Function initializeFromEnv

initializeFromEnv(
env: Record<string, unknown>,
options?: InitializeFromEnvOptions,
): string[]
Initializes CollegeDB by discovering shard bindings from a Workers env.

On Cloudflare, D1 bindings live on env under conventional names (DB_EAST, DB_WEST, ...). This scans env for those, resolves each with toProvider (D1 / Drizzle / SQLite), wires the KV store (raw Workers KV is auto-wrapped via createWorkersKVProvider), and calls initialize. It removes the ~40-line hand-rolled wiring most Worker apps otherwise write.

Shard names are the binding name lowercased with _ replaced by - (DB_EAST -> db-east).
Parameters
- env: Record<string, unknown>
  The Worker environment bindings
- options: InitializeFromEnvOptions = {}
  KV/coordinator overrides, discovery prefixes, strategy, etc.
Returns string[]
The list of shard names that were registered
Throws
If no KV binding or no shard bindings can be resolved

Since
1.2.4
Example
```
import { sql } from 'drizzle-orm';

export default {
  async fetch(request, env) {
    if (!isInitialized()) {
      initializeFromEnv(env, { sql, strategy: { read: 'location', write: 'hash' } });
    }
    // ... routed queries
  }
};
```
