## 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');
|
|
```
