Add via npm

$ npm install postcss-design-px-to-rpx --save-dev

or yarn

$ yarn add -D postcss-design-px-to-rpx Usage

Default Options:

{ unitToConvert: 'DP', viewportWidth: 414, unitPrecision: 5, propList: ['*'], viewportUnit: 'rpx', fontViewportUnit: 'rpx', selectorBlackList: [], exclude: undefined, include: undefined } unitToConvert (String) unit to convert, by default, it is DP. viewportWidth (Number) The width of the viewport. unitPrecision (Number) The decimal numbers to allow the vw units to grow to. propList (Array) The properties that can change from px to vw. Values need to be exact matches. Use wildcard * to enable all properties. Example: ['*'] Use * at the start or end of a word. (['position'] will match background-position-y) Use ! to not match a property. Example: ['*', '!letter-spacing'] Combine the "not" prefix with the other prefixes. Example: ['', '!font'] viewportUnit (String) Expected units. fontViewportUnit (String) Expected units for font. selectorBlackList (Array) The selectors to ignore and leave as px. If value is string, it checks to see if selector contains the string. ['body'] will match .body-class If value is regexp, it checks to see if the selector matches the regexp. [/^body$/] will match body but not .body exclude (Regexp or Array of Regexp) Ignore some files like 'node_modules' If value is regexp, will ignore the matches files. If value is array, the elements of the array are regexp. include (Regexp or Array of Regexp) If include is set, only matching files will be converted, for example, only files under src/mobile/ (include: /\/src\/mobile\//) If the value is regexp, the matching file will be included, otherwise it will be excluded. If value is array, the elements of the array are regexp.

exclude and include can be set together, and the intersection of the two rules will be taken.
