Node.js parent path from server.js - node.js

My is there c:\nodejs\www\project\bin\server.js
My views are in c:\nodejs\www\project\views
Then in my server.js I have:
.set('views', __dirname + '/views')
But the generated path is: c:\nodejs\www\project\bin\views
How to get the parent of bin folder?
I use Express and Ejs.
Regards

there are two ways of doing this, I can think :
.set('views',__dirname + '../views');
Or
you can use path.join from the path module
var path = require("path"),
.set(path.join(__dirname, '..', 'views'));
these will get your back one parent in the directory structure to find the file.

How to serve bower_components in Node.js using feathersjs?

I try serve bower_components directory who's a location is in root path to include jQuery and Bootstrap frameworks. Node has default serve a public directory. Below is my snippet code, but is not working. I have correctly installed bootstrap framework and jQuery. I used a bower. What I do wrong?
app.use('/', feathers.static(app.get('public')))
.use('jquery', feathers.static(__dirname + '../../bower_components'))
.use('bootstrap', feathers.static(__dirname + '../../bower_components'));
If you want to do it this way you have to link to the actual folder within bower_components:
const path = require('path');
const bowerComponents = path.join(__dirname, '..', '..', 'bower_components');
app.use('/', feathers.static(app.get('public')))
.use('/jquery', feathers.static(path.join(bowerComponents, 'jquery'))
.use('/bootstrap', feathers.static(path.join(bowerComponents, 'bootstrap')));

Node.js: Path issues for EJS page templates

Using a MEAN environment (Express 4) and EJS as a template engine, I am struggling with a path issue.
Root path of my project: /Users/admin/projectX/
path of pages (.ejs format): /Users/admin/projectX/views/pages
path of partials(.ejs format): /Users/admin/projectX/views/partials
Code samples:
app.set('view engine', 'ejs'); //using ejs as template engine instead of jade
app.set('views', __dirname + '/views'); //defining absolute path of views folder
//sample route for calling index.ejs
app.route('/')
.get(function(req, res) {
res.render('/pages/index'); //index.ejs is located in the pages folder (full path see list above)
});
For some reason I keep getting this error:
Error: Failed to lookup view "/pages/index" in views directory "/Users/admin/projectX/views"
IMHO the path should correctly add up to /Users/admin/projectX/views/pages/index, so why can't it be found?!

how to set and use partials view paths in node.js + expressJS

I am having problems in setting partial view paths in nodeJs + expressJs. Below is my directory structure.
Directory Structure
packages
--Module1
----Views
------sample.ejs
--sharedModule
----Views
------partials
--------Module1.ejs
--------partialHTML.ejs //able to use in index.ejs
------index.ejs //Used : <% include partials/partialHTML%>
ExpressJS:
var express = require('express');
var app = express();
app.set('view engine', 'ejs');
app.set('views', path.join(__dirname, 'packages/sharedModule/views'));
I am able to use 'partialHTML.ejs' in index.ejs file using <% include partials/partialHTML%>..
How can i use Module1.ejs files under Module1/view/sample.ejs file ?
You've set packages/sharedModule/views as your views directory, sample.ejs is no where under that dir, it's under another path. That's why it's not found.
In Linux you could create a soft link to point the shared views Module1/views/sharedviews ==> ../../sharedModule/views, then set your Module1 as the root path for views -
app.set('views', path.join(__dirname, 'packages/Module1/views'));
So when you look for any view, it's guaranteed to be found, since now your views dir has both Module1 and sharedModule views.

how to set path to the views (template) directory and to static files in node.js

I have created layout.jade, navigation.jade, and index.jade, and I want to glue them together.
In server.js, how do I
set the path to the views (template) directory, and
set the path to static files.
Is it required that node_module be placed in the folder that contains server.js?
Below is the code for server.js:
//create an app server
var express = require("express");
var server = express.createServer();
//set path to the views (template) directory
app.set('views', D:\#Programming\node.js\trial box\views);
//set path to static files
//how is the path to static files set?
app.use(express.static(__dirname + '/../public'));
//handle GET requests on /
app.get('/', function(req, res){
res.render('index.jade', {title: 'web project'});
});
//listen on localhost:3000
app.listen(3000);
Thank you in advance.
This questions a little old, but I'll still leave an answer. You'll need to place your app.use(... statement inside a callback function for app.configure() like so..
app.configure(function(){
app.use(express.static(__dirname + '/../public'));
});
You should use the express bin tool to bootstrap a project you'd get all that setup.
To install it:
sudo npm install express -g

Express-js can't GET my static files, why?

