sqlite3 web demo

This demo can be used to open databases in different storage implementations and access modes (e.g. through shared or dedicated workers). To open a database, open the consule and run await open('name', 'storage', 'access'). Supported values for storage are:

opfs: Uses the Origin private file system
indexedDb: Uses a virtualized file system implemented by storing chunks in IndexedDB
inMemory: Only stores files in memory without persistence.

Supported values for access are:

throughSharedWorker: Open the database in a shared worker. Different tabs will use the same sqlite3 connection
throughDedicatedWorker: Open the database in a dedicated worker. Requires shared array buffers when used with OPFS, and there is no synchronization for IndexedDB in dedicated workers.
inCurrentContext: Open the database in the current context, without a worker

After opening a database, you can use execute in the console to run SQL on it, e.g:


let db = await open('test', 'inMemory', 'throughSharedWorker');
await execute(db, 'create table foo (bar);');
