|

<p>Anyone can contribute an example component. For example, if you created a new document loader called <strong>MyCustomDocumentLoader</strong>, you can follow these steps to contribute it to Langflow.</p>
|
||
<ol>
|
||
<li>Write your loader as an object of the <a href="https://github.com/langflow-ai/langflow/blob/dev/src/backend/base/langflow/custom/custom_component/custom_component.py" target="_blank" rel="noopener noreferrer">CustomComponent</a> class. You'll create a new class, <code>MyCustomDocumentLoader</code>, that will inherit from <code>CustomComponent</code> and override the base class's methods.</li>
|
||
<li>Define optional attributes like <code>display_name</code>, <code>description</code>, and <code>documentation</code> to provide information about your custom component.</li>
|
||
<li>Implement the <code>build_config</code> method to define the configuration options for your custom component.</li>
|
||
<li>Implement the <code>build</code> method to define the logic for taking input parameters specified in the <code>build_config</code> method and returning the desired output.</li>
|
||
<li>Add the code to the <a href="https://github.com/langflow-ai/langflow/tree/dev/src/backend/base/langflow/components" target="_blank" rel="noopener noreferrer">/components/documentloaders</a> folder.</li>
|
||
<li>Add the dependency to <a href="https://github.com/langflow-ai/langflow/blob/dev/src/backend/base/langflow/components/documentloaders/__init__.py" target="_blank" rel="noopener noreferrer">/documentloaders/<strong>init</strong>.py</a> as <code>from .MyCustomDocumentLoader import MyCustomDocumentLoader</code>.</li>
|
||
<li>Add any new dependencies to the <a href="https://github.com/langflow-ai/langflow/blob/main/pyproject.toml#L148" target="_blank" rel="noopener noreferrer">pyproject.toml</a> file.</li>
|
||
<li>Submit documentation for your component. For this example, you'd submit documentation to the <a href="https://github.com/langflow-ai/langflow/blob/main/docs/docs/Components/components-loaders.md" target="_blank" rel="noopener noreferrer">loaders page</a>.</li>
|
||
<li>Submit your changes as a pull request. The Langflow team will have a look, suggest changes, and add your component to Langflow.</li>
