Sheetable

A utility for reading & writing tables in spreadsheets using Google Apps Script

---

Install

npm install @dtrlanz/sheetable

Usage

The following examples assume you are building your project with a bundler that allows you to import modules (e.g., @dtrlanz/gas-bundler).

For an example setup, see the server-side code, client-side HTML, and build script of the included test app.

Server-side code

Import SpreadsheetServer and add the following top-level function to your code:

import { SpreadsheetServer } from "@dtrlanz/sheetable";

function processSpreadsheetRequest(req) {
    return new SpreadsheetServer().processRequest(req);
}

If you want to limit client access to a specific spreadsheet, pass that to the SpreadsheetServer constructor:

const spreadsheet = SpreadsheetApp.openByUrl(/* spreadsheet url */);

function processSpreadsheetRequest(req) {
    return new SpreadsheetServer(spreadsheet).processRequest(req);
}

Note: As always, if you are using a bundler that performs tree-shaking, you will need to ensure your top-level functions are not eliminated. You can do this by assigning to globalThis:

globalThis.processSpreadsheetRequest = processSpreadsheetRequest;

Client-side code

Import Table and create a class that defines the records in your table. You can then create new table using Table.create() or open a table from an existing spreadsheet using Table.open().

import { Table } from "@dtrlanz/sheetable";

class Person {
    firstName = "";
    lastName = "";
    dob = new Date(0);
}

const people = Table.create(Person);

For further customization, you will probably want to import some decorators as well:

import { Table, title, index } from "@dtrlanz/sheetable";

class Person {
    @index
    @title("ID")
    id = 0;

    @title("First name")
    firstName = "";

    @title("Last name")
    lastName = "";

    @title("Date of birth")
    dob = new Date(0);
}

const people = Table.create(Person);
