I tried to wire up a code from: https://github.com/wimagguc/nodejs-static-http-with-gzip/blob/master/http-with-gzip.js Directories and Server.js File I made changes by adding the code:
path.exists(filePath, function(exists) {
if (exists) {
fs.readFile(filePath, function(error, content) {
if (error) {
response.writeHead(500);
response.end();
}
else {
var raw = fs.createReadStream(filePath);
if (acceptEncoding.match(/\bdeflate\b/)) {
response.writeHead(200, { 'content-encoding': 'deflate' });
raw.pipe(zlib.createDeflate()).pipe(response);
} else if (acceptEncoding.match(/\bgzip\b/)) {
response.writeHead(200, { 'content-encoding': 'gzip' });
raw.pipe(zlib.createGzip()).pipe(response);
} else {
response.writeHead(200, {});
raw.pipe(response);
}
}
});
}
else {
response.writeHead(404);
response.end();
}
in the server.js at:
app.get('/', (req, res) => {
//this place
res.render('home.hbs', {
pageTitle: 'Home Page',
welcomeMess: 'Welcome to my Site'
})
}); the error: path.exists is not a function. but i could not understand the same and broke my app.
i was hoping to get a file that is gzipped. I am using express for handling the server
The problem is the code you use relies on old node versions. path.exists
was replaced with fs.exists
. You code could be like this (with minimal changes)
var fs = require("fs");
//...
path.exists(filePath, function(exists) {
//...
}
Be aware that this method is deprecated and you should look for alternatives either use fs.stat or fs.access or even path-exists package if you don't mind external dependency. Anyway with fs.access
it would be like this
fs.access(filePath, (err) => {
if (err) {
response.writeHead(404);
response.end();
}else{
// ... rest of the method (here you know file exists and accessible)
}
});
The difference being the error is the first prameter in the callback.
