Error: Module not found: Error: Can't resolve './libzopfli-wasm'

[aaltotsky]

I'm trying to integrate @gfx/zopfli into my Angular9 app. When I run build I got an error:

ERROR in ./node_modules/@gfx/zopfli/dist/libzopfli.js
Module not found: Error: Can't resolve './libzopfli-wasm' in 'C:\Dev\MyApp\ClientApp\node_modules\@gfx\zopfli\dist'

I'm using it as it described in the readme:

import { gzip  } from "@gfx/zopfli";

// All regular routes use the Universal engine
    server.get('*', async (req, res) => {
        res.render(indexHtml, { req }, (_err, html) => {
            if (req.header('Accept-Encoding').includes('gzip')) {
                gzip(html, { numiterations: 15 }, (_err, output) => {
                    // output is compressed in gzip
                    res.set('Content-Encoding', 'gzip');
                    res.send(output);
                });
            }
            else {
                res.send(html);
            }
        });
    });

In the package.json I have: @gfx/zopfli": "^1.0.14" Any suggestions?

Same here

[jimmykane]

Did you manage to solve this ?

[gfx]

Hmm. Can you explain more? For example, minimum reproducable code should help me.

I never use this module with Angular, but I use this module long time with NodeJS v10 and v12.

[jimmykane]

Well if you try to use it it fails :-)

[aaltotsky]

I moved away and end up using compression "compression": "^1.7.4" import * as compression from 'compression';

[aaltotsky]

@gfx I think you just need to include the libzopfli-wasm into the distribution package.

@aaltotsky I am using Pako. Was looking which also uses gzip and deflate and works superb.

Same Problem. Im looking for brotli compression and 'pako' and 'compression' don't support it. It would be amazing if you could fix this problem