I've reduced my code to the simplest express-js app I could make:
var express = require("express"),
app = express.createServer();
app.use(express.static(__dirname + '/styles'));
app.listen(3001);
My directory look like this:
static_file.js
/styles
default.css
Yet when I access http://localhost:3001/styles/default.css I get the following error:
Cannot GET / styles /
default.css
I'm using express 2.3.3 and node 0.4.7. What am I doing wrong?
Try http://localhost:3001/default.css.
To have /styles in your request URL, use:
app.use("/styles", express.static(__dirname + '/styles'));
Look at the examples on this page:
//Serve static content for the app from the "public" directory in the application directory.
// GET /style.css etc
app.use(express.static(__dirname + '/public'));
// Mount the middleware at "/static" to serve static content only when their request path is prefixed with "/static".
// GET /static/style.css etc.
app.use('/static', express.static(__dirname + '/public'));
I have the same problem. I have resolved the problem with following code:
app.use('/img',express.static(path.join(__dirname, 'public/images')));
app.use('/js',express.static(path.join(__dirname, 'public/javascripts')));
app.use('/css',express.static(path.join(__dirname, 'public/stylesheets')));
Static request example:
http://pruebaexpress.lite.c9.io/js/socket.io.js
I need a more simple solution. Does it exist?
This work for me:
app.use('*/css',express.static('public/css'));
app.use('*/js',express.static('public/js'));
app.use('*/images',express.static('public/images'));
default.css should be available at http://localhost:3001/default.css
The styles in app.use(express.static(__dirname + '/styles')); just tells express to look in the styles directory for a static file to serve. It doesn't (confusingly) then form part of the path it is available on.
In your server.js :
var express = require("express");
var app = express();
app.use(express.static(__dirname + '/public'));
You have declared express and app separately, create a folder named 'public' or as you like, and yet you can access to these folder. In your template src, you have added the relative path from /public (or the name of your folder destiny to static files). Beware of the bars on the routes.
I am using Bootstrap CSS, JS and Fonts in my application. I created a folder called asset in root directory of the app and place all these folder inside it. Then in server file added following line:
app.use("/asset",express.static("asset"));
This line enables me to load the files that are in the asset directory from the /asset path prefix like: http://localhost:3000/asset/css/bootstrap.min.css.
Now in the views I can simply include CSS and JS like below:
<link href="/asset/css/bootstrap.min.css" rel="stylesheet">
What worked for me is:
Instead of writing app.use(express.static(__dirname + 'public/images')); in your app.js
Simply write
app.use(express.static('public/images'));
i.e remove the root directory name in the path. And then you can use the static path effectively in other js files, For example:
<img src="/images/misc/background.jpg">
Hope this helps :)
to serve static files (css,images,js files)just two steps:
pass the directory of css files to built in middleware express.static
var express = require('express');
var app = express();
/*public is folder in my project directory contains three folders
css,image,js
*/
//css =>folder contains css file
//image=>folder contains images
//js =>folder contains javascript files
app.use(express.static( 'public/css'));
to access css files or images just type in url http://localhost:port/filename.css ex:http://localhost:8081/bootstrap.css
note: to link css files to html just type<link href="file_name.css" rel="stylesheet">
if i write this code
var express = require('express');
var app = express();
app.use('/css',express.static( 'public/css'));
to access the static files just type in url:localhost:port/css/filename.css
ex:http://localhost:8081/css/bootstrap.css
note to link css files with html just add the following line
<link href="css/file_name.css" rel="stylesheet">
this one worked for me
app.use(express.static(path.join(__dirname, 'public')));
app.use('/img',express.static(path.join(__dirname, 'public/images')));
app.use('/shopping-cart/javascripts',express.static(path.join(__dirname, 'public/javascripts')));
app.use('/shopping-cart/stylesheets',express.static(path.join(__dirname, 'public/stylesheets')));
app.use('/user/stylesheets',express.static(path.join(__dirname, 'public/stylesheets')));
app.use('/user/javascripts',express.static(path.join(__dirname, 'public/javascripts')));
Webpack makes things awkward
As a supplement to all the other already existing solutions:
First things first: If you base the paths of your files and directories on the cwd (current working directory), things should work as usual, as the cwd is the folder where you were when you started node (or npm start, yarn run etc).
However...
If you are using webpack, __dirname behavior will be very different, depending on your node.__dirname settings, and your webpack version:
