Blocks Overview

Blocks are the building pieces of every Fluxify route and workflow. Each block does one job, like reading a database row, checking a condition, or sending a response. You connect blocks on the canvas, and data flows from one to the next.

Using a block

1. Drag a block from the sidebar onto the canvas.
2. Click it to set its fields in the side panel. The Docs tab there shows the page for that block.
3. Connect it to other blocks to decide what runs first, next, and on each path.

New to this? Read How Blocks Work first. It explains inputs, outputs and how data moves from block to block.

What you find on a block page

Every block page has the same parts, in the same order:

Section	What it tells you
Intro	What the block does, in one or two plain sentences.
When to use it	Real situations for it, and when to pick another block.
Inputs	Every field, whether it is required, and its default.
Outputs	What the next block receives, and which handles the block has (like Success and Failure).
Example	A small realistic setup with the settings and the result.
How it behaves	Edge cases, errors and anything surprising.
Related blocks	Blocks that are often used together with it.

Which block do I need?

I want to...	Use
Choose between two paths	If Condition
Choose between many paths	Switch
Repeat something	For Loop (a number of times) or For Each Loop (once per item)
Do several things at the same time	Orchestrator
Send an answer to the caller	Response
Handle a failure	Error Handler
Read what the caller sent	Get HTTP Request Body, Get HTTP Param, Get HTTP Header, Get Request Cookie
Call another web service	HTTP Request
Read or change data in a database	DB Get All, DB Get Single, DB Insert, DB Update, DB Delete
Change several records together, or none	DB Transaction
Remember a value for this request	Set Variable and Get Variable
Cache something between requests	KV Operations
Reshape data	Transformer
Write my own code	JS Runner
Run background work	Trigger Workflow
Log what happened	Console Log or Cloud Logs

Block groups

Group	What it covers
Logic & Flow	Start the flow, choose paths, repeat, run in parallel, handle errors, and respond.
Data	Variables, lists, reshaping data, and your own JavaScript.
HTTP	Call other services, and read or set request details like headers and cookies.
Database	Read, write and group changes in SQL and MongoDB databases.
Key-Value	Cache and short-lived state in Redis or Memcached.
Logging	Print to the server logs or send to a log service.
Utility	Start workflows, and add notes to the canvas.
Custom Blocks	Turn a group of blocks into one reusable block.
