<Tab title="TypeScript">
The current Mem0 TypeScript `pgvector` adapter takes individual Postgres fields,
so parse `DATABASE_URL` before creating `Memory`.
Use the Neon `DATABASE_URL` directly with `connectionString`. Set `ssl` if your runtime needs an explicit TLS config object.
| Parameter | Description | Default |
| -------------------- | ---------------------------------------------- | -------------- |
| `connectionString` | Neon Postgres connection string. | Required |
| `ssl` | Optional TLS settings passed directly to `pg`. | Driver default |
| `collectionName` | Name for the vector collection. | `memories` |
| `dimension` | Vector dimension for Mem0 config. | Auto-detected |
| `embeddingModelDims` | Embedding model dimensions for table creation. | Required |
| `hnsw` | Enables HNSW indexing. | `false` |
**TLS note:** `ssl: true` is sufficient for most Neon connections since Neon uses valid certificates. Use `ssl: { rejectUnauthorized: false }` only when connecting through Neon's connection pooler on certain edge runtimes (e.g. Cloudflare Workers) that require it, or when your environment does not trust the Neon CA chain.
| Parameter | Description | Default |
| --- | --- | --- |
| `user` | Database user. | Required |
| `password` | Database password. | Required |
| `host` | Database host. | Required |
| `port` | Database port. | `5432` |
| `dbname` | Database name. | `vector_store` |
