I am pretty new to flutter.I just developed a reminder app.But that was mostly only front-end.But my next project I want to build a meat delivery service app.But this requires me to work on the backed as well.I have been getting pretty vague answers on the backend part of flutter.
Can anyone explain what like how exactly should I go with backend.I know Python for the start.Also you can use dart as well.I am confused.I just want to finish off things in the optiminum period of time.
I think you can use the App Write.io, this project is open-source and free, you can install the server and everything will free for you. Btw: App Write has the Flutter SDK. And this project has much big community
Can you more information from here
firebase is pretty good but you need to have an API. there is no other way to do backend without API. here is the whole documentation about restApi https://medium.com/swlh/restful-api-documentation-made-easy-with-swagger-and-openapi-6df7f26dcad

I am trying build an application that can run offline and online too. If the application is offline it must run with minimum functionality and if it get an internet it automatically push data online Any references or tutorials would be appreciated.
any references that can help me to achieve this.
Yes, surely that's possible and you already mentioned the tools: node.js and electron are suitable. Most electron apps do that (whatsapp and joplin directly come to my mind).
You can look in the source of those already available apps, but it might be difficult. I would start with the tutorial of electron and search for the features as "check internet connectivity" (i.e. here on stackoverflow)
Your question is a bit to broadly stated to help in detail.
Yes, surely that's possible. you can use the node.js and electronJs with Angular are suitable.
For Angular and NodeJs refer the below document:
Build a Basic CRUD App with Angular and Node
For ElectronJs refer the below demo project:
Electron Samples
Best luck !!
I am a new self-taught developer.
I have created a simple full stack app (learning management system) using PERN stack. Now, I want to deploy it to learn the end-to-end process of creating a web app. I have a plan to make incremental improvements in the app and add more functionality to make it usable.
While researching for deployment, I came across various posts that doesn't recommend using create-react-app for production ready React apps. Further, this official article from React recommends using some toolchains for deployment (I think it is another name for Frameworks or set of tools):
https://reactjs.org/docs/create-a-new-react-app.html
Another alternative is to optimize the code using Webpack etc. before deploying it. I am neither familiar with any React Framework nor much aware of performance optimization for PERN apps.
If I have to use a framework, then my existing code may not work. I may have to do complete review of the same to make it suitable for the framework.
What is the best way to deploy my PERN app which I can scale in the future. (I have partially understood the concept of client side and server side rendering. As of now, users have to login to use app. But in the future it will be like the users can see the page (to take advantage of SEO) but need to login in order to interact with the site).
Do I need to learn a framework? (In that case I may have to develop all the code in that framework to maintain compatibility). If this is the case, then I will be glad to know which one?
Or, is there other way to deploy fully-functional PERN apps ready to use by potential customers.
Eagerly looking for some answers as I am completely confused at this point.
I've been digging into the IBM Cloud Services, Watson and NLP. Just installed the CLI and tried with Node SDKs, and a starterkit, unfortunately I did not succeed by trying to get a sample code by default to understand how it works.
After that, I did some research get a better open minded approach to how actually I could use some of their free services to get started, but there's actually to vague information, even though the IBM Docs are pretty extensive and well written, it can get very confusing.
I would appreciate any open source repo, or working/live project that you are willing to share to make a better image in my mind about it IBM cloud services.
A few days ago I wrote a sample application using the Natural Language Understanding service. Check the source code here: https://github.com/watson-developer-cloud/natural-language-understanding-code-pattern
The README has instructions on how to get the apikey which is the way you will use to authenticate your API calls.
Since you are using Node.js you can start with the sample above and also look at this page: https://cloud.ibm.com/apidocs/natural-language-understanding/natural-language-understanding?code=node which includes examples for all the features in Node.js using the node-sdk: https://github.com/watson-developer-cloud/node-sdk/
I wrote an angularJS app (with nodeJS and ExpressJS as my server). My app is totally independent from the server (I used pouchDB for the data). I would like to create an app/package that can be run from a computer or tablet. How can I do that?
