Code Examples

AWS Lambda Function Example

import pkg from '@apollo/client';
import { setContext } from '@apollo/client/link/context';
import { HttpLink } from '@apollo/client/link/http';
import jwt from 'jsonwebtoken';
import { createOneDocumentation } from 'lumic-backend-functions';

const { ApolloClient, InMemoryCache } = pkg;

// Your JWT secret and salt
const jwtSecret = process.env.JWT_SECRET || 'yourJwtSecret';
const jwtSalt = process.env.JWT_SALT || 'yourJwtSalt';

// Function to generate a JWT token using the secret and salt
const generateJwtToken = (secret, salt) => {
  return jwt.sign({ salt }, secret, { expiresIn: '1h' });
};

// Generate the JWT token
const token = generateJwtToken(jwtSecret, jwtSalt);

// HTTP Link to the GraphQL endpoint
const httpLink = new HttpLink({
  uri: process.env.GRAPHQL_ENDPOINT || 'https://your-graphql-endpoint.com',
});

// Set the authorization context with the JWT token
const authLink = setContext(async (_, { headers }) => {
  return {
    headers: {
      ...headers,
      authorization: token ? `Bearer ${token}` : "",
    }
  };
});

// Initialize the Apollo Client
const client = new ApolloClient({
  link: authLink.concat(httpLink),
  cache: new InMemoryCache(),
});

// Example of using the client within a Lambda function
export const handler = async (event) => {
  try {
    // Assuming `event` contains the necessary properties to create documentation
    const documentationData = {
      title: event.title,
      summary: event.summary,
      content: event.content,
      tagId: event.tagId,
      dependency: event.dependency,
      subsections: event.subsections,
      examples: event.examples,
      tags: event.tags,
      useCases: event.useCases
    };

    // Use the createOneDocumentation function with the Apollo Client instance
    const result = await createOneDocumentation(documentationData, client);

    return {
      statusCode: 200,
      body: JSON.stringify(result),
    };
  } catch (error) {
    console.error('Error:', error);
    return {
      statusCode: 500,
      body: JSON.stringify({ error: 'An error occurred' }),
    };
  }
};
