//! # [`BuildRequest`] - the core of the build process
|
|
//!
|
|
//! The [`BuildRequest`] object is the core of the build process. It contains all the resolved arguments
|
|
//! flowing in from the CLI, dioxus.toml, env vars, and the workspace.
|
|
//!
|
|
//! Every BuildRequest is tied to a given workspace and BuildArgs. For simplicity's sake, the BuildArgs
|
|
//! struct is used to represent the CLI arguments and all other configuration is basically just
|
|
//! extra CLI arguments, but in a configuration format.
|
|
//!
|
|
//! When [`BuildRequest::build`] is called, it will prepare its work directory in the target folder
|
|
//! and then start running the build process. A [`BuildContext`] is required to customize this
|
|
//! build process, containing a channel for progress updates and the build mode.
|
|
//!
|
|
//! The [`BuildMode`] is extremely important since it influences how the build is performed. Most
|
|
//! "normal" builds just use [`BuildMode::Base`], but we also support [`BuildMode::Fat`] and
|
|
//! [`BuildMode::Thin`]. These builds are used together to power the hot-patching and fast-linking
|
|
//! engine.
|
|
//! - BuildMode::Base: A normal build generated using `cargo rustc`
|
|
//! - BuildMode::Fat: A "fat" build where all dependency rlibs are merged into a static library
|
|
//! - BuildMode::Thin: A "thin" build that dynamically links against the artifacts produced by the "fat" build
|
|
//!
|
|
//! The BuildRequest is also responsible for writing the final build artifacts to disk. This includes
|
|
//!
|
|
//! - Writing the executable
|
|
//! - Processing assets from the artifact
|
|
//! - Writing any metadata or configuration files (Info.plist, AndroidManifest.xml)
|
|
//! - Bundle splitting (for wasm) and wasm-bindgen
|
|
//!
|
|
//! In some cases, the BuildRequest also handles the linking of the final executable. Specifically,
|
|
//! - For Android, we use `dx` as an opaque linker to dynamically find the true android linker
|
|
//! - For hotpatching, the CLI manually links the final executable with a stub file
|
|
//!
|
|
//! ## Build formats:
|
|
//!
|
|
//! We support building for the most popular platforms:
|
|
//! - Web via wasm-bindgen
|
|
//! - macOS via app-bundle
|
|
//! - iOS via app-bundle
|
|
//! - Android via gradle
|
|
//! - Linux via app-image
|
|
//! - Windows via exe, msi/msix
|
|
//!
|
|
//! Note that we are missing some setups that we *should* support:
|
|
//! - PWAs, WebWorkers, ServiceWorkers
|
|
//! - Web Extensions
|
|
//! - Linux via flatpak/snap
|
|
//!
|
|
//! There are some less popular formats that we might want to support eventually:
|
|
//! - TVOS, watchOS
|
|
//! - OpenHarmony
|
|
//!
|
|
//! Also, some deploy platforms have their own bespoke formats:
|
|
//! - Cloudflare workers
|
|
//! - AWS Lambda
|
|
//!
|
|
//! Currently, we defer most of our deploy-based bundling to Tauri bundle, though we should migrate
|
|
//! to just bundling everything ourselves. This would require us to implement code-signing which
|
|
//! is a bit of a pain, but fortunately a solved process (<https://github.com/rust-mobile/xbuild>).
|
|
//!
|
|
//! ## Build Structure
|
|
//!
|
|
//! Builds generally follow the same structure everywhere:
|
|
//! - A main executable
|
|
//! - Sidecars (alternate entrypoints, framewrok plugins, etc)
|
|
//! - Assets (images, fonts, etc)
|
|
//! - Metadata (Info.plist, AndroidManifest.xml)
|
|
//! - Glue code (java, kotlin, javascript etc)
|
|
//! - Entitlements for code-signing and verification
|
|
//!
|
|
//! We need to be careful to not try and put a "round peg in a square hole," but most platforms follow
|
|
//! the same pattern.
|
|
//!
|
|
//! As such, we try to assemble a build directory that's somewhat sensible:
|
|
//! - A main "staging" dir for a given app
|
|
//! - Per-profile dirs (debug/release)
|
|
//! - A platform dir (ie web/desktop/android/ios)
|
|
//! - The "bundle" dir which is basically the `.app` format or `wwww` dir.
