Load NocoBase data to DuckDB
Build a NocoBase to DuckDB pipeline with your coding agent. One prompt scaffolds it with the dltHub AI harness, plus the NocoBase API base URL, auth, endpoints, and incremental loading.
NocoBase is a scalable, open-source no-code development platform that provides comprehensive REST APIs for application and data management. Everything needed to build a working NocoBase → DuckDB pipeline is on this page: the API's base URL, authentication, endpoints, pagination and incremental field — plus a prompt that hands the whole job to your coding agent.
Build your NocoBase to DuckDB pipeline
Paste this prompt into Claude, Codex, or Cursor. The agent does the rest.
PromptRunuvx dlthub-init@latestto build a pipeline from NocoBase to DuckDB and run it on dltHub
That scaffolds a dltHub workspace and installs the dltHub AI harness — the project rules, the secrets-management skill, and the dlt MCP server your agent needs to work safely. From there it reads the NocoBase API, proposes the endpoints to load, then writes, runs and validates the pipeline while you review rather than type. Credentials are inspected through MCP tools, so your agent never reads secrets.toml itself. How the LLM-native workflow works →
Prefer to write it yourself? Every fact the agent uses is below.
NocoBase API at a glance
| Base URL | https://your-nocobase-instance.com/api |
| Example endpoint | GET api/{collectionName}:list |
| Records found at | data |
| Authentication | all requests require an Authorization header with a Bearer token — sent in the Authorization header, prefixed Bearer |
| Pagination | Page-number |
| API reference | https://docs.nocobase.com/integration/api-keys/usage |
These values come from the NocoBase API reference — the authoritative source if anything here looks out of date.
How do I authenticate with the NocoBase API?
API requests must include an Authorization header with the format 'Bearer <API_KEY>'.
1. Get your credentials
- Enable the built-in 'Auth: API Keys' plugin via the NocoBase system settings. 2. Create or assign a role with the required permissions for the collections you intend to access. 3. Navigate to the API Key management page within the system settings. 4. Click 'Add API Key', select the appropriate role, and submit. 5. Copy the generated API key immediately from the popup window, as it will not be accessible again for security reasons.
2. Add them to .dlt/secrets.toml
[sources.nocobase_source] api_key = "your_actual_api_key_here"
dlt reads this file automatically at runtime. With the harness, the setup-secrets skill prompts you for the values and never handles the raw credential in chat. For production, see setting up credentials with dlt.
What NocoBase data can I load into DuckDB?
These are the NocoBase endpoints dlt can load into DuckDB:
| Resource | Endpoint | Method | Data selector | Description |
|---|---|---|---|---|
| resources | /api/{collectionName}:list | GET | data | Query list data |
| resources | /api/{collectionName}:get/{id} | GET | data | Query single data |
| resources | /api/{collectionName}:create | POST | Create new record | |
| resources | /api/{collectionName}:update/{id} | POST | Update record | |
| resources | /api/{collectionName}:destroy/{id} | POST | Delete record |
How do I load only new NocoBase records?
The NocoBase API reference does not document a timestamp or sequence field for these endpoints, so there is nothing to advertise here as verified. Pick a field from the endpoints table above that increases with every write, then set it as the cursor_path.
{"name": "resources", "endpoint": { "path": "api/{collectionName}:list", # Replace with a field that increases on every write. "incremental": {"cursor_path": "REPLACE_ME", "initial_value": "2024-01-01T00:00:00Z"}, }}
On the first run dlt loads everything from initial_value; on every run after that it requests only what changed and appends with write_disposition="merge" if you set a primary key. See incremental loading.
What does the generated NocoBase pipeline look like?
A standard dlt REST API pipeline — the same code you would write by hand, loading /api/swagger:get and /{collectionName}:list from the NocoBase API into DuckDB:
import dlt from dlt.sources.rest_api import RESTAPIConfig, rest_api_resources @dlt.source def nocobase_source(api_key=dlt.secrets.value): config: RESTAPIConfig = { "client": { "base_url": "https://your-nocobase-instance.com/api", "auth": {"type": "bearer", "token": api_key}, }, "resources": [ {"name": "resources", "endpoint": {"path": "api/{collectionName}:list", "data_selector": "data"}}, {"name": "resources", "endpoint": {"path": "api/{collectionName}:get/{id}", "data_selector": "data"}} ], } yield from rest_api_resources(config) def load_nocobase_to_duckdb() -> None: pipeline = dlt.pipeline( pipeline_name="nocobase_pipeline", destination="duckdb", dataset_name="nocobase_data", ) load_info = pipeline.run(nocobase_source()) print(load_info) if __name__ == "__main__": load_nocobase_to_duckdb()
Run it with python nocobase_pipeline.py. The agent iterates on this until it loads cleanly — you review and approve, rather than write it from scratch.
How do I query NocoBase data in DuckDB?
dlt creates one table per resource. Query the loaded data with Python or SQL — or ask your agent to, through the MCP server's execute_sql_query tool.
Python (pandas DataFrame):
import dlt data = dlt.pipeline("nocobase_pipeline").dataset() df = data.resources.df() print(df.head())
SQL:
SELECT * FROM nocobase_data.resources LIMIT 10;
See querying your data with dataset and exploring it in marimo notebooks.
How do I deploy the NocoBase to DuckDB pipeline in production?
The pipeline runs locally, which is ideal for prototyping and one-off analysis. When you need it on a schedule, monitored on every load, and shared with your team, deploy the same dlt code on the dltHub platform — no infrastructure to maintain. The prompt above already ends with "run it on dltHub", so your agent can take it there directly.
- Deploy & schedule — run the pipeline as a managed job with automatic retries.
- Monitor — observable job queues, alerting, and load metrics for every run.
- Transform — promote raw NocoBase loads into governed, documented models.
- Visualize & share — explore data in notebooks and publish live dashboards instead of static screenshots.
What other destinations can I load NocoBase data to?
dlt loads into any of these — only the destination argument changes:
| Destination | Example value |
|---|---|
| PostgreSQL | "postgres" |
| BigQuery | "bigquery" |
| Snowflake | "snowflake" |
| Redshift | "redshift" |
| Databricks | "databricks" |
| Filesystem (S3, GCS, Azure) | "filesystem" |
Set dlt.pipeline(destination="snowflake") and add credentials in .dlt/secrets.toml. On the dltHub platform the same pipeline runs against a managed Iceberg lakehouse. See the full destinations list.
