// We are modularizing this manually because the current modularize setting in Emscripten has some issues:
|
|
// https://github.com/kripken/emscripten/issues/5820
|
|
// In addition, When you use emcc's modularization, it still expects to export a global object called `Module`,
|
|
// which is able to be used/called before the WASM is loaded.
|
|
// The modularization below exports a promise that loads and resolves to the actual sql.js module.
|
|
// That way, this module can't be used before the WASM is finished loading.
|
|
|
|
// We are going to define a function that a user will call to start loading initializing our Sql.js library
|
|
// However, that function might be called multiple times, and on subsequent calls, we don't actually want it to instantiate a new instance of the Module
|
|
// Instead, we want to return the previously loaded module
|
|
|

// TODO: Make this not declare a global if used in the browser

// (Note that this is lowercase `module`)
|
|
// if (typeof module !== 'undefined') {
|
|
// module['exports'] = Module;
|
|
// }
|
|
// When that runs, it's going to overwrite our own modularization export efforts in shell-post.js!
|
|
// The only way to tell emcc not to emit it is to pass the MODULARIZE=1 or MODULARIZE_INSTANCE=1 flags,
|
|
// but that carries with it additional unnecessary baggage/bugs we don't want either.
|
|
// So, we have three options:
|
|
// 1) We undefine `module`
|
|
// 2) We remember what `module['exports']` was at the beginning of this function and we restore it later
|
|
// 3) We write a script to remove those lines of code as part of the Make process.
|
|
//
|
|
// Since those are the only lines of code that care about module, we will undefine it. It's the most straightforward
|
|
// of the options, and has the side effect of reducing emcc's efforts to modify the module if its output were to change in the future.
|
|
// That's a nice side effect since we're handling the modularization efforts ourselves
