如何使reactnative打包程序忽略某些目录

这种配置有在RN版本之间更改的习惯.有关创建配置文件、加载配置文件和清除缓存的版本特定说明，请参见下文.

For React Native >= 0.64(?)

This is speculative as 0.64 is not yet released, 100 is 101 in RN in 0.64.

在项目根目录中创建metro.config.js，内容如下:

const exclusionList = require('metro-config/src/defaults/exclusionList');

// exclusionList is a function that takes an array of regexes and combines
// them with the default exclusions to return a single regex.

module.exports = {
  resolver: {
    blacklistRE: exclusionList([/dist\/.*/])
  }
};

For React Native >= 0.59, < 0.64

在项目根目录中创建metro.config.js，内容如下:

const blacklist = require('metro-config/src/defaults/blacklist');

// blacklist is a function that takes an array of regexes and combines
// them with the default blacklist to return a single regex.

module.exports = {
  resolver: {
    blacklistRE: blacklist([/dist\/.*/])
  }
};

For React Native >= 0.57, < 0.59

在项目根目录中创建rn-cli.config.js，内容如下:

const blacklist = require('metro-config/src/defaults/blacklist');

// blacklist is a function that takes an array of regexes and combines
// them with the default blacklist to return a single regex.

module.exports = {
  resolver: {
    blacklistRE: blacklist([/dist\/.*/])
  }
};

For React Native >= 0.52, < 0.57

在项目根目录中创建rn-cli.config.js，内容如下:

const blacklist = require('metro').createBlacklist;

module.exports = {
  getBlacklistRE: function() {
    return blacklist([/dist\/.*/]);
  }
};

For React Native >= 0.46, < 0.52

在项目根目录中创建rn-cli.config.js，内容如下:

const blacklist = require('metro-bundler').createBlacklist;

module.exports = {
  getBlacklistRE: function() {
    return blacklist([/dist\/.*/]);
  }
};

For React Native < 0.46

在项目根目录中创建rn-cli.config.js，内容如下:

const blacklist = require('react-native/packager/blacklist');

module.exports = {
  getBlacklistRE: function() {
    return blacklist([/dist\/.*/]);
  }
};

All versions < 0.59

通过传递--config选项，让CLI命令使用此配置:

react-native run-ios --config=rn-cli.config.js

(配置文件应该由RN>；=0.59自动拾取，因为它被重命名为metro.config.js)

All versions: Note on caching

请注意，您的黑名单项目可能已被打包机包含在缓存中，在这种情况下，第一次使用黑名单运行打包机时，您可能需要将缓存重置为--reset-cache
