I have developed my ethereum smart contract and I want to integrate it with my web application. But I don't know that is integration with ReactJS a better option or integration with nodejs a better one. Please give suggestions . Also I don't know how to do integration with backend through web3 library so please guide me about that.
When you are creating web3 app , most of the time you are not going to need a backend for that (Although you need a server to host your website) .
Working with and managing smart contracts are very easy at the front-end and there is no need for backend, but if your working on a large scale project , you are definitely going to need a backend for handling complex logics .
Next js is best option for both of that , containing node and react , also no need for manually configuring web server.
Better is next.js. I explained it here: https://ethereum.stackexchange.com/questions/129547/next-js-versus-react-which-to-use-when-for-your-dapp/130040#130040
Not every browser has metamask extension. By using next.js, when our
code is taken and rendered on the server, on the next server we can
reach out to the Ethereum network and do some initial calls like data
fetching, or alist of items in your smart contract. we execute all of
those requests on the server. That means when next.js produces Html
documents to send down to the user browser, it does not matter whether
or not users are using metamask. It does not matter whether or not
they have access to an Ethereum network. Because we already take care
of the data fetching for them. So all the users out there who are not
using metamask are going to see some information on the screen.
You've mentioned that you don't want to switch technologies, and while I agree with NextJS being a good platform to develop dApps on, I suggest you just use your current NodeJS server for anything that isn't web3 related and you use the web3js library from the frontend (your React) which would be very similar to a NextJS app anyway.
This way you don't have to switch technologies.
I'm a student who's newbie to the world of APIs and I'm working on an assignment where I have to create a NodeJs rest API that would call a SOAP service, transfer the XML response into a JSON object and return it to my angular project that calls this API.
I have looked around and found very little information about this, so is there a good place for me to start (Tutorial, courses, etc..) ?
looking forward to receiving answers because my passing grade is on the line :( </3
You need to break up this problem into multiple steps.
How do we make a rest-api in nodejs?
See a link like: https://www.codementor.io/#olatundegaruba/nodejs-restful-apis-in-10-minutes-q0sgsfhbd
OR How to best create a RESTful API in Node.js
How do we call a soap service from nodejs?
See e.g. SOAP Request using nodejs
How do we call our rest-api from angular?
https://angular.io/guide/http OR
Call Rest API From Angular Application
So break the problem up into steps, find the tutorials that help you implement that part, and put it all together.
Also use console.log and JSON.Stringify to debug your objects. E.g. see: https://levelup.gitconnected.com/5-ways-to-log-an-object-to-the-console-in-javascript-7b995c56af5a
I am new to Stackoverflow so please forgive me if my question is bit difficult to understand. However, background of my problem is following.
I have created a NodeJS RESTful API based on the following tutorial -
https://www.codementor.io/olatundegaruba/nodejs-restful-apis-in-10-minutes-q0sgsfhbd
I have also created a Vue based frontend what I use to display data from database with GET request, POST new data to database and also PATCH/DELETE requests.
I need to create a login/registration system to secure my api endpoints so that the unauthorized person cannot see/delete/modify the content but I have no idea where to start or how to implement it.
My project frontend and backend repositories are visible on:
Frontend - https://github.com/umbluu/mufc-api-fe
Backend - https://github.com/umbluu/mufc-api-be
Can someone please point out some hints/tips how to proceed with my task?
i was searching for first data gateway api and i am stuck with the lots of names.
what is the difference between.
firstdata
payeezy
FirstData_Connect
FirstData_Webservice
FirstData_Payeezy
are those all separate gateways. if yes. then do i have to integrate different api for all of them.
can anyone give me the api docs. link for all of them.
thanks.
First Data Connect and First Data Webservice API are integration methods for an older payment gateway that First Data is slowly phasing out. They've already phased out Connect. Payeezy is First Data's e-commerce gateway going forward.
I know this at least IMO is a stupid request. Because WSDL is old hat and sucks compared to just doing a RESTful API. But I have a corporate "mandate" where we want to do a REST API but then corporate wants a WSDL still. I know..it makes no sense and apparently we can't push back and say NO and tell them to just use our future REST API.
So can you generate a WSDL if I were to start creating a REST API with ServiceStack? Meaning I add uri attributes and such? So that I can "make them happy"?
I prefer not to use WCF, it's a nightmare with a ton of attributes and configuration to try and hack a RPC style web service to try and be RESTful. Obviously that doesn't work out too well.
SOAP along with REST is supported and you can have REST API along with soap wsdl. There are some recommendations posted in servicestack wiki that you can review and get started! You just need to implement the restful service and soap, json, xml etc are automatically supported.
