# List of Blocks

Every block available in Fluxify, grouped by what it does. New to blocks? Start with the [Blocks Overview](./index.md) and [How Blocks Work](./how-they-work.md).

## Logic & Flow

Start the flow, choose paths, repeat, run in parallel, handle errors, and respond.

* [**Entrypoint**](./entrypoint.md): where every flow starts.
* [**If Condition**](./if-condition.md): go one way when a check is true, another when it is false.
* [**Switch**](./switch.md): pick one of several paths. The first matching case wins.
* [**For Loop**](./for-loop.md): repeat a chain a set number of times.
* [**For Each Loop**](./foreach-loop.md): run a chain once for every item in a list.
* [**Orchestrator**](./orchestrator.md): run several chains at the same time and collect the results.
* [**Retry**](./retry.md): run a chain again when it fails, with a wait between tries.
* [**Error Handler**](./error-handler.md): choose what happens when a block fails.
* [**Response**](./response.md): send the answer to the caller and end the flow.

## Data

Variables, lists, reshaping data, and your own JavaScript.

* [**Set Variable**](./set-var.md): save a value for later blocks in the same request.
* [**Get Variable**](./get-var.md): read a saved value back.
* [**Array Operations**](./array-operations.md): add to, remove from or filter a list in a variable.
* [**Transformer**](./transformer.md): reshape an object by renaming fields or with JavaScript.
* [**JS Runner**](./js-runner.md): write your own JavaScript.
  * [JS Runner examples](./js-runner-examples.md): ready-to-copy code.

## HTTP

Call other services, and read or set request details.

* [**HTTP Request**](./http-request.md): call an external API.
* [**Get HTTP Param**](./get-http-param.md): read a query or path value from the URL.
* [**Get HTTP Header**](./get-http-header.md): read a request header.
* [**Get HTTP Request Body**](./get-http-request-body.md): read the body the caller sent.
* [**Get Request Cookie**](./get-request-cookie.md): read a cookie from the request.
* [**Set HTTP Header**](./set-http-header.md): add a header to the response.
* [**Set HTTP Cookie**](./set-http-cookie.md): send a cookie with the response.

## Database

Read, write and group changes in SQL and MongoDB databases.

* [**DB Get All**](./db-get-all.md): fetch a list of records.
* [**DB Get Single**](./db-get-single.md): fetch one record.
* [**DB Row Exists**](./db-row-exists.md): branch on whether a record exists.
* [**DB Count**](./db-count.md): count the records that match.
* [**DB Insert**](./db-insert.md): add one record, or update it if it already exists.
* [**DB Insert Bulk**](./db-insert-bulk.md): add many records at once.
* [**DB Update**](./db-update.md): change existing records.
* [**DB Delete**](./db-delete.md): remove records.
* [**DB Transaction**](./db-transaction.md): make a group of changes succeed or fail together.
* [**Rollback Transaction**](./db-rollback.md): cancel the transaction and undo its changes.
* [**DB Native**](./db-native.md): run your own SQL from JavaScript.

Shared options used by several database blocks:

* [DB Conditions](./db-conditions.md): operators, groups, optional filters and custom conditions.
* [DB Joins](./db-joins.md): combine related tables.
* [DB Sorting and Paging](./db-paging-sorting.md): order records and read them page by page.

## Key-Value

Cache data and keep short-lived state.

* [**KV Operations**](./kv-operations.md): get, set or delete one key.
* [**KV Raw Connection**](./kv-raw.md): run any command against the store.

## Message Queues

Hand work to other services.

* [**Send Message**](./send-message.md): publish to Kafka, NATS, SQS or a Redis stream.

## Logging

See what your flows are doing.

* [**Console Log**](./console-log.md): print to the server logs.
* [**Cloud Logs**](./cloud-logs.md): send to a log service like Loki or OpenTelemetry.

## Utility

Helper blocks.

* [**Trigger Workflow**](./trigger-workflow.md): start a workflow now or later, and carry on.
* [**Sticky Note**](./sticky-note.md): add a note to the canvas.

## Custom Blocks

Build your own.

* [**Custom Blocks**](./custom-blocks.md): turn a group of blocks into one reusable block.
* [**Tutorial**](./custom-blocks-tutorial.md): build your first custom block step by step.
