Use this package for getting stable unique strings with fixed length.

Api

/**
 *
 * @param str - input str, no important how long it is
 * @param options
 *   maxLength - max length of output value, default is 250
 *   humanizeHash - use hash of words, not for hex, default true
 *   words - count of words in humanized hash
 *   length - count of bytes if not humanized hash
 */
function humanizeHashLongStr(str, options = {}) {}

Examples

const { humanizeHashLongStr } = require('humanize-hash-long-str')

const longStr = 'ABCDEFGHIJKLMNOPQRSTUVWXYZ1234567890abcdefghjijklmnopqrstuvwxyz'

console.log(humanizeHashLongStr(longStr, { maxLength: 20 }))

Will return ABCD_mango-jazz-papa, because maximum length is 20 symbols, and humanized hash from full string with 3 words is mango-jazz-papa

You can change words count:

console.log(humanizeHashLongStr(longStr, { maxLength: 20, words: 2 }))

Will return ABCDEFG_lamp-sixteen

Also, you can use non-humanized hash, instead of words this utility will use simple base64 encoding of raw bytes. For example:

console.log(humanizeHashLongStr(longStr, { maxLength: 30, humanizeHash: false }))

Will return ABCDEFGHIJKLM_38eJ9+grhaK+cQ==

You can change bytes length:

console.log(humanizeHashLongStr(longStr, { maxLength: 30, humanizeHash: false, length: 5 }))

Will return ABCDEFGHIJKLMNOPQRSTU_kTSZcAE=
