create typescript code that creates a button that download a zip file that contains files from google storage and csv file from a postgres table using react, nodejs, graphql, prisma
user
Sure, I can help you with the basic structure for this task. However, this is a complex task, and there are many libraries and packages that you need to make it work. Here's a rough outline:

1. Start with a basic React app using `create-react-app`. This will generate all the necessary files and folders.

   ```bash
   npx create-react-app my-app --template typescript
   ```

2. Move to the React app directory and install the necessary dependencies using `npm`.

   ```bash
   cd my-app

   npm init -y

   npm install express graphql prisma nodemon
   ```

3. Create a `server` folder in your React app, then create a `server.ts` file inside it. This will be a GraphQL server that you'll call from your React component.

   ```typescript
   // server/server.ts

   import { ApolloServer, gql } from 'apollo-server';

   const resolvers = {
     Query: {
       async downloadZip() {
         // TODO: Download the zip file from Google Storage

         return 'Download completed!';
       },
     },
   };

   const typeDefs = gql`
     type Query {
       downloadZip: string,
     }
   `;

   const server = new ApolloServer({ typeDefs, resolvers });

   server.listen().then(({ url }) => {
     console.log(`🚀 Server ready at ${url}`);
   });
   ```

4. In the `tsconfig.json` file, add `"esModuleInterop": true` under the `compilerOptions` object.

5. Create a `index.tsx` file in the root of your React app. This will be your entry point for React, and it will import other files and render the download button.

   ```typescript
   // src/index.tsx

   import React from 'react';
   import { useQuery } from '@apollo/client';

   const DOWNLOAD_ZIP = gql`
     query {
       downloadZip
     }
   `;

   function Index() {
     const { loading, error, data } = useQuery(DOWNLOAD_ZIP);

     if (loading) return <p>Loading...</p>;
     if (error) return <p>Error :(</p>;

     return (
       <>
         <button onClick={() => alert(data?.downloadZip)}>Download</button>
       </>
     );
   }

   const App: React.FC = () => <Index />;

   export default App;
   ```

6. Start the GraphQL server using `nodemon server.js` in a new terminal tab.

7. Start the React app using `npm start` in the main terminal tab.

This is just the beginning. You'll need to set up your PostgreSQL database using Prisma and upload files on Google Cloud Storage as part of the functions. Also, you'll need to configure a CSV file in Posgres and configure the Prisma Client to read or write the file. After that, you may use the `fetch or axios` libraries to make a manual call to the API server.

Let me know if you need any more help on how to proceed.

create typescript code that creates a button that download a zip file that contains files from google storage and csv file from a postgres table using react, nodejs, graphql, prisma

To create a TypeScript code that creates a button to download a zip file containing files from Google Storage and a CSV file from a PostgreSQL table, you will need to set up a few components. Here's an outline of what you need to do:

1. Set up a Node.js server with GraphQL using Apollo Server.
2. Set up Prisma to connect to your PostgreSQL database.
3. Create a GraphQL query to fetch data from the PostgreSQL table and generate a CSV.
4. Create a Node.js function to download files from Google Storage.
5. Create a Node.js function to compress the downloaded files and CSV into a zip archive.
6. Create a React component to trigger the zip file download.

Here's the code to help you get started:

1. Set up Node.js server and dependencies:

```
mkdir my-app
cd my-app
npm init -y
npm install apollo-server express graphql prisma prisma-client-lib query-string csv-writer tensorflow zip-local
npm install --save-dev typescript ts-node nodemon @types/node @types/express @types/csv-writer @types/query-string
```

2. Create `tsconfig.json` for TypeScript configuration:

```json
{
  "compilerOptions": {
    "target": "es6",
    "module": "commonjs",
    "lib": ["es6", "dom"],
    "strict": true,
    "esModuleInterop": true,
    "skipLibCheck": true,
    "forceConsistentCasingInFileNames": true
  },
  "include": ["src"]
}
```

3. Create `nodemon.json` for nodemon configuration:

```json
{
  "watch": ["src"],
  "ext": "ts",
  "exec": "ts-node src/index.ts"
}
```

4. Create a `prisma` schema to connect to your PostgreSQL database in `prisma/schema.prisma`:

```prisma
datasource db {
  provider = "postgresql"
  url      = env("DATABASE_URL")
}

generator client {
  provider = "prisma-client-js"
}

model YourModel {
  id        Int      @id @default(autoincrement())
  column1   String
  column2   String
  /* ... any other columns you need */
}
```

