# Type.js
**Typo.js** is a JavaScript spellchecker that uses Hunspell-style dictionaries.
**Typo.js** is written in *Typescript*.
## Node install
````txt
npm install --save typo-js-ts
````
## Usage
Type implements a Ready pattern that returns a [Promise](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise).
````javascript
var Typo = require('typo-js-ts').Typo;
var dict = new Typo("en_US");
dict.ready.then(()=>{
// Promise that dictionary is loaded
// do work
let spellSuggest = dict.suggest("speling");
console.log(spellSuggest);
// output [ "spelling", "spieling", "spewing", "peeling", "selling" ]
spellSuggest = dict.suggest("speling", 1);
console.log(spellSuggest);
// output: ["spelling"]
})
.catch((error) => {
// dictionary was not loaded
console.error(error);
});
````
or
````javascript
var Typo = require('typo-js-ts').Typo;
new Typo("en_US")
.ready.then(dictionary => {
// Promise that dictionary is loaded
// do worl
// test if mispelled is the corect spelling for en_US
console.log(dictionary.check("mispelled"));
})
.catch((error) => {
// dictionary was not loaded
console.error(error);
});
````
or using callback
````javascript
var Typo = require('typo-js-ts').Typo;
new Typo("en_US", null, null, {
loadedCallback: function (err, dict) {
if (err) {
console.error(err);
return;
}
let spellSuggest = dict.suggest("spitting");
console.log(spellSuggest);
// Correctly spelled words receive no suggestions.
// output [ ]
spellSuggest = dict.suggest("speling", 1);
console.log(dict.check("Alex")); // true
console.log(dict.check("alex")); // false
}
});
````
To use **Typo.js** in a Chrome extension, simply include the *typo.js* file in your extension's background page, and then initialize the dictionary like so:
```javascript
var Typo = require('typo-js-ts').Typo;
var dictionary = await new Typo("en_US").ready;
```
By default **Typo.js** looks for dictionaries to be in `typo/dictionaries` path.
The dictionary path for `us_US` would contain the following:
* `en_US/en_US.aff`
* `en_US/en_US.dic`
The default paths for `us_US` would be as follows:
* `typo/dictionaries/en_US/en_US.aff`
* `typo/dictionaries/en_US/en_US.dic`
if your dictionaries are stored in a different path then this can be pass to **Typo.js** by way of the settings.
```javascript
var Typo = require('typo-js-ts').Typo;
var dict = new Typo("en_US", null, null, {
dictionaryPath: "hunspell/dictionaries"
});
dict.ready.then(() => {
// Promise that dictionary is loaded
// do work
console.log(dict.check("1st")); // true
console.log(dict.check("1th")); // false
});
```
If using in node.js, load it like so:
```javascript
var Typo = require('typo-js-ts').Typo;
var dictionary = new Typo([...]);
```
Node as ES Module
````javascript
import { Typo } from "typo-js-ts";
var dictionary = new Typo([...]);
````
To check if a word is spelled correctly, do this:
```javascript
var is_spelled_correctly = dictionary.check("mispelled");
```
To get suggested corrections for a misspelled word, do this:
```javascript
var array_of_suggestions = dictionary.suggest("mispeling");
// array_of_suggestions == ["misspelling", "dispelling", "misdealing", "misfiling", "misruling"]
```
**Typo.js** has full support for the following Hunspell affix flags:
* PFX
* SFX
* REP
* FLAG
* COMPOUNDMIN
* COMPOUNDRULE
* ONLYINCOMPOUND
* KEEPCASE
* NOSUGGEST
* NEEDAFFIX
