Updated titles into a consistent format. Fixed links to the diagrams. Fixed typos. Note: The Templates menu in the navbar is now sorted by the file names. I'll try sorting the navbar menus by the page titles, not the page file names.

# Plate chain
|
|
|
|
This template enables parsing of data from `laboratory plates`.
|
|
|
|
In the context of biochemistry or molecular biology, laboratory plates are commonly used tools to hold samples in a grid-like format.
|
|
|
|
This can parse the resulting data into standardized (e.g., `JSON`) format for further processing.
|
|
|
|
## Environment Setup
|
|
|
|
Set the `OPENAI_API_KEY` environment variable to access the OpenAI models.
|
|
|
|
## Usage
|
|
|
|
To utilize plate-chain, you must have the LangChain CLI installed:
|
|
|
|
```shell
|
|
pip install -U langchain-cli
|
|
```
|
|
|
|
Creating a new LangChain project and installing plate-chain as the only package can be done with:
|
|
|
|
```shell
|
|
langchain app new my-app --package plate-chain
|
|
```
|
|
|
|
If you wish to add this to an existing project, simply run:
|
|
|
|
```shell
|
|
langchain app add plate-chain
|
|
```
|
|
|
|
Then add the following code to your `server.py` file:
|
|
|
|
```python
|
|
from plate_chain import chain as plate_chain
|
|
|
|
add_routes(app, plate_chain, path="/plate-chain")
|
|
```
|
|
|
|
(Optional) For configuring LangSmith, which helps trace, monitor and debug LangChain applications, use the following code:
|
|
|
|
```shell
|
|
export LANGCHAIN_TRACING_V2=true
|
|
export LANGCHAIN_API_KEY=<your-api-key>
|
|
export LANGCHAIN_PROJECT=<your-project> # if not specified, defaults to "default"
|
|
```
|
|
|
|
If you're in this directory, you can start a LangServe instance directly by:
|
|
|
|
```shell
|
|
langchain serve
|
|
```
|
|
|
|
This starts the FastAPI app with a server running locally at
|
|
[http://localhost:8000](http://localhost:8000)
|
|
|
|
All templates can be viewed at [http://127.0.0.1:8000/docs](http://127.0.0.1:8000/docs)
|
|
Access the playground at [http://127.0.0.1:8000/plate-chain/playground](http://127.0.0.1:8000/plate-chain/playground)
|
|
|
|
You can access the template from code with:
|
|
|
|
```python
|
|
from langserve.client import RemoteRunnable
|
|
|
|
runnable = RemoteRunnable("http://localhost:8000/plate-chain")
|
|
``` |
