| js Number 类型最大数值:9007199254740992(16位), | |||
| 在JS中没有bigint类型,所以建议将ID控制在16位以内,统一使用number类型 | |||
| ## 使用 | |||
| ### 1.文件引用 | |||
| ```js | |||
| import { snowflakeIdv1 } from '../snowflakeIdv1' | |||
| const WorkerId = process.env.WorkerId == undefined ? 1 : process.env.WorkerId | |||
| let gen1 = new snowflakeIdv1({ WorkerId: WorkerId}) | |||
| let id1 = gen1.NextId() | |||
| console.log(id1, id1.toString().length) | |||
| ``` | |||
| ### 2.npm库安装 | |||
| ```sh | |||
| npm i simple-flakeid | |||
| ``` | |||
| ```js | |||
| const snowId = require('simple-flakeid') | |||
| let gen1 = new snowId.SnowflakeIdv1({ workerId: 1 }) | |||
| for (let i = 0; i < 10; i++) { | |||
| let id1 = gen1.NextId() | |||
| console.log(`${i} ID:${id1} ${typeof id1} length:${id1.toString().length}`) | |||
| } | |||
| ``` | |||
| ## function | |||
| ### function NextId() | |||
| 根据输出数值判断,小于number最大值时输出number类型,大于时输出bigint | |||
| ### function NextNumber() | |||
| 始终输出number类型,超过时throw error | |||
| ### function NextBigId() | |||
| 始终输出bigint类型 | |||
| ## 测试 | |||
| ```bash | |||
| ts-node test/test1.ts | |||
| ``` | |||
| ## 使用 | |||
| ```js | |||
| import { snowflakeIdv1 } from '../snowflakeIdv1' | |||
| const WorkerId = process.env.WorkerId == undefined ? 1 : process.env.WorkerId | |||
| let gen1 = new snowflakeIdv1({ WorkerId: WorkerId}) | |||
| let id1 = gen1.NextId() | |||
| console.log(id1, id1.toString().length) | |||
| ``` | |||
| ## 示例 | |||
| ```js | |||
| import { snowflakeIdv1 } from '../snowflakeIdv1' | |||
| const WorkerId = process.env.WorkerId == undefined ? 1 : process.env.WorkerId | |||
| let gen1 = new snowflakeIdv1({ WorkerId: WorkerId, SeqBitLength: 6 }) | |||
| for (let i = 0; i < 10; i++) { | |||

| ## 同时兼容number和bigint的写法 | |||
| 如果您觉得这个用法更好,可以手动替换对应方法 | |||
| ```js | |||
| /** | |||
| * 生成ID | |||
| * @returns | |||
| */ | |||
| public NextId(): number | bigint { | |||
| if (this._IsOverCost) { | |||
| // | |||
| let id = this.NextOverCostId() | |||
| if (id >= 9007199254740992n) | |||
| return id | |||
| else | |||
| return parseInt(id.toString()) | |||
| } else { | |||
| // | |||
| let id = this.NextNormalId() | |||
| if (id >= 9007199254740992n) | |||
| return id | |||
| else | |||
| return parseInt(id.toString()) | |||
| } | |||
| } | |||

| ## 其他帮助 | |||
| 在mysql中int类型最大长度是10位数字,由于本算法默认生成的是15位,最短也是11位,所以在mysql中需要使用bigint数据类型 | |||