|
|
//! - The "executable" dir where the main exe is housed
|
|
//! - The "assets" dir where the assets are housed
|
|
//! - The "meta" dir where stuff like Info.plist, AndroidManifest.xml, etc are housed
|
|
//!
|
|
//! There's also some "quirky" folders that need to be stable between builds but don't influence the
|
|
//! bundle itself:
|
|
//! - session_cache_dir which stores stuff like window position
|
|
//!
|
|
//! ### Web:
|
|
//!
|
|
//! Create a folder that is somewhat similar to an app-image (exe + asset)
|
|
//! The server is dropped into the `web` folder, even if there's no `public` folder.
|
|
//! If there's no server (SPA), we still use the `web` folder, but it only contains the
|
|
//! public folder.
|
|
//!
|
|
//! ```
|
|
//! web/
|
|
//! server
|
|
//! assets/
|
|
//! public/
|
|
//! index.html
|
|
//! wasm/
|
|
//! app.wasm
|
|
//! glue.js
|
|
//! snippets/
|
|
//! ...
|
|
//! assets/
|
|
//! logo.png
|
|
//! ```
|
|
//!
|
|
//! ### Linux:
|
|
//!
|
|
//! <https://docs.appimage.org/reference/appdir.html#ref-appdir>
|
|
//! current_exe.join("Assets")
|
|
//! ```
|
|
//! app.appimage/
|
|
//! AppRun
|
|
//! app.desktop
|
|
//! package.json
|
|
//! assets/
|
|
//! logo.png
|
|
//! ```
|
|
//!
|
|
//! ### Macos
|
|
//!
|
|
//! We simply use the macos format where binaries are in `Contents/MacOS` and assets are in `Contents/Resources`
|
|
//! We put assets in an assets dir such that it generally matches every other platform and we can
|
|
//! output `/assets/blah` from manganis.
|
|
//! ```
|
|
//! App.app/
|
|
//! Contents/
|
|
//! Info.plist
|
|
//! MacOS/
|
|
//! Frameworks/
|
|
//! Resources/
|
|
//! assets/
|
|
//! blah.icns
|
|
//! blah.png
|
|
//! CodeResources
|
|
//! _CodeSignature/
|
|
//! ```
|
|
//!
|
|
//! ### iOS
|
|
//!
|
|
//! Not the same as mac! ios apps are a bit "flattened" in comparison. simpler format, presumably
|
|
//! since most ios apps don't ship frameworks/plugins and such.
|
|
//!
|
|
//! todo(jon): include the signing and entitlements in this format diagram.
|
|
//! ```
|
|
//! App.app/
|
|
//! main
|
|
//! assets/
|
|
//! ```
|
|
//!
|
|
//! ### Android:
|
|
//!
|
|
//! Currently we need to generate a `src` type structure, not a pre-packaged apk structure, since
|
|
//! we need to compile kotlin and java. This pushes us into using gradle and following a structure
|
|
//! similar to that of cargo mobile2. Eventually I'd like to slim this down (drop buildSrc) and
|
|
//! drive the kotlin build ourselves. This would let us drop gradle (yay! no plugins!) but requires
|
|
//! us to manage dependencies (like kotlinc) ourselves (yuck!).
|
|
//!
|
|
//! <https://github.com/WanghongLin/miscellaneous/blob/master/tools/build-apk-manually.sh>
|
|
//!
|
|
//! Unfortunately, it seems that while we can drop the `android` build plugin, we still will need
|
|
//! gradle since kotlin is basically gradle-only.
|
|
//!
|
|
//! Pre-build:
|
|
//! ```
|
|
//! app.apk/
|
|
//! .gradle
|
|
//! app/
|
|
//! src/
|
|
//! main/
|
|
//! assets/
|
|
//! jniLibs/
|
|
//! java/
|
|
//! kotlin/
|
|
//! res/
|
|
//! AndroidManifest.xml
|
|
//! build.gradle.kts
|
|
//! proguard-rules.pro
|
|
//! buildSrc/
|
|
//! build.gradle.kts
|
|
//! src/
|
|
//! main/
|
|
//! kotlin/
|
|
//! BuildTask.kt
|
|
//! build.gradle.kts
|
|
//! gradle.properties
|
|
//! gradlew
|
|
//! gradlew.bat
|
|
//! settings.gradle
|
|
//! ```
|
|
//!
