Allow a way to install js library using npm

[krishnakg]

It would be very convenient if this excellent library can be installed using npm similar to other libraries like chess.js.

See my work on #147 (all done on a branch). If the documentation is right, it should be easy to publish it then on NPM. Stay tuned ...

Is the installation with npm working correctly for you guys?

I am not so experienced with npm installations, but if I try other packages I don't get these errors. I tried for example to install "@mliebelt/pgn-parser": "^1.4.9" and @mliebelt/pgn-reader": "^1.2.20", they both worked fine for me :S

Any idea?

[mliebelt]

@eschiendorfer Could you be more concrete on what you are doing and why? The following works:

• Have a Javascript application with `package.json´
• Add the library as a dependency.
• Use one of the ways to include it then in your context (HTML mostly)

I will add later this week a current example (when hunting a bug) how to installation could be done.

What is your expectation what your command should do? If you want to have that library only, there should be better ways to do it.

[mliebelt]

Just tried it, did the following:

1. Go to a new directory.
2. Do the command npm install @mliebelt/pgn-viewer
3. Wait ...

As a result, you get the following directory structure

package.json
package-lock.json
node_modules/
  @mliebelt/
    pgn-viewer/
      lib/
        dist.js
        dist.js.gz
        dist.js.map
        ...

and many other files. The only file you need in the context of a browser is either dist.js or dist.js.zip.

[eschiendorfer]

@mliebelt Yeah this is basically what I do. But the "npm install @mliebelt/pgn-viewer" leads to the errors above. Strangely I don't get this for "npm install @mliebelt/pgn-reader" as an example. But yeah, it's probably a misconfiguration on my machine... I will try to investigate it. Anyway: thanks a lot for your fast response and the viewer in general. It looks promising!

[mliebelt]

Hopefully you can solve it for yourself. I have no windows machine at hand (and no, that is no fun to do serious console work in windows). Have you tried to use WSL (Linux in a windows subsystem) and use npm there?

[eschiendorfer]

No I haven't tried WSL yet. I use such things like npm/composer maybe once in 6 months. Sometimes it works like a charm and sometimes it is headscratching ^^ But ok I also can try to use another computer :) Maybe I have more luck there or at least get a better understanding of the possible issue.
