I read all those below, but it is still for me impossible to do it. Too hard for many people like me. Can you provide a guide or document details how to include FTS3 and spatialite extension? a step by step guide will make us easier. Or simple just provide a final build result and published it here for download, that will be great! Look for "load extension", "FTS3", "spatialite" in the existing issues: https://github.com/sql-js/sql.js/issues/68 https://github.com/sql-js/sql.js/issues/89 https://github.com/sql-js/sql.js/issues/316#issuecomment-569073185 https://github.com/sql-js/sql.js/issues/342#issuecomment-587336036 _Originally posted by @frafra in https://github.com/sql-js/sql.js/issues/390#issuecomment-623519922_
