# pub.solar homepage

This is the repository containing the code for https://pub.solar.

It is built using [lume](https://lume.land/) with JSX. To get started, make sure
you have the [nix package manager](https://nixos.org/download.html) installed.
Then you can start developing with:

### Quick start

```
nix develop
```

This will use a [nix devshell](https://nix.dev/tutorials/first-steps/ad-hoc-shell-environments#ad-hoc-envs)
to create an environment that has [deno](https://deno.land/) and [lume](https://lume.land/)
available.

An alternative approach for loading all dependencies is [`direnv`](https://direnv.net).
It basically runs `nix develop` for you, once you enter a directory which
contains a `.envrc` file and allow it by running `direnv allow`. Once installed
globally, run:

```
direnv allow
```

To get a live development server, run

```
deno task serve
```

Unfortunately, hot module reloading is currently broken for JSX modules, so
you'll need to restart this process regularly during development.

## Updating Open Sans

To update the font files and CSS, run `google-font-downloader $FONT_CSS_URL`.
As "documentation" `flake.nix` shows the internals, and
`_includes/styles/typography.css` has a comment at the top that shows which
command was used to generate it.

### Deployment

Our [Drone CI](https://ci.pub.solar/pub-solar/pub.solar) is configured to
deploy the `main` branch to the production website. To integrate any changes,
first create a pull request, which will be reviewed. After merging it, the new
version will get deployed automatically.

### Troubleshooting

When running `deno task serve`, if you see an error message like:

```
NotFound: No such file or directory (os error 2): stat '/home/<user>/.../git.pub.solar/pub-solar/pub.solar/.direnv/flake-inputs/5acdh8xyry0kdvp6xla2hw7wf3zkphkl-source/pkgs/test/nixpkgs-check-by-name/tests/symlink-invalid/pkgs/by-name/fo/foo/foo.nix'

  name: "NotFound",
  code: "ENOENT"
}
```

try removing the .direnv directory:

```
rm -rf .direnv
deno task serve
```

Another common error message after updating dependencies is:

```
22.31 error: The source code is invalid, as it does not match the expected hash in the lock file.
```

To recreate the deno lock file, run

```
deno cache --lock=deno.lock --lock-write _config.ts
```
