I got SyntaxError: expected expression, got '<' error in the console when i’m executing following node code
var express = require('express');
var app = express();
app.all('*', function (req, res) {
res.sendFile(__dirname+'/index.html') /* <= Where my ng-view is located */
})
var server = app.listen(3000, function () {
var host = server.address().address
var port = server.address().port
})
Error :
I’m using Angular Js and it’s folder structure like bellow
What’s I’m missing here ?

This code:
app.all('*', function (req, res) {
res.sendFile(__dirname+'/index.html') /* <= Where my ng-view is located */
})
tells Express that no matter what the browser requests, your server should return index.html. So when the browser requests JavaScript files like jquery-x.y.z.main.js or angular.min.js, your server is returning the contents of index.html, which start with <!DOCTYPE html>, which causes the JavaScript error.
Your code inside the callback should be looking at the request to determine which file to send back, and/or you should be using a different path pattern with app.all. See the routing guide for details.

Try this, usually works for me:
app.set('appPath', 'public');
app.use(express.static(__dirname +'/public'));
app.route('/*')
.get(function(req, res) {
res.sendfile(app.get('appPath') + '/index.html');
});
Where the directory public contains my index.html and references all my angular files in the folder bower_components.
The express.static portion I believe serves the static files correctly (.js and css files as referenced by your index.html). Judging by your code, you will probably need to use this line instead:
app.use(express.static(__dirname));
as it seems all your JS files, index.html and your JS server file are in the same directory.
I think what @T.J. Crowder was trying to say was use app.route to send different files other than index.html, as just using index.html will have your program just look for .html files and cause the JS error.
Hope this works!

The main idea is that somehow HTML has been returned instead of Javascript.
The reason may be:
- wrong paths
- assets itself
It may be caused by wrong assets precompilation. In my case, I caught this error because of wrong encoding.
When I opened my application.js I saw
application error Encoding::UndefinedConversionError at /assets/application.js
There was full backtrace of error formatted as HTML instead of Javasript.
Make sure that assets had been successfully precompiled.

I had same error. And in my case
REASON: There was restriction to that resources on server and server was sending login page instead of javascript pages.
SOLUTION: give access to user for resourses or remove restriction at all.

You can also get this error message when you place an inline tag in your html but make the (common for me) typo that you forget to add the slash to the closing-script tag like this:
<script>
alert("I ran!");
<script> <!-- OOPS opened script tag again instead of closing it -->
The JS interpreter tries to «execute» the tag, which looks like an expression beginning with a less-than sign, hence the error: SyntaxError: expected expression, got '<'

Just simply add:
app.use(express.static(__dirname +'/app'));
where '/app' is the directory where your index.html resides or your Webapp.

I had this same error when I migrated a WordPress site to another server.
The URL in the header for my js scripts was still pointing to the old server and domain name.
Once I updated the domain name, the error went away.
answered Mar 20, 2015 at 21:11
I had a similar problem using Angular js. i had a rewrite all to index.html in my .htaccess.
The solution was to add the correct path slashes in .
Each situation is unique, but hope this helps someone.

This problem occurs when your are including file with wrong path and server gives some 404 error in loading file.

This should work for you. If you are using SPA.
app.use('/', express.static(path.join(__dirname, 'your folder')));
// Send all other requests to the SPA
app.get('*', (req, res) => {
res.sendFile(path.join(__dirname, 'your folder/index.html'));
});

I was getting this error when trying to access an angular SPA via ASP.NET Core. Turns out the environment variables were not being loaded correctly, and the following line was not being called:
app.UseSpaStaticFiles();
After I ensured the line was getting called, the app started working again.

I got this type question on Django, and My issue is forget to add static to the <script> tag.
Such as in my template:
<script type="text/javascript" src="css/layer.js"></script>
I should add the static to it like this:
<script type="text/javascript" src="{% static 'css/layer.js' %}" ></script>

May be this helps someone. The error I was getting was
SyntaxError: expected expression, got ‘<‘
What I did clicked on view source in chrome and there I found this error
Notice: Undefined variable: string in
D:Projectsdemoge.php on line 66
The issue was this snippet of code,
$string= ''; <---- this should be declared outside the loop
while($row = mysql_fetch_assoc($result))
{
$string .= '{ id:'.$row['menu_id'].', pId:'.$row['parent_id'].', name:"'.$row['menu_name'].'"},';
}
which fixed the problem.

