I cannot for the life of me figure this out. The following site is hosted on Netlify and prerendering is enabled. When inspecting the page, all of the OG tags are correct. These tags are injected using react-helmet.
https://browniepoints.africa/opportunities/volunteer-at-a-soup-kitchen-every-week-on-thursdays
When scraping the above URL on the Facebook debugger, it responds with:
The following required properties are missing: og:url, og:type, og:title, og:image, og:description, fb:app_id
The only one of those errors/warnings that should be there is the app_id, which I don't care about.
I've waited well over 48 hours for caches to clear, I've tried scraping with query strings appended to the URL, and the images have absolute URLs. But not even the description tag is pulling through.
Can somebody that uses react-helmet and Netlify please shed some definitive light onto this problem?
This is related to a known prerendering issue.
My fix was to remove the <!DOCTYPE html> declaration from the index.html file as a temporary workaround until the above issue is resolved.
While I can't tell you exactly why. your SSR is not working correctly. Go to Chrome DevTools and click the 3 vertical dots next to Console:
Select Networking Conditions, then uncheck Select Automatically and enter Googlebot/2.1 (+http://www.google.com/bot.html):
Now refresh the page and notice that all you see on the site is some plaintext saying "html" and even your javascript bundle is missing. This is what your html looks like:
<html lang="en">
<head>
<meta charset="utf-8">
<meta name="fragment" content="!">
<link rel="shortcut icon" href="/favicon.ico">
<meta name="viewport" content="width=device-width,initial-scale=1,maximum-scale=1,user-scalable=no">
<title>Brownie Points</title>
<link href="/static/css/2.3bf0f3c5.chunk.css" rel="stylesheet">
</head>
<body><noscript>You need to enable JavaScript to run this app.</noscript>
<div id="root"></div>
</body>
</html>
Note that Netlify SSR is in Beta but I personally didn't have those issues with it. Have you done any other steps other than enable it? I have tested it to be working with a CRA generated app before.
I looked over some of the same questions on stack overflow and tried all the best answers. None of them worked.
I am learning html5 with CSS stylesheet. I looked over a website tutorial of building a web page with login form by flask.
So it has this base.html file which has some code links to a css file:
<head>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1">
<title>RELAX AND WORKOUT</title>
<link rel="stylesheet" href="bulma.css" />
</head>
Originally, followed by 'href' was a http link and it worked. But I downloaded the same css file and put it in the same folder as the base.html file so I can play with this css file.
They are both at ./project/templates/the_file
This is the link to download the css file: https://cdnjs.cloudflare.com/ajax/libs/bulma/0.7.4/css/bulma.css
It was also originally the tutorial author put after 'href='. But when I changed it to my local file name 'bulma.css', it does not load the stylesheet at all.
I also tried absolute path and relative path. Neither of them worked.
I'm running it on Windows 10. Using Python 3.7 and flask.
So in my case, how do I make the html load this local css file?
Edit:
Ok, I made it work eventually.
I made a new folder called "static" and put the css file inside it. Then I changed the path to this:
<link rel="stylesheet" href="../static/bulma.css" />.
Does it mean flask treats the "templates" folder as a special folder only for html templates, it does not recognize other file formats?
But I saw a question which the person put his css file in the same directory. The answer is to just add a dot and it worked. That was why I put it with all the other html templates in my templates folder. But it never worked in my case.
From flask docs:
Flask automatically adds a static view that takes a path relative to the flaskr/staticdirectory and serves it. The base.htmltemplate already has a link to the style.cssfile:
{{ url_for('static', filename='style.css') }}
You need to create a folder called static inside your flask app directory with your static files inside, ex.: CSS, images, etc.
In your html code use:
<head>
<link rel="stylesheet" href= {{ url_for('static', filename='bulma.css') }}>
</head>
Try changing your href="bulma.css" to href="./bulma.css" and see if it works.
Are you sure you don't have to go into the templates folder? "/templates/bulma.css"
Hit F12 to open up the development pane. Go to the network tab. Refresh the page. Is the file listed in that list? You may have to refresh your cache to have it take effect. To do that: CTRL+SHIFT+R. If the file is listed in there you can view the preview to make sure it's current, if not you will still need to do a force refresh on the cache.
