Options
reserveText
Type: String
Default: ''
Text to be reserved. This option can be used in certain scenarios where data obtained by sending a request needs to be displayed on the page and fonts are used. The reserved font glyphs you specify will be retained during packaging.
filter
Type: (text: string) => string
Default: null
Filter text to keep only what is needed
This is an example: compress only specified characters, e.g. only CJK (CJK Unified Ideographs) characters
function getCJK(str) {
const reg = /[\u4E00-\u9FA5\u3040-\u30FF\u31F0-\u31FF\uFF00-\uFF9F\u3000-\u303F\uFF01-\uFF0F\uFF1A-\uFF20\uFF3B-\uFF40\uFF5B-\uFF60\uFFE0-\uFFE6]/g
const cjkChars = str.match(reg)
return cjkChars ? cjkChars.join('') : ''
}
plugins: [
fontmin({
filter(text) {
return getCJK(text)
}
})
]
