gforms-submit v1.0.5

GForms Submit

Submit form data to Google Forms via JavaScript/TypeScript.

This project can be used to build simple serverless contact forms and mailing lists with very little overhead.

Installation

npm i gforms-submit

Usage

Create a new Google Form, click Preview, inspect the DOM, and retrieve the <form> action URL and form field name= attribute values from your Google Form.

import gformsSubmit from "gforms-submit";

// Replace this with your form's action URL
const gformActionUrl =
  "https://docs.google.com/forms/d/e/abcdefgh12345678-abcdefgh/formResponse";

// Replace the name attribute with your form field's
const emailFormData = {
  nameAttribute: "emailAddress",
  value: "test@example.com"
};

// Replace the name attribute with your form field's
const messageFormData = {
  nameAttribute: "entry.12345678901",
  value: "Hello! This is my message."
};

// You can have as many form data objects as you'd like!
const formDatas = [emailFormData, messageFormData];

gformsSubmit(gformActionUrl, formDatas)
  .then(() => {
    console.log("Sent!");
  })
  .catch(err => {
    console.log(err);
  });

CORS

Responses from Google's servers are blocked by modern browsers due to CORS restrictions. Because of this, there's no way to know whether or not the form submission succeeded, so all submissions are treated as successful. You will see a CORS error in the console, but the form will still receive the submission.

If you use/build a CORS proxy, you can turn on error handling for your request to the proxy server. Error responses can then be handled as you see fit.

You can specify handleErrors to turn on request error handling:

// ...
const handleErrors = true;
// Note: This will always fail if you're not using a proxy!
gformsSubmit(gformActionUrl, formDatas, handleErrors)
  .then(() => {
    console.log("Sent!");
  })
  .catch(err => {
    console.log(err);
  });

Axios

This project uses axios to make requests.

TypeScript Support

This project is written in TypeScript and compiled to JavaScript. Type definitions are available in dist/index.d.ts.

Form data is defined as type GFormData, like so:

import gformsSubmit, { GFormData } from "gforms-submit";

const emailFormData: GFormData = {
  nameAttribute: "emailAddress",
  value: "test@example.com"
};
