# app
## Installation
Install the LangChain CLI if you haven't yet
```bash
pip install -U langchain-cli
```
## Adding packages
```bash
# adding packages from
# https://github.com/langchain-ai/langchain/tree/master/templates
langchain app add $PROJECT_NAME
# adding custom GitHub repo packages
langchain app add --repo $OWNER/$REPO
# or with whole git string (supports other git providers):
# langchain app add git+https://github.com/hwchase17/chain-of-verification
# with a custom api mount point (defaults to `/{package_name}`)
langchain app add $PROJECT_NAME --api_path=/my/custom/path/rag
```
Note: you remove packages by their api path
```bash
langchain app remove my/custom/path/rag
```
## Setup LangSmith (Optional)
LangSmith will help us trace, monitor and debug LangChain applications.
LangSmith is currently in private beta, you can sign up [here](https://smith.langchain.com/).
If you don't have access, you can skip this section
```shell
export LANGCHAIN_TRACING_V2=true
export LANGCHAIN_API_KEY=<your-api-key>
export LANGCHAIN_PROJECT=<your-project> # if not specified, defaults to "default"
```
## Launch LangServe
```bash
langchain serve
```
## Running in Docker
This project folder includes a Dockerfile that allows you to easily build and host your LangServe app.
### Building the Image
To build the image, you simply:
```shell
docker build . -t my-langserve-app
```
If you tag your image with something other than `my-langserve-app`,
note it for use in the next step.
### Running the Image Locally
To run the image, you'll need to include any environment variables
necessary for your application.
In the below example, we inject the `OPENAI_API_KEY` environment
variable with the value set in my local environment
(`$OPENAI_API_KEY`)
We also expose port 8080 with the `-p 8080:8080` option.
```shell
docker run -e OPENAI_API_KEY=$OPENAI_API_KEY -p 8080:8080 my-langserve-app
