1179 | ||
1180 | `FixedThreadPoolOptions` and `DynamicThreadPoolOptions` type declarations have been merged to `PoolOptions<Worker>`. | |
1181 | ||
fa0f5b28 S |
1182 | #### New `export` strategy |
1183 | ||
1184 | ```js | |
1185 | // Before | |

0eee77cb | 1188 | const { DynamicThreadPool } = require('poolifier/lib/dynamic') |
fa0f5b28 S |
1189 | ``` |
1190 | ||
1191 | But you should always prefer just using | |
1192 | ||
1193 | ```js | |
0eee77cb | 1194 | const { DynamicThreadPool } = require('poolifier') |
fa0f5b28 S |
1195 | ``` |

fa0f5b28 | 1207 | |
280c2a77 S |
1208 | These properties are not intended for end users |
1209 | ||
1210 | - `id` => `nextMessageId` | |
1211 | ||
1212 | These methods are not intended for end users | |
fa0f5b28 S |
1213 | |
1214 | - `_chooseWorker` => `chooseWorker` | |
280c2a77 | 1215 | - `_newWorker` => `createWorker` |
fa0f5b28 S |
1216 | - `_execute` => `internalExecute` |
