## Description
There is often a need to get a unique ID for entities, be that for Discord messages/channels/servers, keys in a database or many other similar examples. There are many ways to get such a unique ID, and one of those is using a so-called "snowflake". You can read more about snowflake IDs in [this Medium article](https://medium.com/better-programming/uuid-generation-snowflake-identifiers-unique-2aed8b1771bc).
## Features
- Written in TypeScript
- Bundled with esbuild so it can be used in NodeJS and browsers
- Offers CommonJS, ESM and UMD bundles
- Offers predefined epochs for Discord and Twitter
- Fully tested
## Installation
You can use the following command to install this package, or replace `npm install` with your package manager of choice.
```sh
npm install @sapphire/snowflake
```
## Usage
**Note:** While this section uses `require`, the imports match 1:1 with ESM imports. For example `const { Snowflake } = require('@sapphire/snowflake')` equals `import { Snowflake } from '@sapphire/snowflake'`.
### Constructing snowflakes
#### Snowflakes with custom epoch
```typescript
// Import the Snowflake class
const { Snowflake } = require('@sapphire/snowflake');
// Define a custom epoch
const epoch = new Date('2000-01-01T00:00:00.000Z');
// Create an instance of Snowflake
const snowflake = new Snowflake(epoch);
// Generate a snowflake with the given epoch
const uniqueId = snowflake.generate();
```
#### Snowflake with Discord epoch constant
```typescript
// Import the Snowflake class
const { DiscordSnowflake } = require('@sapphire/snowflake');
// Generate a snowflake with Discord's epoch
const uniqueId = DiscordSnowflake.generate();
// Alternatively, you can use the method directly
const uniqueId = DiscordSnowflake.generate();
```
#### Snowflake with Twitter epoch constant
```typescript
// Import the Snowflake class
const { TwitterSnowflake } = require('@sapphire/snowflake');
// Generate a snowflake with Twitter's epoch
const uniqueId = TwitterSnowflake.generate();
// Alternatively, you can use the method directly
const uniqueId = TwitterSnowflake.generate();
```
### Deconstructing snowflakes
#### Snowflakes with custom epoch
```typescript
// Import the Snowflake class
const { Snowflake } = require('@sapphire/snowflake');
// Define a custom epoch
const epoch = new Date('2000-01-01T00:00:00.000Z');
// Create an instance of Snowflake
const snowflake = new Snowflake(epoch);
// Deconstruct a snowflake with the given epoch
const uniqueId = snowflake.deconstruct('3971046231244935168');
```
#### Snowflake with Discord epoch constant
```typescript
// Import the Snowflake class
const { DiscordSnowflake } = require('@sapphire/snowflake');
// Deconstruct a snowflake with Discord's epoch
const uniqueId = DiscordSnowflake.deconstruct('3971046231244935168');
// Alternatively, you can use the method directly
const uniqueId = DiscordSnowflake.deconstruct('3971046231244935168');
```
#### Snowflake with Twitter epoch constant
```typescript
// Import the Snowflake class
const { TwitterSnowflake } = require('@sapphire/snowflake');
// Deconstruct a snowflake with Twitter's epoch
const uniqueId = TwitterSnowflake.deconstruct('3971046231244935168');
// Alternatively, you can use the method directly
const uniqueId = TwitterSnowflake.deconstruct('3971046231244935168');
```
