Mailgo in Next.js (and other SSR)

Mailgo is available also for Next.js and SSR

Next.js

Mailgo can be easily added to any Next.js project just modifying _app.js. You can check directly a repository of mailgo with Next.js (https://github.com/manzinello/next-mailgo) here the website deployed (thanks to Vercel): https://nextjs.mailgo.dev

import mailgo from "mailgo";

and simply add

useEffect(() => {
  mailgo();
}, []);

Here a complete example of a _app.js with a configuration (dark mode):

import { useEffect } from "react";

import "../styles/globals.css";

import mailgo from "mailgo";

const mailgoConfig = {
  dark: true,
};

function MyApp({ Component, pageProps }) {
  useEffect(() => {
    mailgo(mailgoConfig);
  }, []);

  return <Component {...pageProps} />;
}

export default MyApp;

Now mailgo is enabled in the entire web app!

Another running example (Next.js and also TypeScript) is my personal website: https://matteomanzinello.com

Other SSR

Install mailgo and then

import mailgo from "mailgo";

then you have to call mailgo(), IMPORTANT: do this when the object window is defined.

Here an example with React hooks:

useEffect(() => {
  mailgo();
}, []);

in this way you are sure that window is defined and mailgo will work correctly.

Another way (no hooks) is this:

componentDidMount() {
  mailgo();
}

You can pass to the function mailgo() also the configuration object.

BREAKING CHANGES from version 0.10.*: you can also use

const Mailgo = require("mailgo");

but then you have to call

Mailgo.start();

to start mailgo, here a complete example with Hooks:

const Mailgo = require("mailgo");

useEffect(() => {
  Mailgo.start();
}, []);

Mailgo can be installed in Gatsby through an official plugin: https://www.gatsbyjs.com/plugins/gatsby-plugin-mailgo/
