BrotliOptions 类

每个基于 Brotli 的类都有一个 options 对象。 所有选项都是可选的。

• flush <integer> 默认值: zlib.constants.BROTLI_OPERATION_PROCESS
• finishFlush <integer> 默认值: zlib.constants.BROTLI_OPERATION_FINISH
• chunkSize <integer> 默认值: 16 * 1024
• params <Object> 包含索引 Brotli 参数的键值对象。
• maxOutputLength <integer> 使用便捷方法时限制输出大小。 默认值: buffer.kMaxLength

例如：

const stream = zlib.createBrotliCompress({
  chunkSize: 32 * 1024,
  params: {
    [zlib.constants.BROTLI_PARAM_MODE]: zlib.constants.BROTLI_MODE_TEXT,
    [zlib.constants.BROTLI_PARAM_QUALITY]: 4,
    [zlib.constants.BROTLI_PARAM_SIZE_HINT]: fs.statSync(inputFile).size,
  },
});

Each Brotli-based class takes an options object. All options are optional.

• flush <integer> Default: zlib.constants.BROTLI_OPERATION_PROCESS
• finishFlush <integer> Default: zlib.constants.BROTLI_OPERATION_FINISH
• chunkSize <integer> Default: 16 * 1024
• params <Object> Key-value object containing indexed Brotli parameters.
• maxOutputLength <integer> Limits output size when using convenience methods. Default: buffer.kMaxLength

For example:

const stream = zlib.createBrotliCompress({
  chunkSize: 32 * 1024,
  params: {
    [zlib.constants.BROTLI_PARAM_MODE]: zlib.constants.BROTLI_MODE_TEXT,
    [zlib.constants.BROTLI_PARAM_QUALITY]: 4,
    [zlib.constants.BROTLI_PARAM_SIZE_HINT]: fs.statSync(inputFile).size,
  },
});
