Sending emails via serverless 3rd parties in React Native

Another robust approach to sending emails in React Native will be with external third-party services. Instead of launching a user’s email app to send an email, we’ll start sending emails to users in the background. These can be registration emails, password resets or anything else that makes sense to be sent once triggered.

To perform such operations, we’ll need to set up triggers (e.g. when a user taps on a ‘register’ button) and a way to send emails based on them. There are several approaches here:

Using Firebase triggers + Zapier + SendGrid

In this approach, we’ll try to integrate three different tools together to enable email sending. 

First of all, set up your Firebase account either with the help of the official docs or with the dedicated 3rd party layer for Firebase for React Native. Like Firebase with your React Native project by adding your individual code as shown on the screenshot below.


Now, the idea will be to send emails only when a new child record is added to Firebase Realtime Database. You won’t be able to send emails directly when that happens but this is when Zapier comes in handy. It lets you trigger an email sending from e.g. SendGrid the moment a child object is added with one of its ‘zaps’.

Now, just set up a customized email template to be sent when a Zap is triggered and you’re done! For more details on setting things up, check out SendGrid’s tutorial.

Using Firebase Cloud Functions + e.g. Gmail + Nodemailer

As you can see above, Firebase can be used to trigger events based on actions users take in your React Native app. Since 2017, there’s also a way to send transactional emails without the poor experience of redirecting them to their email app. You can do it through the 3rd-parties such as Zapier.

Firebase Cloud SDK allows for sending these emails with a node library called nodemailer. For it to work, you also need to add an email account to handle the sending. The most straightforward approach is with another Google product – Gmail but you can also use tools for mass mailings such as SendGrid or Mailjet.

This quickstart demonstrates how to set up an Auth-triggered Cloud Function using the Firebase SDK for Cloud Functions.

Setting up your own server 

Finally, if you don’t want to rely on 3rd parties, you could set up your own backend to handle email sending. This is certainly more difficult and time-consuming but if you make it work, it could save you money and provide independence from other providers.

One approach to doing this could be with Nodemailer, which we already utilized in the previous example. Integrating it with React Native raises problems as you can’t use server-side modules in React Native as RN is solely client-side. React Native comes with a WebKit JS engine bundled and the latter one misses several features vital for sending emails, for example, support for sockets. If you were to use nodemailer, you would need to add your SMTP credentials to the device which is possible but, this time, raises security concerns.

The best way to go about it would be probably by setting up a proxy server to handle email sending away from the device. This would, however, require a lot more additional development without a guarantee of success. 

As you can see, this approach is far from perfect. Try it out, though, if the previous methods don’t appeal to you and let us know in the comments if you managed to build something reliable. We’re curious to know!

How native is React Native? | React Native vs Native App Development

If you are undertaking a mobile app development for your start-up or enterprise, you are likely wondering whether to use React Native. As a popular development framework, React Native helps you to develop near-native mobile apps. However, you are probably also wondering how close you can get to a native app by using React Native. How native is React Native?

In the article, we discuss the similarities between native mobile development and development using React Native. We also touch upon where they differ and how to bridge the gaps. Read on.

A brief introduction to React Native

Let’s briefly set the context first. We will briefly touch upon what React Native is and how it differs from earlier hybrid frameworks.

React Native is a popular JavaScript framework that Facebook has created. You can use this open-source framework to code natively rendering Android and iOS mobile apps. You can use it to develop web apps too.

Facebook has developed React Native based on React, its JavaScript library. The first release of React Native came in March 2015. At the time of writing this article, the latest stable release of React Native is 0.62.0, and it was released in March 2020.

Although relatively new, React Native has acquired a high degree of popularity. The “Stack Overflow Developer Survey 2019” report identifies it as the 8th most loved framework. Facebook, Walmart, and Bloomberg are some of the top companies that use React Native.

The popularity of React Native comes from its advantages. Some of its advantages are as follows:

  • Performance: It delivers optimal performance.
  • Cross-platform development: You can develop both Android and iOS apps with it. The reuse of code expedites development and reduces costs.
  • UI design: React Native enables you to design simple and responsive UI for your mobile app.
  • 3rd party plugins: This framework supports 3rd party plugins.
  • Developer community: A vibrant community of developers support React Native.

Why React Native is fundamentally different from earlier hybrid frameworks

Are you wondering whether React Native is just another of those hybrid frameworks like Ionic or Cordova? It’s not! React Native is fundamentally different from these earlier hybrid frameworks.

React Native is very close to native. Consider the following aspects as described on the React Native website:

  • Access to many native platforms features: The primitives of React Native render to native platform UI. This means that your React Native app will use many native platform APIs as native apps would do.
  • Near-native user experience: React Native provides several native components, and these are platform agnostic.
  • The ease of accessing native APIs: React Native uses a declarative UI paradigm. This enables React Native to interact easily with native platform APIs since React Native wraps existing native code.

Due to these factors, React Native offers many more advantages compared to those earlier hybrid frameworks. We now review them.
