Shouldn't we wait until this extension becomes open source?

[adhamfarrag]

We are waiting :)

@adhamfarrag I think nuxtr would be a really great addition to the ecosystem!
Do you have an ETA for open sourcing your extension? I would be happy to contribute some features.

On a side note, I found out about another Nuxt vscode OSS extension https://marketplace.visualstudio.com/items?itemName=cpreston321.nuxt-vscode

@Hebilicious Hey, I think I can open source it before the end of this month. Thanks for offering to help :)

In the meantime, the extension you mentioned is really good but only covers 1 out of 9 features of the initial release of Nuxtr.

@danielroe just open sourced it.
