```json { "presets": [["minify", { "mangle": { "exclude": ["MyCustomError"] }, "unsafe": { "typeConstructors": false }, "keepFnName": true }]] } ``` ### Via CLI ```sh babel script.js --presets minify ``` ### Via Node API ```javascript const babel = require("@babel/core"); const fs = require("fs"); const code = fs.readFileSync("./input.js").toString(); const minified = babel.transform(code, { presets: ["minify"] }); ``` ## Options Two types of options: 1. 1-1 mapping with plugin 2. The same option passed to multiple plugins #### 1-1 mapping with plugin + `false` - disable plugin + `true` - enable plugin + `{ ...pluginOpts }` - enable plugin and pass pluginOpts to plugin OptionName | Plugin | DefaultValue ---------- | ------ | ------------ booleans | [transform-minify-booleans][booleans] | true builtIns | [minify-builtins][builtIns] | true consecutiveAdds | [transform-inline-consecutive-adds][consecutiveAdds] | true deadcode | [minify-dead-code-elimination][deadcode] | true evaluate | [minify-constant-folding][evaluate] | true flipComparisons | [minify-flip-comparisons][flipComparisons] | true guards | [minify-guarded-expressions][guards] | true infinity | [minify-infinity][infinity] | true mangle | [minify-mangle-names][mangle] | true memberExpressions | [transform-member-expression-literals][memberExpressions] | true mergeVars | [transform-merge-sibling-variables][mergeVars] | true numericLiterals | [minify-numeric-literals][numericLiterals] | true propertyLiterals | [transform-property-literals][propertyLiterals] | true regexpConstructors | [transform-regexp-constructors][regexpConstructors] | true removeConsole | [transform-remove-console][removeConsole] | false removeDebugger | [transform-remove-debugger][removeDebugger] | false removeUndefined | [transform-remove-undefined][removeUndefined] | true replace | [minify-replace][replace] | true simplify | [minify-simplify][simplify] | true simplifyComparisons | [transform-simplify-comparison-operators][simplifyComparisons] | true typeConstructors | [minify-type-constructors][typeConstructors] | true undefinedToVoid | [transform-undefined-to-void][undefinedToVoid] | true #### The same option passed to multiple plugins + When multiple plugins require the same option, it's easier to declare it in one place. These options are passed on to two or more plugins.
