This is the README for the sqlite3 WASM/JS distribution. Main project page: https://sqlite.org Documentation: https://sqlite.org/wasm This archive contains the following deliverables for the WASM/JS build: - jswasm/sqlite3.js is the canonical "vanilla JS" version. - jswasm/sqlite3.mjs is the same but in ES6 module form - jswasm/*-bundler-friendly.js and .mjs are variants which are intended to be compatible with "bundler" tools commonly seen in node.js-based projects. Projects using such tools should use those variants, where available, instead of files without the "-bundler-friendly" suffix. Some files do not have separate variants. - jswasm/sqlite3.wasm is the binary WASM file imported by all of the above-listed JS files. - The jswasm directory additionally contains a number of supplemental JS files which cannot be bundled directly with the main JS files but are necessary for certain usages. - The top-level directory contains various demonstration and test applications for sqlite3.js and sqlite3.mjs. sqlite3-bundler-friendly.mjs requires client-side build tools to make use of and is not demonstrated here. Browsers will not serve WASM files from file:// URLs, so the test and demonstration apps require a web server and that server must include the following headers in its response when serving the files: Cross-Origin-Opener-Policy: same-origin Cross-Origin-Embedder-Policy: require-corp The core library will function without those headers but certain features, most notably OPFS storage, will not be available. One simple way to get the demo apps up and running on Unix-style systems is to install althttpd (https://sqlite.org/althttpd) and run: althttpd --enable-sab --page index.html
