What happened

page.text() of @lamina/pdf was called on a page of a document opened in the base module, which has no text extraction.

Why

@lamina/pdf ships three WebAssembly modules (ADR 0016 §4): base (open, read, edit, save), extract (base plus text extraction) and text (base plus fonts, shaping and extraction). A document lives in the module it was opened in, and opening uses the richest one loaded at that moment: text, then extract, then base. A document opened before the extract or text module was loaded stays in the base module.

How to fix

Load the extract module (about half the size of the text module) before opening the document: await init({ extract: true }) or await loadExtract(). A document already open in the base module can be moved by saving it and opening the bytes again.

Example

await init();
const doc = Document.open(bytes);
doc.page(0).text(); // throws { code: "extract-module-not-loaded", … }


await loadExtract();
Document.open(bytes).page(0).text().text(); // works
