1378 | ### Pool options types declaration merge |
1379 | ||
1380 | `FixedThreadPoolOptions` and `DynamicThreadPoolOptions` type declarations have been merged to `PoolOptions<Worker>`. | |
1381 | ||
fa0f5b28 S |
1382 | #### New `export` strategy |
1383 | ||
1384 | ```js | |
1385 | // Before | |
0eee77cb | 1386 | const DynamicThreadPool = require('poolifier/lib/dynamic') |
fa0f5b28 | 1387 | // After |
0eee77cb | 1388 | const { DynamicThreadPool } = require('poolifier/lib/dynamic') |
fa0f5b28 S |
1389 | ``` |
1390 | ||
1391 | But you should always prefer just using | |
1392 | ||
1393 | ```js | |
0eee77cb | 1394 | const { DynamicThreadPool } = require('poolifier') |
fa0f5b28 S |
1395 | ``` |
1396 | ||
d3c8a1a8 S |
1397 | #### New type definitions for input data and response |
1398 | ||
6677a3d3 | 1399 | For cluster worker and worker-thread pools, you can now only send and receive structured-cloneable data. |

d3c8a1a8 | 1401 | |
3a4b605f | 1402 | #### Public property replacements |
5c5a1fb7 | 1403 | |

1408 | These properties are not intended for end users |
1409 | ||
1410 | - `id` => `nextMessageId` | |
1411 | ||
1412 | These methods are not intended for end users | |
fa0f5b28 S |
1413 | |
1414 | - `_chooseWorker` => `chooseWorker` | |
280c2a77 | 1415 | - `_newWorker` => `createWorker` |
fa0f5b28 S |
1416 | - `_execute` => `internalExecute` |
1417 | - `_chooseWorker` => `chooseWorker` | |
