minijson: minify json files with support for comments
minijson --file file1.json --file file2.json
minijson --file file1_with_comment.json --file file2_with_comment.json --comment
minijson --string '{"some_json": "string_here"}'
minijson --string '{"some_json": "string_here"} //comment' --comment
More information at https://github.com/aminya/minijson
--file an array of files to minify
--string a json string to minify
--comment a flag to support comments in json
-h --help This help information.import { minifyFiles, minifyString } from "minijson"
// minify the files in-place and in parallel
await minifyFiles(["file1.json", "file2.json"])
// supports comments by passing true as the second argument
await minifyFiles(["file1_with_comment.json", "file2_with_comment.json"], true)
// minify the given string
const minifiedString = minifyString(`{"some_json": "here"}`)
// supports comments by passing true as the second argument
const minifiedString2 = minifyString(`{"some_json": "here"}//comment`, true)Note: in the Nodejs API, prefer minifyFiles over other functions, as it minifies the files in parallel with the least amount of resources.