As for URL's you can also use an absolute file path starting at the root with href="../project/templates/filename.css" (use 2 periods). The following is a website for more info on this:

Problem:
In my HTML file, I have:
<link href="https://fonts.googleapis.com/css?family=Roboto:300,400,500" rel="stylesheet">
I want the font to be available to users who can't access fonts.googleapis.com but can access my website.
Solution I went with:
I provide a locally-hosted alternative by following the steps here in google-webfonts.helper. To be specific:
I've created a file roboto.css under my /assets folder and pasted the code in step 3 in the link above.
Downloaded the fonts under /assets/fonts.
Added to index.html: <link href="/assets/roboto.css" rel="stylesheet">
To confirm: I still have the initial google fonts. I.e., my index.html has:
<link href="https://fonts.googleapis.com/css?family=Roboto:300,400,500" rel="stylesheet">
<link href="/assets/roboto.css" rel="stylesheet">
Question(s):
(1) Is double-importing that way harmful in anyway?
(2) Is what I'm doing right?
(3) Is there a better way to achieve what I want?
I am developing an Angular 4 app and I want to apply some global styles. Following the tutorial at the angular site, I've created a "styles.css" file in the root directory of my app, and I'm referring to that stylesheet in the index.html of my app:
<link rel="stylesheet" type="text/css" href="styles.css">
The angular app is successfully compiled:
$ ng serve
** NG Live Development Server is listening on localhost:4200, open your browser on http://localhost:4200 **
[...]
webpack: Compiled successfully.
But when I visit http://localhost:4200 in a Chromium browser, the console shows an error at
GET http://localhost:4200/styles.css
In a Firefox browser, the error is a bit more explicit:
GET
http://localhost:4200/styles.css [HTTP/1.1 404 Not Found 15ms]
The resource from "http://localhost:4200/styles.css" was blocked due to MIME type mismatch (X-Content-Type-Options: nosniff).
Both files, index.html and styles.css are located in the root directory of my angular app.
I've tried to get more info about the problem :
nosniff
Blocks a request if the requested type is
"style" and the MIME type is not "text/css", or
"script" and the MIME type is not a JavaScript MIME type.
But I don't understand why it's bloking the request, since I've specified type="text/css" when referencing the stylesheet.
I just ran into the same issue. It appears to be a quirk of Express that can manifest itself for a few different reasons, judging by the number of hits from searching the web for "nodejs express css mime type".
Despite the type="text/css" attribute we put in our <link elements, Express is returning the CSS file as
Content-Type: "text/html; charset=utf-8"
whereas it really should be returning it as
Content-Type: "text/css"
For me, the quick and dirty workaround was to simply remove the rel= attribute, i.e., change
<link rel="stylesheet" type="text/css" href="styles.css">
to
<link type="text/css" href="styles.css">
Testing confirmed that the CSS file was downloaded and the styles did actually work, and that was good enough for my purposes.
I also removed rel = "stylesheet", and I no longer get the MIME type error, but the styles are not being loaded
Some answers suggested removing rel="stylesheet", that didn't work out for me however.
According to the expressjs documentation: https://expressjs.com/en/starter/static-files.html
use express.static function to serve static files such as CSS, JavaScript,etc...
app.use(express.static('public'))
and from there you should be able to load any file under the public directory
for example, if you have a style.css file inside the directory {PROJECT_PATH}/public/css/
http://localhost:3000/css/style.css will work.
In running into the same kind of issue for a full stack web application (in development), I simply solved the problem by correctly linking the css file to the page rendered. Removing the rel = stylesheet, as suggested above, prevents the error to show up in the browser but it does not load the styles that should be applied to the page. In short, it isn't a solution.
If you are using express-static you can use this as an example:
Server-side:
app.use(express.static(__dirname + "/public", {
index: false,
immutable: true,
cacheControl: true,
maxAge: "30d"
}));
Client-side:
<link type="text/css" rel="stylesheet" href="/main.css">
Just add a forward slash in front of the file you wish to link to the html page (if you are rendering html pages without using any template engines) and express-static will do the rest automatically for you.
Had a similar problem with a javascript file (as opposed to css) in an Angular app. In reality, the problem wasn't with the Mime type (as the outer error message indicated) but was ultimately a "404 Not Found" error.
