109 | ### Pool options types declaration merge |
110 | ||
111 | `FixedThreadPoolOptions` and `DynamicThreadPoolOptions` type declarations have been merged to `PoolOptions<Worker>`. | |
112 | ||
fa0f5b28 S |
113 | #### New `export` strategy |
114 | ||
115 | ```js | |
116 | // Before | |
777b7824 | 117 | const DynamicThreadPool = require('poolifier/lib/dynamic') |
fa0f5b28 | 118 | // After |
777b7824 | 119 | const { DynamicThreadPool } = require('poolifier/lib/dynamic') |
fa0f5b28 S |
120 | ``` |
121 | ||
122 | But you should always prefer just using | |
123 | ||
124 | ```js | |
777b7824 | 125 | const { DynamicThreadPool } = require('poolifier') |
fa0f5b28 S |
126 | ``` |
127 | ||
d3c8a1a8 S |
128 | #### New type definitions for input data and response |
129 | ||
ec2ccfc8 | 130 | For cluster worker and worker-thread pools, you can now only send and receive serializable data. |
d3c8a1a8 S |
131 | _This is not a limitation by poolifier but NodeJS._ |
132 | ||
3a4b605f | 133 | #### Public property replacements |
5c5a1fb7 | 134 | |
3a4b605f | 135 | `numWorkers` property is now `numberOfWorkers` |
5c5a1fb7 | 136 | |
280c2a77 | 137 | #### Internal (protected) properties and methods renaming |
fa0f5b28 | 138 | |
280c2a77 S |
139 | These properties are not intended for end users |
140 | ||
141 | - `id` => `nextMessageId` | |
142 | ||
143 | These methods are not intended for end users | |
fa0f5b28 S |
144 | |
145 | - `_chooseWorker` => `chooseWorker` | |
280c2a77 | 146 | - `_newWorker` => `createWorker` |
fa0f5b28 S |
147 | - `_execute` => `internalExecute` |
148 | - `_chooseWorker` => `chooseWorker` | |
149 | - `_checkAlive` => `checkAlive` | |
150 | - `_run` => `run` | |
