Basic Usage

_Simple example to show some of the things you can do._

``javascript
var googlesheets = require("google-sheets-manager");
var creds = require("./client_secret.json");

var ServiceAccount = googlesheets.ServiceAccount;
var GoogleSheet = googlesheets.GoogleSheet;

const GOOGLE_SPREADSHEETID = ''; // update placeholder value
const GOOGLE_SHEETID = 0; // update placeholder value

var authClass = new ServiceAccount(creds);
var sheetAPI = new GoogleSheet(authClass, GOOGLE_SPREADSHEETID, GOOGLE_SHEETID);

var defaultCallback = (err, res) => {
if (err) {
throw err;
}
console.log(res);
};

sheetAPI.getData(defaultCallback);

sheetAPI.getData({
range: {
startRow: 2,
startCol: 1,
endRow: 3,
endCol: 2,
},
majorDimension: "COLUMNS",
}, defaultCallback);

sheetAPI.getBatchData(defaultCallback);

sheetAPI.getBatchData({
ranges: [{
startRow: 2,
startCol: 1,
endRow: 3,
endCol: 2,
}, {
startRow:2,
endCol: 1,
}],
majorDimension: "COLUMNS",
}, defaultCallback);

sheetAPI.setData([
['1', '2'],
['3', '4'],
], defaultCallback);

sheetAPI.setData([
['1', '2'],
['3', '4'],
], {
range: {
startRow: 2,
startCol: 1,
endRow: 3,
endCol: 2,
},
majorDimension: "COLUMNS",
}, defaultCallback);

Authentication

$3

This is a 2-legged oauth method and designed to be "an account that belongs to your application instead of to an individual end user".
Use this for an app that needs to access a set of documents that you have full access to.

__Setup Instructions__

1. Go to the Google Developers Console
2. Select your project or create a new one (and then select it)
3. Enable the Sheets API for your project
- In the sidebar on the left, expand __APIs & auth__ > __APIs__
- Search for "sheets"
- Click on "Sheets API"
- click the blue "Enable API" button
4. Create a service account for your project
- In the sidebar on the left, expand __APIs & auth__ > __Credentials__
- Click blue "Add credentials" button
- Select the "Service account" option
- Select "Furnish a new private key" checkbox
- Select the "JSON" key type option
- Click blue "Create" button
- your JSON key file is generated and downloaded to your machine (__it is the only copy!__)
- note your service account's email address (also available in the JSON key file)
5. Share the doc (or docs) with your service account using the email noted above

API

This module follows "normal" node callback conventions:

- Every method that takes a callback takes it as its last param
- Every callback will be called with the error (or null) as first param
- Some methods have optional params

$3

Wrapper class for simplifing authentication process using service account method

$3

- creds object - service account credentials loaded as json object _(see setup instruction above)_
- googleAuthScopes string[] - google scopes which you want to give the api access on, default value is scopes (["https://www.googleapis.com/auth/spreadsheets"])

----------------------------------




$3

Represents a single "sheet" from the spreadsheet. These are the different tabs/pages visible at the bottom of the Google Sheets interface.

sheets info returned as property sheets when calling GoogleSheet.getInfo.

__Properties:__
- spreadsheetId number - the ID of the main spreadsheet, could be extracted from sheet's url using this regex /spreadsheets/d/([a-zA-Z0-9-_]+)
- sheetId number - the ID of the single sheet tab, could be extracted from sheet's url using this regex [#&]gid=([0-9]+)

$3

- authClass AuthClass - instance of AuthClass inhereted class, like ServiceAccount
- spreadsheetId number - the ID of the main spreadsheet
- sheetId number - the ID of the single sheet tab, default value is 0

----------------------------------