In my case, putting the script file anywhere but in the "assets" folder resulted in the 404 and eventually the mime type error. The following tag worked for me in the head section of index.html:
<script src="assets/plugins/jquery.min.js" type="text/javascript"></script>
The assets folder is a sibling of the Index.html file.
This is solved my problem:
app.use('/public', express.static(path.join(__dirname, "public")));
A simple hack is to add a forward slash / before the the path to the stylesheet used. For me it was href='css/style.css', changed it to href='/css/style.css'. Worked like a charm.
I also had this issue.
I moved the script file to a different location and now there is no error:
from <script src="./scripts/simple-keyboard/keyboard.index.min.js" type="text/html"></script>
to <script src="./scripts/keyboard.index.min.js" type="text/javascript"></script>
As noted by Davelli, the issue wasn't a file mismatch but an error not found. It's strange it returned the wrong error!
if this solutions does not help:
app.use(express.static('public'))//for server
<link rel="stylesheet" href="/index.css">//for styles
Then make sure that "public" folder exists in the root directory. This was my case.
I was facing the same problem. But I found out that it has to do with using the right directory for your style.css file. So I tried this line of code below and it worked perfectly.
<link rel="stylesheet" type="text/css" href="/app/scss/style.css">
In my case I just include "/" before "css/style.css"
<link rel="stylesheet" href="css/styles.css" />
to
<link rel="stylesheet" href="/css/styles.css" />
I also use express.static('public')
What seemed to work for me was changing
<script type="text/javascript" src="/lib/matrix.js"></script>
to
<script type="text/javascript" src="./lib/matrix.js"></script>
I ran into this problem as well. I was able to fix the problem with the tip from Kirankumar Gonti.
Use the following line:
app.use('/public', express.static(path.join(__dirname, "public")));
Make sure to set the const path.
You also want to make sure your css folder is nested inside a public folder.
I ran into this problem as well. I was able to fix the problem with the tip from Kirankumar Gonti.
I used the following line of code in my app.js file, I didn't have a public folder but had my style.css stored in a css folder:
app.use('/css', express.static(path.join(__dirname, "css")));
In my /css/style.css file I used:
<link rel="stylesheet" type="text/css" href="/css/style.css" />
For anyone still having this error I was able to solve it by including "src/assets" in my angular.json file
"assets": ["src/favicon.ico", "src/assets", "src/upload.php"]
also the directory of your index.html should not be included in the assets. meaning you should not include "src" in "assets"
In my case I had jumbled up the code blocks below in reverse order so I was getting this error. If you have this issue, follow the below order and it might help
1.
app.use(express.static(path.join(__dirname, 'public')));
2.
app.get('*', (req, res) => {
res.sendFile(path.join(__dirname, 'public/index.html'));
});
3.
app.use('/api', cors(corsOptions), indexRouter);
This is what happened at me,
My site was archieved, so the css and js files are not available. After restore my webhost everything goes well.
So, please check are the URLs is correct or not.
my question may not be related to react directly and maybe related to MVC routes only but i decided to share the bigger picture if anyone thinks i'm on the wrong track.
we have a React / redux application that bundles to an index.html file with css and js resources:
<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=device-width,initial-scale=1,maximum-scale=1,user-scalable=0" />
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta charset="utf-8" />
<title>Booking Engine</title>
<link href="./main.837f1985001f2e603b8755f0f28be780.css" rel="stylesheet">
</head>
<body>
<div id="sb-be"></div>
<script type="text/javascript" src="./main.adb11750acf05df99619.js"></script>
</body>
</html>
the resources are dynamicly hashed as you can see.
I need to serve this index.html from a MVC application, i tried to do that using this post (by using MapPageRoute and RouteExistingFiles in RouteConfig).
I can serve the html as expected, though the resources are not being served correctly.
This is my file structure in my MVC app:
--MVCRoot
----Other MVC related folders
----ReactFolder
--------dist
------------index.html
------------main[hash].js
------------main[hash].css
now using a MapPageRoute like so:
routes.MapPageRoute("index", "SomeName/{*pathInfo}", "~/ReactFolder/dist/index.html");
The resource files of main.js and main.css are being served as the index.html, i mean i literally get the index.html instead of the actual js and css files.
I tried with routes.RouteExistingFiles set to true or false but no help.
EDIT: basically my question is how to serve a html static file with a "pretty" (custom) URL without interrupting the page's resources load with their relative path?