|
|
//! Final build:
|
|
//! ```
|
|
//! app.apk/
|
|
//! AndroidManifest.xml
|
|
//! classes.dex
|
|
//! assets/
|
|
//! logo.png
|
|
//! lib/
|
|
//! armeabi-v7a/
|
|
//! libmyapp.so
|
|
//! arm64-v8a/
|
|
//! libmyapp.so
|
|
//! ```
|
|
//! Notice that we *could* feasibly build this ourselves :)
|
|
//!
|
|
//! ### Windows:
|
|
//! <https://superuser.com/questions/749447/creating-a-single-file-executable-from-a-directory-in-windows>
|
|
//! Windows does not provide an AppImage format, so instead we're going build the same folder
|
|
//! structure as an AppImage, but when distributing, we'll create a .exe that embeds the resources
|
|
//! as an embedded .zip file. When the app runs, it will implicitly unzip its resources into the
|
|
//! Program Files folder. Any subsequent launches of the parent .exe will simply call the AppRun.exe
|
|
//! entrypoint in the associated Program Files folder.
|
|
//!
|
|
//! This is, in essence, the same as an installer, so we might eventually just support something like msi/msix
|
|
//! which functionally do the same thing but with a sleeker UI.
|
|
//!
|
|
//! This means no installers are required and we can bake an updater into the host exe.
|
|
//!
|
|
//! ## Handling asset lookups:
|
|
//! current_exe.join("assets")
|
|
//! ```
|
|
//! app.appimage/
|
|
//! main.exe
|
|
//! main.desktop
|
|
//! package.json
|
|
//! assets/
|
|
//! logo.png
|
|
//! ```
|
|
//!
|
|
//! Since we support just a few locations, we could just search for the first that exists
|
|
//! - usr
|
|
//! - ../Resources
|
|
//! - assets
|
|
//! - Assets
|
|
//! - $cwd/assets
|
|
//!
|
|
//! ```
|
|
//! assets::root() ->
|
|
//! mac -> ../Resources/
|
|
//! ios -> ../Resources/
|
|
//! android -> assets/
|
|
//! server -> assets/
|
|
//! liveview -> assets/
|
|
//! web -> /assets/
|
|
//! root().join(bundled)
|
|
//! ```
|
|
//!
|
|
//! Every dioxus app can have an optional server executable which will influence the final bundle.
|
|
//! This is built in parallel with the app executable during the `build` phase and the progres/status
|
|
//! of the build is aggregated.
|
|
//!
|
|
//! The server will *always* be dropped into the `web` folder since it is considered "web" in nature,
|
|
//! and will likely need to be combined with the public dir to be useful.
|
|
//!
|
|
//! We do our best to assemble read-to-go bundles here, such that the "bundle" step for each platform
|
|
//! can just use the build dir
|
|
//!
|
|
//! When we write the AppBundle to a folder, it'll contain each bundle for each platform under the app's name:
|
|
//! ```
|
|
//! dog-app/
|
|
//! build/
|
|
//! web/
|
|
//! server.exe
|
|
//! assets/
|
|
//! some-secret-asset.txt (a server-side asset)
|
|
//! public/
|
|
//! index.html
|
|
//! assets/
|
|
//! logo.png
|
|
//! desktop/
|
|
//! App.app
|
|
//! App.appimage
|
|
//! App.exe
|
|
//! server/
|
|
//! server
|
|
//! assets/
|
|
//! some-secret-asset.txt (a server-side asset)
|
|
//! ios/
|
|
//! App.app
|
|
//! App.ipa
|
|
//! android/
|
|
//! App.apk
|
|
//! bundle/
|
|
//! build.json
|
|
//! Desktop.app
|
|
//! Mobile_x64.ipa
|
|
//! Mobile_arm64.ipa
|
|
//! Mobile_rosetta.ipa
|
|
//! web.appimage
|
|
//! web/
|
|
//! server.exe
|
|
//! assets/
|
|
//! some-secret-asset.txt
|
|
//! public/
|
|
//! index.html
|
|
//! assets/
|
|
//! logo.png
|
|
//! style.css
|
|
//! ```
|
|
//!
|
|
//! When deploying, the build.json file will provide all the metadata that dx-deploy will use to
|
|
//! push the app to stores, set up infra, manage versions, etc.
|
|
//!
|
|
//! The format of each build will follow the name plus some metadata such that when distributing you
|
|
//! can easily trim off the metadata.
|
|
//!
|
|
//! The idea here is that we can run any of the programs in the same way that they're deployed.
