Introduction

This npm package, drive-upload-service-account, provides functionality to upload files to Google Drive using service account authentication.

Installation

To install the package, use npm:

npm i drive-upload-service-account

Usage

First, import the required modules:

const express = require("express");
const multer = require("multer");
const cors = require("cors");
const { fileUploader } = require("drive-upload-service-account");

Then, set up your Express app:

const app = express();
const upload = multer();
app.use(upload.any());
app.use(cors());

Before using the package, you need to follow these steps:

1. Go to Google Cloud Console and enable the Google Drive API.
2. Navigate to Credentials in the Cloud Console.
3. Create service account credentials and download the JSON file.
4. Go to Google Drive and select the folder you want to store your data into.
5. In the URL https://drive.google.com/drive/u/0/folders/parentFolderId, use this parentFolderId in the parentId variable.

Define a route for file upload:

app.post("/upload", async (req, res) => {
  try {
    const keyFileLocation = "./path/to/key.json";
    const parentId = "folderID";
    const uploadedFiles = await fileUploader(
      keyFileLocation,
      parentId,
      req.files
    );
    res.json({ files: uploadedFiles });
  } catch (error) {
    res.status(500).json({ error: "Failed to upload files" });
  }
});

Finally, start the server:

app.listen(8080, () => {
  console.log(`Server is running on port 8080`);
});

To upload files from the frontend, you can use the following function:

const handleFileupload = async () => {
    const files = fileInputRef.current.files;
    if (files.length > 0) {
      const formData = new FormData();
      for (let i = 0; i < files.length; i++) {
        formData.append("files", files[i]);
      }
      try {
        const response = await fetch("http://localhost:8080/upload", {
          method: "POST",
          body: formData,
        });
        const data = await response.json();
        console.log("Uploaded files:", data.files);
      } catch (e) {
        console.log(e);
      }
    }
};
