REST API JavaScript Reddit - search subreddit

I am trying to create a web page where the user can type in a subreddit name and then the webpage returns data based on that webpage like the posts, or the name of the moderators etc..
I want to create a REST api in nodejs/express.
i have done a bit of research and i think i have to get the json data from the subreddit i want and then get the relevant data...
The part i am confused is how do i start? everything i see is got to do with python but i need to do it in nodejs.
Also wont the json keep changing format... for one subreddit it will be different to another subreddit

I feel like you should check if theres an API for Reddit. Then when the user types in a subreddit, you would issue a GET request from your express route. The GET request would get the information from the Reddit API and send it back to the front.
let express = require('express');
let app = express();
app.get('/api/subredditname', (req, res) => {
//make your api request here, returning a promise hopefully
//then send your data back
.then((data) => {
res.send(data).status(200);
})
.catch((err) => {
console.log(err);
});
};

How to get all reviews in themoviedb api?

I am creating a rest api , I would like to retrieve or get all reviews/comments which are in a database.
This is what I have done :
app.get('/review', (req, res) =>{
request('https://api.themoviedb.org/3/review?api_key=4d9c9de3bdf0d3b6837c49c086e3b190', function (error, response, body) {
console.log('error:', error); // Print the error if one occurred and handle it
console.log('statusCode:', response && response.statusCode); // Print the response status code if a response was received
res.send(body)
});
});
I am getting this error:
{"status_code":34,"status_message":"The resource you requested could not be found."}
what am I doing wrong here? help
Note: other methods works perfectly

This isn't a JS error or anything. If you look at the API Documentation, status_code: 34 means you're accessing an endpoint that doesn't exist.
Diving into the docs a bit further, you can't get ALL the reviews in the database. All you can do is get the reviews on a per movie basis. Try this URL:
https://api.themoviedb.org/3/movie/401478/reviews?api_key=4d9c9de3bdf0d3b6837c49c086e3b190
Here's the documentation on the /movie/<movie_id>/reviews endpoint: https://developers.themoviedb.org/3/movies/get-movie-reviews
There is also the /review/<review_id> end point, but it appears that gets a single review by id which probably isn't what you're looking for:
https://developers.themoviedb.org/3/reviews/get-review-details

It has nothing to do with nodeJS.As stated by #VicJordan, the problem is only with the url you are trying to search, it's simply not a valid API request. Try to go thru API documentation to find out how to use them. An example of a valid URL would be:
https://api.themoviedb.org/3/discover/movie?api_key=4d9c9de3bdf0d3b6837c49c086e3b190

How to make api requests to sabre / travel api (node js app)?

I am using the travel api from sabre and cannot make any http requests to any endpoint but 1. I don't understand what I am doing wrong. Im also not sure if I need a token since its just a test developer account and as I understand,I wouldn't need to require token?! if anyone has some experience with the saber api or api requests (maybe my code is wrong for other reasons) any help would be super much appreciated!! Thanks!!
Ps. I am using nodejs.
Api code that works:
var router = require('express').Router();
var SabreDevStudio = require('sabre-dev-studio');
var sabre_dev_studio = new SabreDevStudio({
client_id: 'V1:xxx',
client_secret: 'xxx',
uri: 'https://api.test.sabre.com'
});
var options = {};
router.get('/allcities', function (req, res) {
sabre_dev_studio.get('/v1/lists/supported/shop/themes', options, function (err, data) {
if (err) {
res.status(200).send(err);
} else {
res.status(200).send(data);
}
});
});
Api call (below) to get the lowest fares of picked destination doesn't work. In sabre's documentation I find this:
GET https://api.havail.sabre.com/v1/shop/flights/cheapest/fares/DFW HTTP/1.1
documentation: https://developer.sabre.com/docs/rest_apis/air/search/flights_to/
router.get('/lowestFare', function(req,res){
sabre_dev_studio.get('/v1/shop/flights/cheapest/fares/DFW HTTP/1.1', options, function(err, data){
if (err){
res.status(200).send(err);
}
else{
res.status(200).send(data);
}
})
})
What am I doing wrong?
Thanks!