5. Add the following code to `src/index.ts`:

```typescript
import express from 'express';
import { ApolloServer, gql } from 'apollo-server-express';
import { PrismaClient } from '@prisma/client';
import fetch from 'node-fetch';
import { createWriteStream, createReadStream } from 'fs';
import { pipeline } from 'stream';
import { promisify } from 'util';
import archiver from 'archiver';
import { GoogleAuth, JWT } from 'google-auth-library';
import * as queryString from 'query-string';
import { createObjectCsvWriter as createCsvWriter } from 'csv-writer';

const app = express();
const prisma = new PrismaClient();

(async () => {
  await prisma.$connect();

  // Set up GraphQL schema
  const typeDefs = gql`
    type Query {
      generateZipFile: String!
    }
  `;

  // Set up GraphQL resolvers
  const resolvers = {
    Query: {
      generateZipFile: async () => {
        // Generate CSV from PostgreSQL table
        const records = await prisma.yourModel.findMany();
        const csvWriter = createCsvWriter({
          path: 'output.csv',
          header: [
            { id: 'column1', title: 'COLUMN1' },
            { id: 'column2', title: 'COLUMN2' },
            /* ... any other columns you need */
          ],
        });

        await csvWriter.writeRecords(records);

        // Download files from Google Storage
        const auth = new GoogleAuth({
          scopes: 'https://www.googleapis.com/auth/devstorage.read_only',
        });

        const client = await auth.getIdTokenClient(serviceAccountEmail);
        const res = await client.request({
          url: `https://www.googleapis.com/storage/v1/b/your-bucket/o?fields=items(name)&filters=name%20gt%20%22%22`,
        });

        const fileUrls = res.data.items.map((item: any) => item.name);

        const zip = archiver('zip');
        const zipFileName = 'output.zip';
        const zipFile = createWriteStream(zipFileName);

        pipeline(zip, zipFile, (err) => {
          if (err) {
            console.error('Error creating zip file', err);
          } else {
            console.log('Zip file created successfully');
          }
        });

        zip.on('error', (err) => console.error('Error creating zip', err));

        // Download and add files to zip archive
        await Promise.all(
          fileUrls.map(async (fileUrl) => {
            const response = await fetch(fileUrl, {
              headers: {
                Authorization: `Bearer ${(
                  await client.getAccessToken()
                ).toString()}`,
              },
            });
            const readStream = createReadStream(fileUrl);
            const entryName = queryString.parseUrl(fileUrl).query.fields[0];
            zip.append(readStream, { name: entryName });
          })
        );

        zip.append('output.csv', { name: 'output.csv' });
        zip.finalize();

        return zipFileName;
      },
    },
  };

  const server = new ApolloServer({ typeDefs, resolvers });

  await server.start();
  server.applyMiddleware({ app });

  const port = process.env.PORT || 4000;
  app.listen(port, () => {
    console.log(`🚀 Server ready at http://localhost:${port}${server.graphqlPath}`);
  });
})();
```

6. Create a `package.json` script for starting the server:

```json
"scripts": {
  "start": "nodemon"
}
```

7. Create a React component in a separate folder (e.g., `client`), and use Apollo Client to query the GraphQL API:

```typescript
import React, { useEffect, useState } from 'react';
import { useQuery, gql } from '@apollo/client';
import { saveAs } from 'file-saver';

const GET_ZIP_FILE = gql`
  query GenerateZipFile {
    generateZipFile
  }
`;

const DownloadButton: React.FC = () => {
  const { data, loading } = useQuery(GET_ZIP_FILE);
  const [downloading, setDownloading] = useState(false);

  useEffect(() => {
    if (!loading && data && !downloading) {
      setDownloading(true);
      const fileName = data.generateZipFile;

      // Fetch zip file from your API
      fetch(`http://localhost:4000/api/download/${fileName}`, {
        method: 'GET',
      })
        .then((response) => response.blob())
        .then((blob) => {
          saveAs(blob, fileName);
          setDownloading(false);
        })
        .catch((error) => {
          console.log('Error downloading file', error);
          setDownloading(false);
        });
    }
  }, [loading, data, downloading]);

  return (
    <button disabled={loading || downloading} onClick={() => {}}>
      {loading || downloading ? 'Downloading...' : 'Download ZIP'}
    </button>
  );
};

export default DownloadButton;
```

Remember to set up your Google service account credentials and configure the Google Cloud Storage bucket name in the `src/index.ts` code.

This is just the beginning of your implementation. There may be some tweaks or adjustments you need to make to this code to fit your specific use case.
