1376 | ### Pool options types declaration merge |
1377 | ||
1378 | `FixedThreadPoolOptions` and `DynamicThreadPoolOptions` type declarations have been merged to `PoolOptions<Worker>`. | |
1379 | ||
fa0f5b28 S |
1380 | #### New `export` strategy |
1381 | ||
1382 | ```js | |
1383 | // Before | |
0eee77cb | 1384 | const DynamicThreadPool = require('poolifier/lib/dynamic') |
fa0f5b28 | 1385 | // After |
0eee77cb | 1386 | const { DynamicThreadPool } = require('poolifier/lib/dynamic') |
fa0f5b28 S |
1387 | ``` |
1388 | ||
1389 | But you should always prefer just using | |
1390 | ||
1391 | ```js | |
0eee77cb | 1392 | const { DynamicThreadPool } = require('poolifier') |
fa0f5b28 S |
1393 | ``` |
1394 | ||
d3c8a1a8 S |
1395 | #### New type definitions for input data and response |
1396 | ||
6677a3d3 | 1397 | For cluster worker and worker-thread pools, you can now only send and receive structured-cloneable data. |

d3c8a1a8 | 1399 | |
3a4b605f | 1400 | #### Public property replacements |
5c5a1fb7 | 1401 | |

fa0f5b28 | 1405 | |
280c2a77 S |
1406 | These properties are not intended for end users |
1407 | ||
1408 | - `id` => `nextMessageId` | |
1409 | ||
1410 | These methods are not intended for end users | |
fa0f5b28 S |
1411 | |
1412 | - `_chooseWorker` => `chooseWorker` | |
280c2a77 | 1413 | - `_newWorker` => `createWorker` |
fa0f5b28 S |
1414 | - `_execute` => `internalExecute` |
1415 | - `_chooseWorker` => `chooseWorker` | |
1416 | - `_checkAlive` => `checkAlive` | |
1417 | - `_run` => `run` | |