In Webpack v4, the default behavior for __dirname is just /, as documented here.
In this case, you usually want to add this to your config which makes it act like the default in v5, that is __filename and __dirname now behave as-is but for the output file:
module.exports = {
// ...
node: {
// generate actual output file information
// see: https://webpack.js.org/configuration/node/#node__filename
__dirname: false,
__filename: false,
}
};
This has also been discussed here.
In Webpack v5, per the documentation here, the default is already for __filename and __dirname to behave as-is but for the output file, thereby achieving the same result as the config change for v4.
Example
For example, let's say:
you want to add the static public folder
it is located next to your output (usually dist) folder, and you have no sub-folders in dist, it's probably going to look like this
const ServerRoot = path.resolve(__dirname /** dist */, '..');
// ...
app.use(express.static(path.join(ServerRoot, 'public'))
(important: again, this is independent of where your source file is, only looks at where your output files are!)
More advanced Webpack scenarios
Things get more complicated if you have multiple entry points in different output directories, as the __dirname for the same file might be different for output file (that is each file in entry), depending on the location of the output file that this source file was merged into, and what's worse, the same source file might be merged into multiple different output files.
You probably want to avoid this kind of scenario scenario, or, if you cannot avoid it, use Webpack to manage and infuse the correct paths for you, possibly via the DefinePlugin or the EnvironmentPlugin.
The problem with serving __dirname is that __dirname returns the path of the current file, not the project's file.
Also, if you use a dynamic header, each page will look for the static files in a different path and it won't work.
The best, for me, is to substitute __dirname for process.cwd() which ALWAYS donates the path to the project file.
app.use(express.static(process.cwd() + '/public'));
And in your project:
link rel="stylesheet" href="/styles/default.css"
See: What's the difference between process.cwd() vs __dirname?
I was using
app.use(express.static('public'))
When there was no file in the public folder with name index.html.
I was getting the following error in the browser:
"Cannot GET /"
When I renamed the file to 'index.html', it works fine.
Try accessing it with http://localhost:3001/default.css.
app.use(express.static(__dirname + '/styles'));
You are actually giving it the name of folder i.e. styles not your suburl.
I find my css file and add a route to it:
app.get('/css/MyCSS.css', function(req, res){
res.sendFile(__dirname + '/public/css/MyCSS.css');
});
Then it seems to work.
if your setup
myApp
|
|__ public
| |
| |__ stylesheets
| | |
| | |__ style.css
| |
| |___ img
| |
| |__ logo.png
|
|__ app.js
then,
put in app.js
app.use('/static', express.static('public'));
and refer to your style.css: (in some .pug file):
link(rel='stylesheet', href='/static/stylesheets/style.css')
Try './public' instead of __dirname + '/public'.
Similarly, try process.cwd() + '/public'.
Sometimes we lose track of the directories we are working with, its good to avoid assuming that files are located where we are telling express where they are.
Similarly, avoid assuming that in the depths of dependencies the path is being interpreted the same way at every level.
app.use(express.static(__dirname+'/'));
This worked for me, I tried using a public directory but it didn't work.
But in this case, we give access to the whole static files in the directory, hope it helps!
In addition to above, make sure the static file path begins with / (ex... /assets/css)... to serve static files in any directory above the main directory (/main)
Create a folder with 'public' name in Nodejs project
folder.
Put index.html file into of Nodejs project folder.
Put all script and css file into public
folder.
Use app.use( express.static('public'));
and in index.html correct path of scripts to <script type="text/javascript" src="/javasrc/example.js"></script>
And Now all things work fine.
static directory
check the above image(static directory) for dir structure
const publicDirectoryPath = path.join(__dirname,'../public')
app.use(express.static(publicDirectoryPath))
// or
app.use("/", express.static(publicDirectoryPath))
app.use((req, res, next) => {
res.sendFile(path.join(publicDirectoryPath,'index.html'))
In your nodejs file
const express = require('express');
const app = express();
app.use('/static', express.static('path_to_static_folder'));
In your pug file
...
script(type="text/javascript", src="static/your_javascript_filename")
...
Note the "static" word. It must be same in nodejs file and pug file.
i just try this code and working
const exp = require('express');
const app = exp();
app.use(exp.static("public"));
and working,
before (not working) :
const express = require('express');
const app = express();
app.use(express.static("public"));
just try
