Link css in index.html, ReferenceError: window not defined #625

cpunion · 2016-09-11T13:04:34Z

I used pace.js to got a better loading experience, but it can't be linked in index.html, some errors raised:

Pace.js must be loaded quickly, shouldn't require it in project's code.

CRA 0.4.1 doesn't support serving local static assets like you did in index.html. See Related: version 0.4.1 serves non-HTML files as text/html #573 Disable implicit serving of the source files #551. So remove the links (css and js) from your index.html.
pace-js relies on pace. Unfortunately the pace-js doesn't attempt to require pace although both are on npm. Note this is also very confusing due to the unfortunately very similar package names. So in your package.json you need to add "pace": "^0.0.4" explicitly.
And, add the following in your index.js:

import 'pace-js/themes/blue/pace-theme-minimal.css';
import 'pace-js';

fson · 2016-09-11T17:44:36Z

@cloudmu is right, the right way to include it would be importing in index.js However, it seems that even though pace-js is published on npm, it can't currently be loaded as a module (which is a bummer). The reason is that it has an invalid AMD define in its source, which defines pace as a dependency (pace on npm is an unrelated command line tool, not actually used by pace-js). So while installing pace seems to fix the problem, it also pulls in some code from a package that is not used.

The best solution would be to fix Pace so that it can be imported normally without depending on a different pace package. There's an issue in the Pace repo: CodeByZach/pace#328

Another workaround would be to use it from a CDN, which you can add to index.html:

    <link href="https://unpkg.com/pace-js/themes/blue/pace-theme-minimal.css" rel="stylesheet" />
    <script src="https://unpkg.com/pace-js@1.0.2/pace.min.js"></script>

However, it's possible and likely that your app loads faster with the method described above (import) because then the script and styles can be bundled with your app's code and loaded with a single roundtrip to the server.

gaearon · 2016-09-11T17:46:40Z

I think the author wants to avoid imports and bundling intentionally because the sole reason pace exists is to show a progress bar while the rest of the content is loading.

gaearon · 2016-09-11T17:47:22Z

I'd like to keep this open because this is one of use cases we should make sure we have a reasonable way of supporting before 1.0.

cloudmu · 2016-09-11T17:54:38Z

@fson thanks for pointing out pace is an unintended dependency (bug in pace-js).

cpunion · 2016-09-12T02:40:57Z

Thanks @cloudmu, @fson . I will temporarily link it from CDN.

@gaearon thanks for adding to 1.0.0 milestone.

bestwestern · 2016-09-14T11:15:18Z

I would very much hate to lose this!
'CRA 0.4.1 doesn't support serving local static assets like you did in index.html. '
(I will be forced to use older version - I am using webpack without cssloader in a parent folder to do builds to a wwwroot folder.. I am not very good with webpack so the create-react-app is great but I need to be able serve local statis assets)
How would I make it possible after an eject?
Serving a lot of static files would make development with create-react-app very slow?

gaearon · 2016-09-22T19:16:11Z

I drafted a proposal to solve this in #703. Unless we find some fatal flaws, it should come out in 0.5.0. Let me know what you think!

cpunion · 2016-09-22T22:57:53Z

@gaearon Great!

gaearon · 2016-09-22T23:37:42Z

Closing as this is fixed, and will be released in 0.5.0.

bestwestern · 2016-09-23T10:59:10Z

It looks great - can't wait to try it out.
Thank you.

gaearon · 2016-09-23T21:56:17Z

This is now supported in 0.5.0.

Read about using the new public folder.

See also migration instructions and breaking changes in 0.5.0.

cpunion · 2016-09-23T22:53:37Z

@gaearon Thanks for release 0.5.0 so quickly. I migrated to 0.5.0, but found a problem.

Content in my index.html:

  <link href="%PUBLIC_URL%/pace/theme/pace-theme-minimal.css" rel="stylesheet" />
  <script type="text/javascript">
    paceOptions = {ajax: {trackWebSockets: false}};
  </script>
  <script src="%PUBLIC_URL%/pace/pace.js"></script>

It be converted to:

  <link href="/pace/theme/pace-theme-minimal.css" rel="stylesheet" />
  <script type="text/javascript">
    paceOptions = {ajax: {trackWebSockets: false}};
  </script>
  <script src="%PUBLIC_URL%/pace/pace.js"></script>

Seems it just replaces the first %PUBLIC_URL%?

Below is my public folder:

├── index.html
└── pace
    ├── pace.js
    └── theme
        ├── pace-theme-center-atom.css
        └── pace-theme-minimal.css

Errors in terminal:

gaearon · 2016-09-23T23:06:47Z

Oops, that might be true. Blame this on me not knowing how replace() works in JS :-P. Would you like to send a fix? It's in InterpolateHtmlPlugin.js in packages/react-dev-utils.

fson · 2016-09-23T23:07:12Z

I'm already fixing this :)

@fson 👍

Fixes #625 (comment).

gaearon · 2016-09-23T23:28:53Z

Fixed by #731.
0.5.1 will be out shortly.

gaearon · 2016-09-24T00:08:14Z

0.5.1 is out, I just verified this is fixed in it.
https://github.com/facebookincubator/create-react-app/releases/tag/v0.5.1

cpunion · 2016-09-24T00:25:48Z

Fixed, thanks.

A little problem, I migrated from 0.5.0 to 0.5.1 with below command:

$ npm install --save-dev --save-exact react-scripts@0.5.1
myproject@0.1.0 /Users/lijie/myproject
└── react-scripts@0.5.1

But the version of react-dev-utils in node_modules/react-scripts/node_modules not upgraded, I MUST delete node_modules and then npm i.

gaearon · 2016-09-24T00:44:01Z

That's weird. I guess not a big deal if new projects reference the correct version (I doubt a lot of people had a chance to catch 0.5.0 before 0.5.1 came out.) Will keep this in mind for the future.
