Additional context

[cascornelissen]

For some reason I can't seem to reproduce this but the stacktrace helped a lot. Can you verify the fix in c46f9eb resolves the issue for you?

You can install this from GitHub directly:

npm install cascornelissen/svg-spritemap-webpack-plugin#master

[xavierfoucrier]

Hi @cascornelissen,

I am working on upgrading my project and face the same issue.
Installing from your Github repo compiles fine, but there is no outputted SVG file.

I am using webpack@5.37.0 and webpack-dev-server@3.11.2.

Here is my webpack configuration for SVGSpritemapPlugin:

new SVGSpritemapPlugin('src/asset/vector/**/*.svg', {
  output: {
    filename: 'vector/sprite.svg',
    svgo: {
      floatPrecision: 2,
    },
  },
  sprite: {
    prefix: false,
    generate: {
      title: false,
    },
  },
}),

[cascornelissen]

If anyone can provide a repository that I can use to reproduce the issue, that'd help a lot. For some reason I can't seem to reproduce this on my system...

@xavierfoucrier, using your configuration with version 4 of this plugin throws a bunch of errors because the SVGO configuration isn't supported by SVGO 2, see release notes for additional information.

[xavierfoucrier]

@cascornelissen Yes I saw that the configuration changed, I will upgrade it and let you know.
By the way, using only SVGSpritemapPlugin() doesn't work too.

I will investigate and drop a minimal reproductible test repository if needed 😉

[xavierfoucrier]

@cascornelissen just to be sure, something like this works on your side?

output: {
  filename: 'vector/sprite.svg',
  svgo: {
    plugins: [{
      name: 'cleanupNumericValues',
      params: {
        floatPrecision: 2,
      },
    }],
  },
},

[cascornelissen]

Yes, that works on my side when using the latest commit of master as explained in #163 (comment). I replace the contents of examples/simple/webpack.config.js with this:

const SVGSpritemapPlugin = require('../..');

module.exports = {
    plugins: [
        new SVGSpritemapPlugin('src/**/*.svg', {
            output: {
                filename: 'vector/sprite.svg',
                svgo: {
                    plugins: [{
                        name: 'cleanupNumericValues',
                        params: {
                            floatPrecision: 2,
                        },
                    }],
                },
            },
        })
    ]
};

Then I do:

cd examples/simple/
rm -rf dist/
../../node_modules/.bin/webpack --mode production

Which succeeds with the following output:

asset vector/sprite.svg 680 bytes [compared for emit] [minimized]
asset main.js 0 bytes [compared for emit] [minimized] (name: main)
./src/index.js 41 bytes [built] [code generated]
spritemap-dummy-module 1 bytes [code generated]
webpack 5.37.0 compiled successfully in 160 ms

And a generated spritemap that seems to be correct:

<svg xmlns="http://www.w3.org/2000/svg"><symbol id="sprite-1" viewBox="0 0 24 24"><path d="M19 19H5V5h14m0-2H5a2 2 0 0 0-2 2v14a2 2 0 0 0 2 2h14a2 2 0 0 0 2-2V5a2 2 0 0 0-2-2m-7 14h2V7h-4v2h2"/></symbol><symbol id="sprite-2" viewBox="0 0 24 24"><path d="M15 15h-4v-2h2a2 2 0 0 0 2-2V9a2 2 0 0 0-2-2H9v2h4v2h-2a2 2 0 0 0-2 2v4h6m4 2H5V5h14m0-2H5a2 2 0 0 0-2 2v14a2 2 0 0 0 2 2h14a2 2 0 0 0 2-2V5a2 2 0 0 0-2-2z"/></symbol><symbol id="sprite-3" viewBox="0 0 24 24"><path d="M15 15v-1.5a1.5 1.5 0 0 0-1.5-1.5 1.5 1.5 0 0 0 1.5-1.5V9a2 2 0 0 0-2-2H9v2h4v2h-2v2h2v2H9v2h4a2 2 0 0 0 2-2m4 4H5V5h14m0-2H5a2 2 0 0 0-2 2v14a2 2 0 0 0 2 2h14a2 2 0 0 0 2-2V5a2 2 0 0 0-2-2z"/></symbol></svg>

[xavierfoucrier]

@cascornelissen on my side it compiles fine for production, so I guess the problem comes from webpack-dev-server usage with this plugin, that was not the case before... Even with writeToDisk option enabled it doesn't create any SVG sprite file. I will create a reproductible test repository and share here.