The JavaScript exceptions «unexpected token» occur when a specific language construct
was expected, but something else was provided. This might be a simple typo.
Message
SyntaxError: expected expression, got "x" SyntaxError: expected property name, got "x" SyntaxError: expected target, got "x" SyntaxError: expected rest argument name, got "x" SyntaxError: expected closing parenthesis, got "x" SyntaxError: expected '=>' after argument list, got "x"
Error type
What went wrong?
A specific language construct was expected, but something else was provided. This might
be a simple typo.
Examples
Expression expected
For example, when chaining expressions, trailing commas are not allowed.
for (let i = 0; i < 5,; ++i) {
console.log(i);
}
// Uncaught SyntaxError: expected expression, got ';'
Correct would be omitting the comma or adding another expression:
for (let i = 0; i < 5; ++i) {
console.log(i);
}
Not enough brackets
Sometimes, you leave out brackets around if statements:
function round(n, upperBound, lowerBound) {
if (n > upperBound) || (n < lowerBound) { // Not enough brackets here!
throw new Error(`Number ${n} is more than ${upperBound} or less than ${lowerBound}`);
} else if (n < (upperBound + lowerBound) / 2) {
return lowerBound;
} else {
return upperBound;
}
} // SyntaxError: expected expression, got '||'
The brackets may look correct at first, but note how the || is outside the
brackets. Correct would be putting brackets around the ||:
function round(n, upperBound, lowerBound) {
if ((n > upperBound) || (n < lowerBound)) {
throw new Error(`Number ${n} is more than ${upperBound} or less than ${lowerBound}`);
} else if (n < (upperBound + lowerBound) / 2) {
return lowerBound;
} else {
return upperBound;
}
}

Have been dealing with the evil SyntaxError: expected expression, got '<' on Firefox in the last couple of days and had totally no idea what had been gone wrong. Everything worked fine and great on Chrome 55, Opera 41, Safari 10 but not FF 50+.
***Update: This error SyntaxError: expected expression, got '<' is most likely to happen when Service Workers is enabled and working fine on the browser. Since Service Worker in SPA will re-route basically anything that is not found to /index.html (according to default configuration) and so it does the same for .js. That’s why when app-indexeddb-mirror is looking for its .js files Service Worker couldn’t find it and just routed it to /index.html which then caused SyntaxError. In order to resolve that, we have to deliberately tell Service Worker to cache all the .js files within app-indexeddb-mirror like the following:
// sw-precache-config.js
module.exports = {
staticFileGlobs: [
'/index.html',
'/manifest.json',
'/bower_components/webcomponentsjs/webcomponents-lite.min.js',
'/bower_components/app-storage/app-indexeddb-mirror/app-indexeddb-mirror-worker.js', // Ask sw to cache `app-indexeddb-mirror`'s .js files
'/bower_components/app-storage/app-indexeddb-mirror/common-worker-scope.js' // Ask sw to cache `app-indexeddb-mirror`'s .js files
],
navigateFallback: '/index.html',
navigateFallbackWhitelist: [ /^/[^_]+/?/ ] // Firebase Auth's exception route.
};
***Additional step for Firefox: Head over to about:debugging#workers in Firefox and unregister all service workers. Clear your offline storage in FF. Do a page refresh and boom!!! Everything works as expected without throwing SyntaxError anymore. Hope this will help those struggling with the evil SyntaxError. 😄
app-indexeddb-mirror caches all JSONs from Firebase for offline use on all modern browsers.
FF50+ suffers from SyntaxError: expected expression, got '<'.

Начну с того, что данный код был сгенерен в gii и как бы оно работало и без всего этого. На сколько я понял по ответам, проблема заключается в том, что на запрос валидации возвращается html код вместо json.
Признаюсь я еще не полностью освоил фреймворк но все же, я написал для того чтобы получить ясность в этой неловкой ситуации.

Начну с того, что данный код был сгенерен в gii и как бы оно работало и без всего этого. На сколько я понял по ответам, проблема заключается в том, что на запрос валидации возвращается html код вместо json.
Признаюсь я еще не полностью освоил фреймворк но все же, я написал для того чтобы получить ясность в этой неловкой ситуации.
как оно могло работать, если оно не включено? у вас работала обычная клиентская валидация. А ошибка вообще не связана с темой.
