ttfmeta
A Node.js module and a library that extracted metadata from ttf font file or buffer. It is forked from trevordixon/ttfinfo and improve, add test. Check live Demo using Vue is available...
Feature
- [x] has TypeScript declarations
- [x] support both ESM and CommonJS including browser
- [x] Reading from file (or) buffer
- [x] Demo
Usage
Node.JS
Oops:
ttfmeta
export ES module from CommonJS built version.
export * from "./index.js";
import * as e from "./index.js";
export default e;
npm i ttfmeta
can be require
or import
from your Node.JS application. However ttfmeta
is assuming that one day npm might force us to seperate ES module and CommonJS. Therefore, it is a good practice to start coding Node.JS application using ES module.
// ES6
import ttfMeta from 'ttfmeta';
import {ttfInfo,promise} from 'ttfmeta';
// CommonJS
const ttfMeta = require('ttfmeta');
const {ttfInfo,promise} = require('ttfmeta');
Browser
Include the file ttfmeta@latest/min.js
in your web application. It is available on UNPKG and jsDelivr.
Now let's assume that you have picked the jsDelivr one...
<script src="https://cdn.jsdelivr.net/npm/ttfmeta@latest/min.js"></script>
<input type="file" name="files[]" multiple />
<script>
// window.ttfMeta;
var file = 'blob or arrayBuffer';
var reader = new FileReader();
reader.onload = function(evt) {
var arrayBuffer = evt.target.result;
var data = new DataView(arrayBuffer, 0, arrayBuffer.byteLength);
window.ttfMeta.promise(data).then(
e => console.log(e)
).catch(
e=>console.log('error',e)
)
}
reader.readAsArrayBuffer(file);
</script>
API
You may assure that the APIs are not going to change without a good reason for end user. So any exported methods
and classes
name will stays the same as the last updates.
Promise
the ttfMeta.promise()
, promise()
ttfMeta.promise('file.ttf').then(
result => console.log(result)
).catch(
err => console.log('error',err)
);
// or
promise('file.ttf (or) buffer').then(
result => console.log(result)
).catch(
err => console.log('error',err)
);
ttfInfo
the ttfMeta.ttfInfo()
, ttfInfo()
ttfMeta.ttfInfo('file.ttf', (err, result) => {
if (err) {
console.log('error', err)
} else {
console.log('result', result)
}
});
// or
ttfInfo('file.ttf (or) buffer', (err, result) => ...);
Result
This result promise an object with meta
and tables
regardless.
