86 | ### Pool options types declaration merge |
87 | ||
88 | `FixedThreadPoolOptions` and `DynamicThreadPoolOptions` type declarations have been merged to `PoolOptions<Worker>`. | |
89 | ||
fa0f5b28 S |
90 | #### New `export` strategy |
91 | ||
92 | ```js | |
93 | // Before | |
777b7824 | 94 | const DynamicThreadPool = require('poolifier/lib/dynamic') |
fa0f5b28 | 95 | // After |
777b7824 | 96 | const { DynamicThreadPool } = require('poolifier/lib/dynamic') |
fa0f5b28 S |
97 | ``` |
98 | ||
99 | But you should always prefer just using | |
100 | ||
101 | ```js | |
777b7824 | 102 | const { DynamicThreadPool } = require('poolifier') |
fa0f5b28 S |
103 | ``` |
104 | ||
d3c8a1a8 S |
105 | #### New type definitions for input data and response |
106 | ||
ec2ccfc8 | 107 | For cluster worker and worker-thread pools, you can now only send and receive serializable data. |
d3c8a1a8 S |
108 | _This is not a limitation by poolifier but NodeJS._ |
109 | ||
3a4b605f | 110 | #### Public property replacements |
5c5a1fb7 | 111 | |
3a4b605f | 112 | `numWorkers` property is now `numberOfWorkers` |
5c5a1fb7 | 113 | |
280c2a77 | 114 | #### Internal (protected) properties and methods renaming |
fa0f5b28 | 115 | |
280c2a77 S |
116 | These properties are not intended for end users |
117 | ||
118 | - `id` => `nextMessageId` | |
119 | ||
120 | These methods are not intended for end users | |
fa0f5b28 S |
121 | |
122 | - `_chooseWorker` => `chooseWorker` | |
280c2a77 | 123 | - `_newWorker` => `createWorker` |
fa0f5b28 S |
124 | - `_execute` => `internalExecute` |
125 | - `_chooseWorker` => `chooseWorker` | |
126 | - `_checkAlive` => `checkAlive` | |
127 | - `_run` => `run` | |
