Google API Wrapper

Install

Simple Wrapper around Google Sheets & Drive APIs

npm install google-api-wrapper

This will add googleapis as dependency.

Basic Usage

const Google = require('google-api-wrapper');

async function main() {
  Google.setCred(cred);
  Google.setToken(token);
  const sheet = Google.getSheet();
  const rows = await sheet.read('1nZqgw5otHxvg7by-qnYmjkyNdHAPQYgduv7Tbf5aKlw');
  console.log(rows);
}

main();

Set Credentials

Google.loadCredFile(credentails.json);
Google.loadTokenFile(token.json);

Or,

Google.setCred(cred);
Google.setToken(token);

Reading Sheet

await sheet.read(id, range = 'Sheet1');

Returns two-dimensional array of rows and column values of sheet data.

Writing Sheet

sheet.set(id, range = 'Sheet1');
await sheet.clear();
await sheet.write(row1);
await sheet.write(row2);
await sheet.endWrite();

Batches up multiple rows and then write once at interval of 500 rows, or when endWrite() is called.

Creating Sheet

await sheet.create(name);
await sheet.write([ 'hello', 'there' ]);
await sheet.create(name, folderId);

Get File Info by Id

const drive = Google.getDrive();
const file = drive.byId(fileId);

It returns a file object with { id, name, mimeType } attributes.

Get File Info by Name

drive.byName(name, type = null, folderId = null);

Example:

const drive = Google.getDrive();
let file;
file = drive.byName('My Document');
file = drive.byName('example.csv', 'type/csv', parentFolderId);
file = drive.byName('Example', null, parentFolderId);

It returns a file object with { id, name, mimeType } attributes.

List Files in a Folder

drive.list(folderId);

Example: to list all files under a folder named "My Folder"

const drive = Google.getDrive();
const folder = drive.byName('My Folder');
const files = drive.list(folder.id);

It returns an array of file objects with { id, name, mimeType } attributes.

Reading File (Raw)

const drive = Google.getDrive();
await drive.readFile(id);

Returns string of file content.

Move File

const drive = Google.getDrive();
await drive.move(fileId, folderId);

Unwrapping - Accessing underlying Google API Resources

drive object holds reference to Google API's drive object as a property. So to call the methods of Google Drive API.

For example, to list comments on a document named 'My Document', follow below

const Google = require('google-api-wrapper');
const drive = Google.getDrive();
const file = drive.byName('My Document');
// Below is call to underlying Google Drive API's method directly
const comments = drive.drive.comments.list({ fileId: file.id });

Similarly, Google Sheet object is stored as sheet property of wrapper's sheet object. methods on sheet.sheet can be made as per Google Sheet API.

const Google = require('google-api-wrapper');
const sheet = Google.getSheet();
// Calls underlying Google Sheet API
sheet.sheet.spreadsheets.batchGet(options);

Testing

To test the package,

• Create / download credentails.json file from Google Console.
• After OAuth2, capture the token returned in token.json file.
• Create .env file with path to these two files as below

# .env file
CRED_PATH=/path/to/credentials.json
TOKEN_PATH=/path/to/token.json

• run npm test
