Question 1

How do I render text on a canvas with Typr.js?

Accepted Answer

Parse the font using Typr.parse(), shape the text with Typr.U.shape(), convert to a path via Typr.U.shapeToPath(), then draw it using Typr.U.pathToContext() on a Canvas 2D context. You'll need to manually apply transformations like scaling and translation.

Question 2

Typr.js vs opentype.js which should I choose?

Accepted Answer

Typr.js is lighter, faster, and has better font compatibility, but opentype.js offers more features and a higher-level API. Use Typr.js for performance-critical, low-level control; opentype.js for easier integration with richer utilities.

Question 3

Does Typr.js support Arabic text shaping out of the box?

Accepted Answer

No, basic shaping is limited. For advanced Arabic shaping, you must integrate HarfBuzz by loading a WASM file with Typr.U.initHB() and using Typr.U.shapeHB(), which adds setup complexity.

Question 4

How to extract glyph paths from a font file using Typr.js?

Accepted Answer

After parsing the font with Typr.parse(), use Typr.U.glyphToPath() with the glyph index to get a vector path in the custom format with cmds and crds arrays. This allows direct manipulation of outline data.

Question 5

Can Typr.js be used in Node.js for server-side processing?

Accepted Answer

Yes, Typr.js works in Node.js as it's pure JavaScript. You can parse font buffers and extract glyph data, but rendering to Canvas requires a compatible context, which might need additional libraries.

Question 6

What's the performance difference between Typr.js and other font libraries?

Accepted Answer

Typr.js is optimized for speed, with parsing 2-5x faster than opentype.js according to the README. However, rendering performance depends on your implementation, especially with complex paths or large text volumes.
