[New Build System] Proposal for a new build system

[SergioRibera]

Current Context

The current Rust-based web services generator works through a CLI that executes commands for the build and the generation of a manifest according to the Solana Blinks standard. Services and endpoints are structured as libraries, and for each build, a new main.rs file is generated, copying all source code to a temporary folder. Although this system has been functional, it has important limitations, such as the need to copy all the source code for each build, resulting in heavy processes and loss of optimization, such as the cache of the target/ folder.

New Proposal

The proposal is to optimize the build system and generation of projects taking advantage of the generation macros that we currently have going from generating a library to generate a binary with a main function, this proposal allows us to preserve much of the infrastructure and allowing easily add the generation of the main function and what is required for each deployment system, in addition to making the deployment systems much more optimal and extensible, currently there is a conceptual test implementation that should be improved, can be reviewed in this file, for this the following tentative tasks are proposed with the possibility of adding more if it is seen convenient

• Workspaces are no longer necessary [New Build System] Moving workspaces to library files #108
• Check and fix the main generators [New Build System] Generate main function #109
• Modularize generation of main function [New Build System] Generate main function #109
• Migration command [New Build System] Migration command #110
• Test generation of main for Shuttle/Axum [New Build System] Update Examples and Tests #111
• Add more generators like AWS/GPC/Azure/etc (depends of [New Build System] Generate main function #109)
• Fix the current number of dependencies, there are now too many dependencies
