# Component
|
|
|
|
Components are the building blocks of the flows. They are made of inputs, outputs, and parameters that define their functionality, providing a convenient and straightforward way to compose LLM-based applications. Learn more about components and how they work in the LangChain [documentation](https://docs.langchain.com/docs/category/components) section.
|
|
|
|
### Component's Features
|
|
|
|
<div style={{ marginBottom: "20px" }}>
|
|
During the flow creation process, you will notice handles (colored circles)
|
|
attached to one or both sides of a component. These handles represent the
|
|
availability to connect to other components, while their colors are type hints
|
|
(hover over a handle to see connection details).
|
|
</div>
|
|
|
|
<div style={{ marginBottom: "20px" }}>
|
|
For example, if you select a <code>ConversationChain</code> component, you
|
|
will see orange <span style={{ color: "orange" }}>o</span> and purple{" "}
|
|
<span style={{ color: "purple" }}>o</span> input handles. They indicate that
|
|
this component accepts an LLM and a Memory component as inputs. The red
|
|
asterisk <span style={{ color: "red" }}>*</span> means that at least one input
|
|
of that type is required.
|
|
</div>
|
|
|
|
<div
|
|
style={{ marginBottom: "20px", display: "flex", justifyContent: "center" }}
|
|
>
|
|
<ZoomableImage
|
|
alt="Docusaurus themed image"
|
|
sources={{
|
|
light: useBaseUrl("img/single-compenent.png"),
|
|
}}
|
|
style={{ width: "100%", maxWidth: "800px", margin: "0 auto" }}
|
|
/>
|
|
</div>
|
|
|
|
<div style={{ marginBottom: "20px" }}>
|
|
On the top right corner, you will find the component status icon 🔴. Make the
|
|
necessary connections, build the flow (⚡ zap icon on the bottom right of the
|
|
canvas) and once the validation is completed, the status of each validated
|
|
component should light green 🟢. Hover over the component status to reveal the
|
|
outputs going through it in case of success, or the detected error in case of
|
|
failure.
|
|
</div>

### Component's Parameters
|
|
|
|
Langflow components can be edited in the component settings button. Hide parameters to reduce complexity and keep the canvas clean and intuitive for experimentation.
