Package Exports

didyoumean3

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (didyoumean3) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

use case

base use

import didyoumean3 from 'didyoumean3'
// or
const { didyoumean3 } = require('didyoumean3');

let input = 'insargrm'
let list = [
  'facebook', 'INSTAgram', ' in stagram', 'baidu', 'twitter', 'wechat', 'instagram', 'linkedin'
]

didyoumean3(input, list)

// will output:
// {
//   winner: 'instagram',
//   matches: [
//     {
//       score: 8,
//       target: 'facebook',
//     },
//     {
//       score: 3,
//       target: 'instagram',
//     },
//     {
//       score: 7,
//       target: 'linkedin',
//     },
//     // ...
//   ],
// }

optional configuration

didyoumea3 has some built-in string formatting configuration items：

ignore: default is false, Case-insensitive
trim: default is true, will use string.trim format the string
trimAll: defalut is false, will trim with regexp /\s+/g
diacritics: default is false, just 'café' -> 'café'.normalize()
normalize: customize the formatting function by yourself

🔥If these parameters don't meet your requirements, you can customize the formatting function through normalize.

🔥When using the custom normalize function, the above string formatting configurations will fail

didyoumean3(input, target, { normalize: (s: string) => s.trim() } );

val: sometimes, you need to match against a list of object. you can use val to get the target string out.

let l = [
  { id: 'facebook' },
  { id: 'baidu' },
  { id: 'twitter' },
  { id: 'INSTAgram' },
  { id: ' in stagram' },
  { id: 'wechat' },
  { id: 'instagram' },
  { id: 'linkedin' },
];

didyoumean3(input, target, { val: item => item.id } );

result: Customize the structure of the results you want to return

type Res = null | { matches: any[], winner: string }
const result = (res: Res) => {
  if (!res) return 'nothing matched!'
  else return res
}

didyoumean3(input, target, { result } );

filter: You can filter the results you want, such as those with a score greater than 5

let i2 = 'insargrm';
let l2 = ['facebook', 'instagram', 'linkedin'];
expect(
  didyoumean3(i2, l2, { filter: (score: number, item: any) => score >= 7 })
    ?.matches.length
).toBe(2);