Another point, the floatPrecision is not properly applied, even when compilation ends without errors: can you check again please? Some SVG with d="M51.55555555555" ends with d="M51.553", with 3 decimals, like SVGO defaults.

Thanks!

[xavierfoucrier]

@cascornelissen I have just sent you an invite on a private sandbox repository!

• clone repo
• npm i
• npm run dev

Looks like the NPM serve option for webpack-dev-server is the problem.
Until now, it was working fine with v3.

Thanks for the feedback 😉

[Diono]

other thing =>
i did change my output.filename but the scss still keep old value =>
webpack config :

new SVGSpritemapPlugin(...
output: {
    filename: `extra.${Date.now()}`.svg`
}
...)

my generate file scss :

$sprites: (
    'sprite01': "/dist/extra.[contenthash].svg#sprite-sprite01-fragment",
    'sprite02': "/dist/extra.[contenthash].svg#sprite-sprite02-fragment",
)

[contenthash] is not replace or converted... (development mode)

[cascornelissen]

@xavierfoucrier, thanks for the repository, that helped a lot. It's indeed a problem that only pops up in watch mode. It should be fixed in ece1ea4.

These fixes should also resolve the issue with the SVGO plugins not getting applied, using your example repository with floatPrecision: 2, r="35.278888888888" is getting converted to r="35.28".

@Diono, with regards to:

• Your first comment, Cannot read property 'spritemap': after update to v4.0 #163 (comment), please check Cannot read property 'spritemap': after update to v4.0 #163 (comment), this fix and others referenced in this thread are not yet on npm.
• Your second comment, Cannot read property 'spritemap': after update to v4.0 #163 (comment), that should be fixed in e58b1d8.

Can both of you try out these changes and report back?

npm install cascornelissen/svg-spritemap-webpack-plugin#master

[xavierfoucrier]

@cascornelissen I will tomorrow! Thanks 💪

[xavierfoucrier]

Hi @cascornelissen,

Yes I can confirm it works fine 👍
Can you publish a new release today?

Thanks a lot!

[Diono]

it's not fine for me :/
i have a new error at the build now (with cascornelissen/svg-spritemap-webpack-plugin#master)

[Diono]

yes i did a small project of my config => https://github.com/Diono/test

[cascornelissen]

@xavierfoucrier, I've just published 4.0.1 with these fixes.

---

@Diono, thanks, I was hoping for a bit of a smaller repository, it's kind of hard figuring out what's happening when there's tens of additional plugins being loaded, there's CSS files getting generated containing JS, but I took a quick look...

• I don't think it's related to [contenthash] output.filename does not apply to scss url(...) property #139, that issue is about [contenthash] not getting replaced correctly in the styles file but that does seem to be working correctly right now.

• I can not reproduce what you're explaining in Cannot read property 'spritemap': after update to v4.0 #163 (comment). I checked out the repository, ran npm install and npm run dev and it's compiling without errors. You might want to try an rm -rf node_modules/ && npm install?

• I can reproduce what you're explaining in Cannot read property 'spritemap': after update to v4.0 #163 (comment). This is caused by the fact that you're using output.path, output.publicPath, and then also specify sassOptions.outFile which is a combination I've never seen before. Then there's also some additional url function that catches stuff for css-loader which I don't understand.

