r/webdev on Reddit: Doing an API request in the frontend or backend? What's best practices?
February 5, 2022 -
I was wondering because someone told me not to expose your keys in the front end even if you store it in an env file. But if you do the api request in the backend you have to do another axios request to get it in the front end. So anyone know what's the right or best method? 2 request for more security vs just 1?

What they mean is you normally need a service of your own to sit between your front end, and other 3rd party apis. So your front end calls your own back end. Your back end can use API keys and secrets safely to gather data from 3rd parties. Some APIs provide access tokens to fetch data directly from the front end. These apis usually don't serve sensitive information. Only information that would be public anyways. Like product info would be ok, but customer info might not. This is common in Shopify where you have an "admin" API and a storefront API It's safe to use the storefront API and expose your storefront access token, which can be regenerated anytime, and you can only access information related to showing your products on a website, or game. But their admin API should only be accessed by service that doesn't expose the API key and secret, like another back end service.

I would recommend to use a templating engine like handlebars or ejs.There are tons of examples for it, and sending data from backend to frontend becomes a piece of cake when using any templating engine. my personal favourite is handlebars because of its simple syntax.

It is advisable not to use document.querySelector if you're using Angular or React. React/Angular will have the browser repaint the DOM by making updates in the "root" div element of the index.html file whenever there is new data available to update. Also, why do you want to send a HTML file? You could have a route in Node like below
route.get('/weather', (req, res) => {
// do your api call with axios to get weather data
res.json(weatherData);
});
from your front-end you could make an API call to '/weather' route and consume the JSON data
axios.get('baseUrl/weather').then(res=>{
console.log("weather data", res);
}).catch(...);
You could also fetch weather data directly from front-end like above.

Question: How does the front-end integrate with the back-end in programming?
On July 1st, a change to Reddit's API pricing will come into effect. Several developers of commercial third-party apps have announced that this change will compel them to shut down their apps. At least one accessibility-focused non-commercial third party app will continue to be available free of charge. If you want to express your strong disagreement with the API pricing change or with Reddit's response to the backlash, you may want to consider the following options: Limiting your involvement with Reddit, or Temporarily refraining from using Reddit Cancelling your subscription of Reddit Premium as a way to voice your protest.

September 24, 2020 - A promise is a special JavaScript Object, that will allow us to receive our data from the fetch request if it is successful or execute some snippet of code if the requested data fails to get back to us. Since our fetch returns a promise object, we have access to the following three methods: .then(callback) which is is used when the promise is fulfilled (success)

November 21, 2023 - Choose a backend framework or technology such as Node.js with Express or Django for Python. Define routes and endpoints for your API using the chosen framework. Implement business logic and database operations within the API endpoints. Use JavaScript’s fetch API or libraries like Axios to send HTTP requests from the frontend.

It depends on what your 3rd party API requires.
If you need some credentials to call the API it's probably better to handle the call in backend because of security concerns.
If the API delivers time sensitive data, like some auto-complete information as you type, it might be good to not do the extra roundtrip to the backend and call it from the frontend.
You might create a subdomain which points to the 3rd party server, like 3rdparty-api.yourdomain.com, this removes a lot of cross-domain issues. But this needs cooperation of your 3rd party provider.
So, there is no clear yes or no answer but it depends on the situation and focus of your API.

I would say we should also take care about code duplication. In your case you are all JavaScript, but that is not true for many others. So let's say I consume api.github.com so I will not want to make some calls from frontend and some from the backend, then I think creating a controller which will handle all of this is a good choice.
Except for the cases like any analytics or tracking software, an extra round trip is ok.
As @Wolffc said, this can also prevent sending access_token to the browser which may be misused.

July 28, 2023 -
I get that HTML, CSS, and Javascript are front-end languages, but how do we connect the back-end and front-end?
I’ve been using R recently and an R-library called Shiny to help make basic webpages out of my R code. I was wondering how that compares to all these other tools for other languages that all seem related to this front-end/back-end integration.
I've heard React, Django, Angular, Node.js, Vue.js, Express.js, jQuery, etc. get thrown around and I don't really what they are.
In short, what are they? Are they libraries? Programs? How do they compare to Shiny? How do they relate to each other? Thanks!
Bonus questions: PHP vs. HTML/CSS/JS, and what is an API

So, Javascript can be both a backend and frontend language. Node is a javascript runtime and it's what allows you to run javascript in a server instead of just on the browser. React, Angular and Vue are javascript frameworks for frontend development. Django and Express are backend frameworks. Django for python, Express for javascript. Django is sort of a batteries included framework in the sense that it comes by default with many things you might need, like an authentication system, an ORM (which is a way to make it easier for your code to interact with a database) and a pretty good admin page where you can do things like see, add, change, delete objects in the database, among other things. A framework, btw, is sort of a way to do things that comes with code already written for things you're likely to use, so you don't have to do everything yourself. For example, if I don't use something like django, I'd have to write all the code myself to handle routing (what do the different paths in your applicagion do), handle users, authentication, security, and a thousand other things. So frameworks help yo save time. Not all frameworks are as batteries included as Django, Express, for example, is a lot more barebones. An API is how two programs communicate with each other. In cases where the backend and the frontend are separate (which doesn't need to be the case, you could just generate all your html from the backend), the way it usually works is that the backend exposes an API to the frontend, which the frontend then uses to get the data it needs to render a page.

I get that HTML, CSS, and Javascript are front-end languages, but how do we connect the back-end and front-end? Your backend will be a server your frontend communicates with via an API. In short, what are they? Are they libraries? Programs? How do they compare to Shiny? How do they relate to each other? Thanks! Those are all different technologies and not all of them overlap. Some are runtimes, some frontend frameworks, some libraries. It might be more helpful to Google each one and ask a more specific question for what you need help understanding. Bonus questions: PHP vs. HTML/CSS/JS, and what is an API PHP is a server-side (backend) scripting language, where as HTML/CSS/JS make up the core frontend languages. An API is an abstraction that allows for standardized communication between software components. For a real world analogy think of your stovetop. You have a knob that lets you turn it off/on/adjust temperature. You have no idea how the internals work, but you’re provided an interface (the knob) that allows you to communicate with the stove.

The server runs on port 3000.
