In this section, we will be installing the @winglibs/bedrock package and playing with it locally.

Create a New Project

# Create a fresh new project
mkdir /tmp/wing-bedrock-workshop

# Create a package.json file
cd /tmp/wing-bedrock-workshop
npm init --yes

Install @winglibs/bedrock

Install @winglibs/bedrock:

npm install --save @winglibs/bedrock

Let's Use the Bedrock Module

Create the following bedrock.main.w file:

bring cloud;
bring bedrock;

let claude = new bedrock.Model("anthropic.claude-v2:1") as "claude";

new cloud.Function(inflight (topic: str) => {
  let res = claude.invoke({
    prompt: "\n\nHuman: Tell me a joke about {topic}\n\nAssistant:",
    max_tokens_to_sample: 300,
    temperature: 0.5,
    top_k: 250,
    top_p: 1,
    stop_sequences: [
      "\n\nHuman:"
    ],
    anthropic_version: "bedrock-2023-05-31"
   });
  let joke = res.get("completion").asStr();
  log(joke);
  return joke;
});

Run the above code:

wing run bedrock.main.w

Now you can invoke the cloud.Function and provide it with a joke topic, using the Invoke button.

Challenge

Are you able to create a Prompt that will accept a markdown files and return a markdown file with perfect English?

🚀 We will later use the bedrock module to fix the grammar of markdown files, but first, let's create a GitHub app. 🚀
