***A Gedcom file reader written in Typescript.*** See the **[documentation](https://docs.arbre.app/read-gedcom/)**.

### Features

* Tolerant parsing
  * Character encoding detection (ASCII, CP1252, UTF-8, UTF-16, CP850, and more)
  * Good effort of parsing and interpreting non-standard data
* Near full specification coverage
  * Mostly Gedcom 5.5.5 compliant while being as much backward compatible as possible
  * Parser for dates in any standard calendars
* Unopinionated API
  * We provide the API, but the user has full control over the interpretation of the data
  * It's also possible to not use the API, in which case it can be shaken off the tree
* Strongly typed
* Zero dependencies; compatible on browser and Node.js
  * Less than `20kB` gzipped
* ...and more:
  * Conversion of dates
  * Serialization-friendly
  * Progress tracking for larger files

### Installation and Usage

```
npm install read-gedcom
```


```javascript
import { readGedcom } from 'read-gedcom';

const promise = fetch('https://mon.arbre.app/gedcoms/royal92.ged')
  .then(r => r.arrayBuffer())
  .then(readGedcom);

promise.then(gedcom => {
  console.log(gedcom.getHeader().toString());
});
```

Or, if you simply want to include it as a javascript file, this is also possible:
```html
<script type="text/javascript" src="https://cdn.jsdelivr.net/npm/read-gedcom/dist/read-gedcom.min.js"></script>
<script>
    const promise = fetch('https://mon.arbre.app/gedcoms/royal92.ged')
            .then(r => r.arrayBuffer())
            .then(Gedcom.readGedcom);

    promise.then(gedcom => {
        console.log(gedcom.getHeader().toString());
    });
</script>
```
