# nlw-api
A simple API that caches and allows you to fetch data from the [Non-Listworthy Extreme Demons spreadsheet](https://docs.google.com/spreadsheets/d/1YxUE2kkvhT2E6AjnkvTf-o8iu_shSLbuFkEFcZOvieA/edit) (and [Insane Demon Spreadsheet](https://docs.google.com/spreadsheets/d/15ehtAIpCR8s04qIb8zij9sTpUdGJbmAE_LDcfVA3tcU/edit)!) running on `https://nlw.oat.zone/`. Originally made for the [NLW Integration](https://geode-sdk.org/mods/oatmealine.nlw_integration/) Geode mod, but free for anyone to use.
## Documentation
### Endpoints
#### `/list?type={type}`
Fetches the entire list as a JSON, including levels of type `type`. `type` can be `regular`, `pending`, `platformer` or `all` and defaults to `regular`.
**Returns**: An array of [`NLWLevel`](#nlwlevel--level)s.
#### `/ids?type={type}`
Fetches the IDS list as a JSON, including levels of type `type`. `type` can be `regular`, `platformer` or `all` and defaults to `regular`. **Experimental.**
**Returns**: An array of [`IDSLevel`](#idslevel-level)s.
### Objects
#### `Level`
Represents a generic level.
- `sheetIndex`: The row index of the level on the associated spreadsheet. 0-indexed.
- `id`: The ID of the level, manifested from the sheet using dark magic. Can be `undefined` very rarely.
- `name`: The name of the level. Standardized to the in-game level name.
- `creator`: The creator(s) of the level, as listed on the sheet.
- `description`: Descriptions and notes as listed on the sheet.
#### `NLWLevel` : [`Level`](#level)
Represents an NLW level.
- `tier`: `"Fuck"`, `"Beginner"`, `"Easy"`, `"Medium"`, `"Hard"`, `"Very Hard"`, `"Insane"`, `"Extreme"`, `"Remorseless"`, `"Relentless"` or `"Terrifying"`.
- `skillset`: Level skillset, as listed on the sheet.
- `enjoyment`: Level enjoyment sampled from EDEL as a number, or `null`.
- `broken`: If the level is broken in 2.2. `"no"`, `"slightly"`, `"very"`, `"absolutely destroyed"` or rarely `null` if unknown.
#### `IDSLevel`: [`Level`](#level)
Represents an IDS level.
- `tier`: `"Fuck"`, `"Beginner"`, `"Easy"`, `"Medium"`, `"Hard"`, `"Very Hard"`, `"Insane"` or `"Extreme"`.
- `skillset`: Level skillset, as listed on the sheet.
- `broken`: If the level is broken in 2.2. `"no"`, `"yes"`, or rarely `null` if unknown.
### Self-hosting
You can self-host the API yourself, if you so wish! Here's the rough steps:
1. Grab yourself a Google Sheets API key. This may sound extremely intimidating, but you can create a read-only Sheets API key with not much hassle with [this guide](https://theoephraim.github.io/node-google-spreadsheet/#/guides/authentication?id=api-key).
2. Install, either with NPM or Nix:
1. With NPM, run:
```sh
npm install
```
Then, you can start it with:
```sh
API_KEY=... node index.js
```
**However**, take note of the [environment variables](#environment-variables) available to use.
2. Use Nix to either just plainly run it:
```sh
API_KEY=... nix run git+https://git.oat.zone/oat/nlw-api
```
Or import it into your system flake like so:
```nix
nlw-api.url = "git+https://git.oat.zone/oat/nlw-api";
# in your `nixosConfiguration`:
imports = [
inputs.nlw-api.nixosModules.nlw-api
];
```
Afterwards, you can use it as a regular NixOS service:
```nix
services.nlw-api = {
enable = true;
domain = "nlw.oat.zone";
apiKey = builtins.readFile /etc/sheets-api-key;
port = 1995;
};
```
3. You're done! It will take a while to fetch every level and their IDs initially, but in time you will have yourself the caches set up and the server up and running.
### Environment variables
You can pass these into the server as config (an `.env` file will **not** work):
- `API_KEY`: A Google API key - see [this guide](https://theoephraim.github.io/node-google-spreadsheet/#/guides/authentication?id=api-key) to see how to get one hassle-free
- `PORT`: The HTTP port to host the server on
- `CACHE_DIR`: The directory to store cached data in, defaults to `./cache/`
