Installation

npm install --save github:node-ffi-libraries/node-ffi-library-libjpeg-v9d#semver:^2.0.1

Example

const { load } = require("@ffi-libraries/libjpeg-v9d");

async function main() {
  // Lazy-loading the library and all dependencies.
  const library = await load();

  // A library might have more than one header file.
  console.dir(library);

  // Lazy-load an individual header file (random example, see output from above).
  const headerLoader = library.headers["./include/jconfig.h"];
  const header = await headerLoader();

  // You can now use the functions and types exported by the header file.
  console.dir(header);

  // Properly unload when done.
  await library.unload();
}

main();

Usage

• Used from Node.js (Javascript) to call the libjpeg dynamic library (C/C++).
  • No compilation required. All available binaries are included in the package and are loaded automatically.
  • Library header files are included, but most other documentation is not. See instead documentation for libjpeg.
• The header variable in the above example contains a Javascript object generated from the C/C++ header file.
  • C/C++ constants.
  • FFI typedefs.
  • Bindings to C/C++ functions.
• See the Node.js FFI tutorial to get started.
  • Using N-API (-napi) versions of FFI libraries is required.
  • See ffi-napi, ref-napi, and related -napi packages.
