You'll need to create one [here](https://www.last.fm/api/account/create) for self-hosting. + +### `LFME_WHITELIST_MODE` (Default: open) +The following(case-insensitive) values are supported: +- `open`: Allow requests for all users. +- `exclusive`: Only allow requests for users in `LFME_WHITELIST`, returning HTTP 403 for all others. `LFME_WHITELIST` _must_ be set if this mode is enabled. + +If the user requested has their listen history private, a 403 will be returned. + +### `LFME_WHITELIST` (Default: "") +This is expected to be a sequence of comma-separated usernames. +Leading/trailing whitespace will be stripped, and unicode is fully supported. + +### `LFME_WHITELIST_REFRESH` (Default: "1m") +The amount of time to cache whitelisted user info for. +It is interpreted as a sequence of `` values, where `num` is a positive integer, +and `suffix` is one of `y`,`mon`,`w`,`d`,`h`,`m`,`s`, `ms`, `µs`, or `ns`, each of which +corresponds to a self-explanatory unit of time. +For most practical applications, one should only use `m` and `s`, as caching your current listen for more than that time has the potential to omit most songs. +Parsing is delegated to the [`duration_str`](https://docs.rs/duration-str/latest/duration_str/) crate, and further info may be found there. + +### `LFME_DEFAULT_REFRESH` (Default: "5m") +The amount of time to cache non-whitelisted user info for. +See `LFME_WHITELIST_REFRESH` for more info. + +### `LFME_PORT` (Default: 9999) +The port to serve on locally. + +### `LFME_THEMES_DIR` +If set, must be a valid path to a directory containing CSS files. +They will be registered as themes on top of the builtin ones, with each theme's name being their filename minus the extension. +Same-named themes will override builtin ones. + +### `LFME_LOG_LEVEL` (Default: Warn) +The loglevel. This is actually parsed as an [`env_logger`](https://docs.rs/env_logger/latest/env_logger) filter string. +Read the docs for more info. + +### `LFME_LOG_FILE` +If set, logs will be written to the specified file. Otherwise, logs are written to `stderr`. + +## Example Configuration +```dotenv +LFME_API_KEY=0123456789abcdef0123456789abcdef +LFME_LOG_LEVEL=error +LFME_PORT=3000 + +LFME_WHITELIST_REFRESH=30s +LFME_WHITELIST_MODE=exclusive +LFME_WHITELIST=a_precious_basket_case, realRiversCuomo, Pixiesfan12345 +``` -- cgit v1.2.3-54-g00ecf
