• Adds webpack config to include font-awesome and font-awesome-loader to be built as dependencies.
• Modifies renderer and index.html to require correct modules based on voyager changes.

Note:

• Have not bumped version
• voyager dependency doesn't have the right version yet.
• This PR cannot be merged until Reduce build size for voyager lib voyager#678 is merged.

@ajainarayanan I though you say the normal lib build works fine -- do we really still need this?

[ajainarayanan]

This is required for font-awesome-sass-loader Since we marked font-awesome-* as external in voyager we need to add this. This is to parse font awesome font files and serve them using url-loader.

[ajainarayanan]

I removed the webpack build step to generate a library build explicitly for electron environment in the voyager PR. This however is required for using font-awesome loader in voyager.

@ssharif6 @FelixCodes -- can you help test if this is still working well?

[ajainarayanan]

@kanitw Have updated the PR. This PR requires the corresponding PR in vega/voyager-server#4 to be merged before this is merged.

I am sorry for the circle of PRs but unless we release a new version of voyager I don't know how we can merge vega/voyager-server#4 and this PR.

Do let me know if there is an easier way.

Note:

Please don't merge this PR yet as the node modules still point to local npm modules.

@FelixCodes -- you mention you have some comments for this PR the other day. Can you post them so @ajainarayanan can take a look?

I am sorry for the circle of PRs but unless we release a new version of voyager I don't know how we can merge vega/voyager-server#4 and this PR.

Oh you can use yarn link command to help link between local projects. :)

[ajainarayanan]

@kanitw I understand yarn link but we cannot merge the voyager-server PR before this one as it depends on this version of voyager. And voyager-electron PR cannot be merged without the changes from voyager-server as voyager-electron depends on these changes. Not sure if I am making sense but thats what I mentioned as circle of PRs.