In order to send requests to SOAP or HTTP sabre API's you need to have spoken to a Sabre account manager and/or signed a contract with Sabre. They will inform you which environments you have access and to which Sabre APIs you have access.
I presume you are only interested in the REST API's, namely the HTTP REST API 'Bargain Finder Max (BFM)', which is sabre's best-in-class low fare search product, used to search for the lowest available priced itineraries based upon a specific date. The 'Bargain Finder Max (BFM)' requires activation, documentation advises you to contact your Sabre Account Representative for assistance.
Firstly click here to obtain API key for test purposes. Register an account.
Obtain your personal 'key' and 'shared secret' after registration.
Click here for the test environment to get familiar with the REST API's.
The cheapest air search endpoint is part of the 'Air Search' HTTP REST API. This is an endpoint which supports HTTP GET requests to find the 20 lowest published fares available for a given destination (destination required; the destination parameter is a 3-letter IATA airport code or city code of the arrival airport e.g. LAX - Los Angeles). Also you submit a pointofsalecountry parameter which is just a 2-letter country code of the point of sale e.g. US.
Using the API explorer invoke a HTTP GET request to the following URI:
https://api.test.sabre.com/v1/shop/flights/cheapest/fares/LAX?pointofsalecountry=US
In terms of your Express.js JavaScript code, you've setup a middleware callback function for GET requests to '/lowestFare' which in turn seems to send a HTTP GET request to the following URL: '/v1/shop/flights/cheapest/fares/DFW HTTP/1.1' this is not a valid URL and doesn't seem to have any query string or request data / options sent with it.
See this GitHub repository with a complete examples for consuming sabre REST API's with Node.js. The readme file here also states: 'Please register at https://developer.sabre.com contact Sabre in order to obtain your own credentials.'

Hide an API key (in an environment variable perhaps?) when using Angular

I'm running a small Angular application with a Node/Express backend.
In one of my Angular factories (i.e. on the client side) I make a $http request to Github to return user info. However, a Github-generated key (which is meant to be kept secret) is required to do this.
I know I can't use process.env.XYZ on the client side. I'm wondering how I could keep this api key a secret? Do I have to make the request on the back end instead? If so, how do I transfer the returned Github data to the front end?
Sorry if this seems simplistic but I am a relative novice, so any clear responses with code examples would be much appreciated. Thank you

Unfortunately you have to proxy the request on your backend to keep the key secret. (I am assuming that you need some user data that is unavailable via an unauthenticated request like https://api.github.com/users/rsp?callback=foo because otherwise you wouldn't need to use API keys in the first place - but you didn't say specifically what you need to do so it is just my guess).
What you can do is something like this: In your backend you can add a new route for your frontend just for getting the info. It can do whatever you need - using or not any secret API keys, verify the request, process the response before returning to your client etc.
Example:
var app = require('express')();
app.get('/github-user/:user', function (req, res) {
getUser(req.params.user, function (err, data) {
if (err) res.json({error: "Some error"});
else res.json(data);
});
});
function getUser(user, callback) {
// a stub function that should do something more
if (!user) callback("Error");
else callback(null, {user:user, name:"The user "+user});
}
app.listen(3000, function () {
console.log('Listening on port 3000');
});
In this example you can get the user info at:
http://localhost:3000/github-user/abc
The function getUser should make an actual request to GitHub and before you call it you can change if that is really your frontend that is making the request e.g. by cheching the "Referer" header or other things, validate the input etc.
Now, if you only need a public info then you may be able to use a public JSON-P API like this - an example using jQuery to make things simple:
var user = prompt("User name:");
var req = $.getJSON('https://api.github.com/users/'+user);
req.then(function (data) {
console.log(data);
});

How to get LinkedIn API access token without a redirect

I'm trying to use LinkedIn's API to access Universities LinkedIn pages to periodically collect how many followers they have. This seems doable, but I cant seem to generate an access token without having some weird redirect URL that has to take you to a GUI login page!
I'm using node.js for this, specifically this package: https://www.npmjs.org/package/node-linkedin
I have a API key and secret, so all I need is a access token then I'll be set to actually start using their API routes.
var Linkedin = require('node-linkedin')('KEY', 'SECRET', 'callback');
var linkedin = Linkedin.init('my_access_token'); // need a token to initialise!
Any ideas?
Edit: Here's my code so far:
var Linkedin = require('node-linkedin')('KEY', 'SECRET', './oauth/linkedin/callback');
app.get('/oauth/linkedin', function(req, res) {
// This will ask for permisssions etc and redirect to callback url.
Linkedin.auth.authorize(res, ['r_basicprofile', 'r_fullprofile', 'r_emailaddress', 'r_network', 'r_contactinfo', 'rw_nus', 'rw_groups', 'w_messages']);
});
app.get('/oauth/linkedin/callback', function(req, res) {
Linkedin.auth.getAccessToken(res, req.query.code, function(err, results) {
if ( err )
return console.error(err);
/**
* Results have something like:
* {"expires_in":5184000,"access_token":". . . ."}
*/
console.log(results);
var linkedin = Linkedin.init(result);
return res.redirect('/');
});
});

What you are trying to do is an application-only authentication, it seems linkedIn has removed this option unlike facebook and twitter. As from now it is only possible to authenticate as a user.
If you really want to skip the redirect you could use something like PhantomJS which is a headerless browser. But i strongly recommend you not to do so as LinkedIn requires a user to authenticate in their license agreement. I don't know if it is legal but you could provide yourself an end-point which you use to generate the authentication_code and access_token and then save it to a database (60 days valid by default).
