Sails.js

Your tech stack is solid for building a real-time messaging project.

React and React Native are excellent choices for the frontend, especially if you want to have both web and mobile versions of your application share code.

ExpressJS is an unopinionated framework that affords you the flexibility to use it's features at your term, which is a good start. However, I would recommend you explore Sails.js as well. Sails.js is built on top of Express.js and it provides additional features out of the box, especially the Websocket integration that your project requires.

Don't forget to set up Graphql codegen, this would improve your dev experience (Add Typescript, if you can too).

I don't know much about databases but you might want to consider using NO-SQL. I used Firebase real-time db and aws dynamo db on a few of my personal projects and I love they're easy to work with and offer more flexibility for a chat application.

We have an existing (Apis only) Rails backend, that by default follows the MVC pattern, (at peaks of 700 requests a second). I am tasked with making the same (read-heavy) application in any JavaScript framework. I was advised to follow the MVC structure. So I am considering these 3 ( Sails.js, LoopBack, NestJS). I get that sails is closest to rails, but that's not particularly a priority.

For a small mobile app that uses mostly localization, to display Google Maps with hotspots nearby, which Cross-Platform would you prefer and why? It will make requests to a Sails.js app.

Heya, I'm very new on here! And I hope I can get advice on this matter :

We are working on a new app. The web version is on Sails.js (V1)/node.js/vue.js. Started with the Web App default settings (including login and payments, which we are using use). We started with a web version to give access to the customer to start creating the data while building the mobile version. (iOS and Android)

I heard of Apache Cordova, that using the same JavaScript/css could be used to not re-code the front-end of the app for iPhones and Androids. I've been told that it is end-of-life now (? - I couldn't find this info myself).

I saw that Vue Native might be an alternative and would only need a few adjustments from our web version as we are using Vue.js for the frontend.

I know next to nothing on this, so I would really appreciate it if you guys could point me to possible solutions you've used and why instead of searching through all the existing solutions. (I'm very open to know if there are alternatives to those two too !!)

We will need to be using the GPS functions of the mobiles, which is a big part of the app.

Thank you!
