# Langchain Go
|
|
|
|
[Langchain Go](https://tmc.github.io/langchaingo/docs/) is a framework for developing data-aware applications powered by language models in Go.
|
|
|
|
You can use Qdrant as a vector store in Langchain Go.
|
|
|
|
## Setup
|
|
|
|
Install the `langchain-go` project dependency
|
|
|
|
```bash
|
|
go get -u github.com/tmc/langchaingo
|
|
```
|
|
|
|
## Usage
|
|
|
|
Before you use the following code sample, customize the following values for your configuration:
|
|
|
|
- `YOUR_QDRANT_REST_URL`: If you've set up Qdrant using the [Quick Start](/documentation/quick-start/) guide,
|
|
set this value to `http://localhost:6333`.
|
|
- `YOUR_COLLECTION_NAME`: Use our [Collections](/documentation/concepts/collections/) guide to create or
|
|
list collections.
|
|
|
|
```go
|
|
package main
|
|
|
|
import (
|
|
"log"
|
|
"net/url"
|
|
|
|
"github.com/tmc/langchaingo/embeddings"
|
|
"github.com/tmc/langchaingo/llms/openai"
|
|
"github.com/tmc/langchaingo/vectorstores/qdrant"
|
|
)
|
|
|
|
func main() {
|
|
llm, err: = openai.New()
|
|
if err != nil {
|
|
log.Fatal(err)
|
|
}
|
|
|
|
e, err: = embeddings.NewEmbedder(llm)
|
|
if err != nil {
|
|
log.Fatal(err)
|
|
}
|
|
|
|
url, err: = url.Parse("YOUR_QDRANT_REST_URL")
|
|
if err != nil {
|
|
log.Fatal(err)
|
|
}
|
|
|
|
store, err: = qdrant.New(
|
|
qdrant.WithURL( * url),
|
|
qdrant.WithCollectionName("YOUR_COLLECTION_NAME"),
|
|
qdrant.WithEmbedder(e),
|
|
)
|
|
if err != nil {
|
|
log.Fatal(err)
|
|
}
|
|
}
|
|
```
