Snapshots allow the executable to startup fast. - -## `system_loader.js` - -This is a minimalistic implementation of a -[System](https://github.com/systemjs/systemjs) module loader. It is specifically -designed to load modules that are emitted from TypeScript the module format is -`"system"` and a single `"outfile"` is supplied, which is commonly refereed to -as a bundle. - -Because this loader becomes part of an emitted bundle under `Deno.bundle()` and -`deno bundle`, it has minimal comments and very terse and cryptic syntax, which -isn't very self documenting. Because of this, a guide to this file is provided -here. - -A bundle of System modules expects a `System.register()` function to be in scope -for registering the modules. Modules that are emitted from TypeScript in a -single out file always pass 3 arguments, the module specifier, an array of -strings of modules specifiers that this module depends upon, and finally a -module factory. - -The module factory requires two arguments to be passed, a function for exporting -values and a context object. We have to bind to some information in the -environment to provide these, so `gC` gets the context and `gE` gets the export -function to be passed to a factory. The context contains information like the -module specifier, a reference to the dynamic `import()` and the equivalent of -`import.meta`. The export function takes either two arguments of an named export -and its value, or an object record of keys of the named exports and the values -of the exports. - -Currently, TypeScript does not re-write dynamic imports which resolve to static -strings (see -[microsoft/TypeScript#37429](https://github.com/microsoft/TypeScript/issues/37429)), -which means the import specifier for a dynamic import which has been -incorporated in the bundle does not automatically match a module specifier that -has been registered in the bundle. The `di()` function provides the capability -to try to identify relative import specifiers and resolve them to a specifier -inside the bundle. If it does this, it resolves with the exports of the module, -otherwise it simply passes the module specifier to `import()` and returns the -resulting promise. - -The running of the factories is handled by `rF()`. When the factory is run, it -returns an object with two keys, `execute` and `setters`. `execute` is a -function which finalises that instantiation of the module, and `setters` which -is an array of functions that sets the value of the exports of the dependent -module. - -The `gExp()` and `gExpA()` are the recursive functions which returns the exports -of a given module. It will determine if the module has been fully initialized, -and if not, it will gather the exports of the dependencies, set those exports in -the module via the `setters` and run the modules `execute()`. It will then -always return or resolve with the exports of the module. - -As of TypeScript 3.8, top level await is supported when emitting ES or System -modules. When Deno creates a module bundle, it creates a valid, self-contained -ES module which exports the exports of the "main" module that was used when the -bundle was created. If a module in the bundle requires top-level-await, then the -`execute()` function is emitted as an async function, returning a promise. This -means that in order to export the values of the main module, the instantiation -needs to utilise top-level-await as well. - -At the time of this writing, while V8 and other JavaScript engines have -implemented top-level-await, no browsers have it implemented, meaning that most -browsers could not consume modules that require top-level-await. - -In order to allow more browsers to consume bundles, there is an argument that is -passed to the `__instantiate()` function which determines if the code is -bootstrapped asynchronously or not. When emitting a bundle that contains a -module that requires top-level-await, Deno will detect this and utilise -`await __instantiate(main, true)`. - -The `system_loader_es5.js` is a transpiled version of `system_loader.js` that is -designed to work with ES5 or later, and will be used when the bundle target is < -ES2017. While ES3 is still a potential target which can be passed in a -`tsconfig.json` to Deno, any resulting bundle will not be compatible, as there -is a need to utilise items like `Object.defineProperty()`. diff --git a/deno_typescript/lib.rs b/deno_typescript/lib.rs deleted file mode 100644 index f01993464..000000000 --- a/deno_typescript/lib.rs +++ /dev/null @@ -1,125 +0,0 @@ -// Copyright 2018-2020 the Deno authors.
