may need to add window = this; at the top of each of the lawnchair files (Lawnchair.js, dom.js, indexed-db.js, etc), and also remove the var keyword from var Lawnchair = function (options, callback) { in Lawnchair.js.

Hope this can help!

Thanks! But sadly a key-value store abstraction isn't enough for what offline data needs.
