I am looking for a little help with trying to execute an http.get() request and update a variable based on the results. Then use that variable as a response to a request for a web page. I understand that node.js is asynchronous so it won't necessarily wait for one function to finish executing before completing another.
What I am essentially trying to accomplish is to simulate getting blog posts from an API via a get request. The get request responds with the posts in JSON format. Then I want to pass that variable to res.render(), which renders blog.ejs and iterates over the posts.
So, I am really just looking for the right technique to implement since the response is rendered before the http.get() request is finished.
app.get('/blog', function(req, res){
// Get blog posts from WordPress
var posts = {};
http.get({
hostname: 'localhost',
port: 3000,
path: '/',
agent: false
}, (res)=>{
posts = [{post:"Post 1"}];
});
res.render('blog', {
title: 'Blog',
posts: posts
})
}) //End /blog request
