- When installing a package on Node v8 (or whatever npm version ships with it - v5), all packages not listed in `package.json` are removed. Since we explicitly added `--no-save`, installing a theme would delete the previous one. I am now checking that the file already exists or not. This means that it will still happen to people the next time they run `thelounge install`, because the previous install did not save into `package.json` :/
- Adding `--save` to make sure that the same, correct behavior is done on Node v6 as well (npm v3)
- Adding `--save-exact` for good measure.
Without this, going to `https://thelounge.example.com/index.html` would return the raw file. This now excludes it from the `public` folder so it cannot be rendered as is.
Renaming the file is for good measure, to indicate that this HTML file must be templated. Because it is a straight rename with no modification, rebasing PRs on it should not be to painful, as git re-applies changes on renamed files.
- Exit with code 1 when package was not installed
- Run a pre-step to check if package is installed before uninstalling. I have tried every possible way I could think of without that first `npm list` step based on output of `npm uninstall`, but different npm versions produce different outputs, so there is nothing reliable. This is a more robust way to do so anyway.
- Consolidate error handlers
It is on purpose that the message is the same than when a package was not installed. From a user standpoint, it only matters that this specific package was not installed.
- Hides progress bars that flash when installing/uninstalling as it does not bring real value here, at least for now
- Inform user if package being uninstalled was not actually installed
- Do not display npm outputs, mention which version was installed (this will probably need refining when installing packages with dependencies)
- There is no client caching of the changelog/version anymore. Instead, server returns the expiration date of its cache, and that is used by the client as well.
- There is now a "Check now" button on the client that appears when data is stale. This means that info is fetched only once and never refreshed (it was refreshed every hour before) unless the user explicitly wants to check latest version, which in turn is as stale as server info is, i.e. 15 minutes max.
- Button style is shared with the "Join a channel" feature, `.btn-small` (not `.btn-sm` to be explicit that this is not a Bootstrap thing).
- Version checker content is now centralized in the `version_checker` template, instead of being partially in the checker template, partially in the Help template, and partially in the code.
- A "Try again" button lets user attempt to fetch info instead of forcing them to reload the page.
- Use Flexbox to display a nicer version checker: icon is slightly bigger, and button is always aligned on the right.
- Changelog logic has been removed from `lounge.js` and moved into the component file.
- Changelog template is only passed what it needs instead of everything the server gives us.
- Public version now displays version checker, since server is caching things.
- Cleaner code overall.