  You're basically moving files/paths around and this plugin can't keep track of it anymore, it tries to deduce the correct path from output.publicPath which is why it's using /dist/ for the prefix but combining that with output.path and sassOptions.outFile breaks it.

  Then again, I'm getting a bunch of errors like the one below because CSS is being interpreted as JS for some reason so I can't really debug it.

If you can provide a minimal repository that explains this issue I can take another look.

[xavierfoucrier]

@cascornelissen thanks a lot! 😉

[Diono]

I try to debug my project.

I guess when sass-loader read the generated scss file, the sprite.svg is not yet build in the webpack.output.publicPath.
It should be a reason why i have this error Error: Can't resolve '/sprite.1621280929931.svg#sprite-separator-light-middle-fragment' in 'D:\Diono\ousuisje\www\src\scss'

who's the first generated? the sprite svg or the scss file?

[Diono]

OK i found the changes!
before the v4, in the generated scss file, the svg path in background-image:url(...) was prefixed with the output.publicPath
after the v4, it's no more prefixed...

[Diono]

In my sprite.scss i had background-image: url('/dist/sprite.svg#my-fragment')
but now with the v4.0.1 i have
background-image: url('/sprite.svg#my-fragment') ... the /dist/ missing

[cascornelissen]

That's the thing, it should still do that:

svg-spritemap-webpack-plugin/lib/index.js

Lines 284 to 292 in 31e7ace

	publicPath: (() => {
	const publicPath = compilation.options.publicPath;
	if ( typeof publicPath === 'undefined' || publicPath === 'auto' ) {
	return `/${this.filenames.spritemap}`;
	}
	return `${publicPath.replace(/\/$/, '')}/${this.filenames.spritemap}`;
	})()

I was trying to debug why it's not working in your project but there's so many irrelevant things going on in that repository that I can't figure it out easily. While I do enjoy fixing bugs, I don't enjoy spending hours trying to understand some more complicated codebase as much 😅 Which is why I asked for a minimal repository.

You can also debug it yourself, you might get further because you know your codebase. You can just add console.log()s in node_modules/svg-spritemap-webpack-plugin/ (main entry is lib/index.js) to try and see what's going wrong.

[Diono]

yes i understood!
I reduce to the minimal config => https://github.com/Diono/test
without any options, i still have the problem

[cascornelissen]

Nice, that helps a lot.

The error is thrown because css-loader is trying to resolve the URL to the spritemap at compile time which isn't possible. As shown in the fragments example options.url should be set to false, or a function should be passed that returns false for the spritemap specifically, see the css-loader docs for more information.

That fixes the issue during the compilation but there might still be an issue where the path is incorrect when using the compiled code in the browser. I can't really find a way to verify this using your repository, if you're able to incorporate something like html-webpack-plugin to start a development server when executing npm run dev I can take a look at that too, if needed.

I added html-webpack-plugin : https://github.com/Diono/test
If i turn to false the url options in css-loader, the svg url still refer to the root folder (/), not /dist/ (because css-loader not handle this url anymore)

also i have a small warning about division in sass :

DEPRECATION WARNING: Using / for division is deprecated and will be removed in Dart Sass 2.0.0.

Recommendation: math.div(str-length($value), $slice)

More info and automated migrator: https://sass-lang.com/d/slash-div

you should upgrade your generated sass file ;)

Thanks again for the additional information, I'm pretty sure the fix in 7da9664 should resolve the path issue you're running into.

The division symbol deprecation warning should be gone with the changes in 6296251. It's a little more complicated than simply upgrading the generated sass file, other processors such as libsass don't implement math.div ye. Luckily the chunking logic that was there for performance reasons back in the day could be removed.

In the future, creating a separate issue for something totally unrelated is usually the way to go to keep discussions on track ✌🏼

If you could test both of these by installing directly from GitHub, that'd be great! ❤️

npm install cascornelissen/svg-spritemap-webpack-plugin#master
