Roadmap 0.10, Performance roadmap — wave 3
PERF.26 Scale: text writers return one string, so exports stop at 512 MB and hold twice the output
DXF (dxf.js:1324, dxf2000.js:437), LandXML (landxml.js:227), OBJ, DAE, USDA (usda-write.js:33), GeoJSON and gcode writers each build one string and return it; a 1,000,000-entity DXF export is near the V8 string limit and the string plus its Blob is twice the output in memory. Change: writers that yield chunks into a WritableStream (createWritable on a file handle when the host offers one, else a Blob built from parts), with the same report object. Pairs with the streaming readers row.
