1062 | ||
1063 | `FixedThreadPoolOptions` and `DynamicThreadPoolOptions` type declarations have been merged to `PoolOptions<Worker>`. | |
1064 | ||
fa0f5b28 S |
1065 | #### New `export` strategy |
1066 | ||
1067 | ```js | |
1068 | // Before | |

fa0f5b28 | 1070 | // After |
0eee77cb | 1071 | const { DynamicThreadPool } = require('poolifier/lib/dynamic') |
fa0f5b28 S |
1072 | ``` |
1073 | ||
1074 | But you should always prefer just using | |
1075 | ||
1076 | ```js | |
0eee77cb | 1077 | const { DynamicThreadPool } = require('poolifier') |
fa0f5b28 S |
1078 | ``` |
1079 | ||
d3c8a1a8 S |

fa0f5b28 | 1090 | |
280c2a77 S |
1091 | These properties are not intended for end users |
1092 | ||
1093 | - `id` => `nextMessageId` | |
1094 | ||
1095 | These methods are not intended for end users | |
fa0f5b28 S |
1096 | |
1097 | - `_chooseWorker` => `chooseWorker` | |
280c2a77 | 1098 | - `_newWorker` => `createWorker` |
fa0f5b28 S |
1099 | - `_execute` => `internalExecute` |
