# Observatory

![screenshot](/media/observatory.png)

Observatory was made out of a desire for a high quality and modern disk usage analysis tool

that can be used on all the most popular desktop operating systems. Other alternatives out

there are either old, ugly, confusing, platform specific, or some combination of all of these.

Observatory checks all the boxes that no one else does.

-   Pretty ✔

-   Modern ✔

-   Cross platform ✔

-   Fast ✔ (sort of)

-   Memory efficient ✔ (sort of)

The last two are both things that are kind of work-in-progress. The current scanning

implementation is in TypeScript, which comes with some performance and memory usage concerns.

On a reasonably powerful laptop it's fine, but on some lower end machines it may cause issues.

## Build

To build Observatory, you'll first need to install the latest versions of

[Node](https://nodejs.org) and [Yarn](https://classic.yarnpkg.com).

Install dependencies:

```shell

yarn

```

To run in development:

```shell

yarn dev

```

Build an installer:

```shell

yarn forge

```

## Performance

-   DaisyDisk: 13.20s

-   Observatory: 77.896s

DaisyDisk will probably always be faster since it can optimize specifically for

macOS and runs directly on hardware instead of inside of V8. I'm currently attempting to

rewrite the disk analysis in Rust, which could potentially see a huge improvement in

performance, but that's yet to be proven.

### Goals

Full scan _should_ take less than 20 seconds on a recent/decent MacBook Pro. It

currently takes much longer.