I'm sure there are already lot of questions/answers about this topic but I couldn't find the right solution so I apologize in advance!
Thanks
If you r looking for an full-stack framework, i can really recommend Ionic.
It is a framework, that contains it's own customizable ui-framework(build on sass bootstrap), it is build on cordova aka phonegap and makes it easy to deploy and test the code on android, ios, ... . It is also optimized for angularjs and offers for most functions a directive.
I really love it. I did write a blogpost in german: kkonstantin/ionic
Maybe take your existing frontend javascript code and make use of a css framework, to make it look great for all window sizes.
Like: Ratchet (build on bootstrap)
Then you just make use of Phonegap to deploy your html/css/javascript code to the plattforms.
I using the upcoming weekend to check two things off of my 2013 project list:
Give Cloud Development A Try
Try ANGULAR.JS
My game plan is to set up the MEAN stack on Nitrous.IO and then use the stack to complete one of the many Angularjs tutorial projects available online.
Questions:
I'd be interested in hearing if anyone has set up the MEAN stack on Nitrous or otherwise or if anyone is aware of any good blog post that go through the process for someone with little to no javascript development experience.
Also, if you have setup a MEAN stack are there any things you would do differently or are there any invaluable resources I should be aware of.
Some Resources I Found Useful:
I've been researching online for the past week and have uncovered some great resources, but it would be great to see what others have found or can suggest. Below are some links to some resources that I have come across that may be helpful to others:
Building Angular Start-up Stack - Toronto Meetup Stream
Egghead.io Offers some great Video tutorials on Angular
Google's Angular site has a wealth of info.
USC Linux User Group Youtube video on MEAN on Amazon AWS
Thanks in advance for any resources, insights or guidance.
Since you are starting on JavaScript I would suggest that you start simple. For example
Build a simple web site with Node.js and Express (no Angular, no Mongo).
Deploy it to the cloud.
Then add Angular and see how the structure changes when you use an MVC framework on the client side (e.g. your backend becomes a plain REST API).
Then, play with Node.js and Mongo probably outside your simple Node/Express/Angular app to get the hand of a NoSQL database and database access from Node.js (the fact that everything is async brings some interesting challenges for beginners)
Then integrate Mongo into your app.
Ok, here's how I successfully set-up the MEAN stack on Nitrous.IO.
First, many thanks to Valeri V. Karpov and his The Code Barbarian blog. In July he had a blog post titled Introduction to the MEAN Stack, Part One: Setting Up Your Tools. I primarily followed his article, only making adjustment dictated by the Nitrous cloud platform.
So here are the steps:
Create A Nitrous Box: Go to the Nitrous site and sign-up for an account. Please note the free account does not provide enough storage to accommodate the full MEAN Stack. You'll need at least a "Start" pricing plan - at $9.99 per month.
Create A Nodejs Box: Once you complete your registration and select a pricing plan, its time to create a Nodejs box. Follow the instructions on the Nitrous site. The box comes preconfigured Nodejs.
Install Mongodb: To install Mongodb on your box, go to the shell prompt and type: parts install mongodb You can confirm the installation was successful by typing parts start mongodb. To stop the mongodb server you type parts stop mongodb.
Confirm your Node & NPM Installations: Type node at the command prompt. You should see a > sign if node is installed correctly. You are now in the node shell. Type control-c to exit the shell. Type NPM at the prompt and you should see some usage information
Install Express: type npm install express -g The -g flag means the package will be installed so you can run it from the terminal. Note, if you are using the free box you will likely encounter errors during the Express installation as a result of you exceeded the allocated storage.
From here on you can follow Valeri's article at Step 4 Creating an ExpressJS application..
Good luck and enjoy.
Use Bitnami https://bitnami.com/stack/mean. I like it a lot, pretty simple and concise. In my case it was for Windows and it was a seamless experience
