tsbuild: A Reference Implementation for TypeScript Composite Project Build Orchestration

Installation

npm install -g @ryancavanaugh/tsbuild

Usage Examples

tsbuild

Recursively look for tsconfig.json files in the current directory and build all of them.

tsbuild --dry

Show what would be built.

tsbuild -p tsconfig_src.json -p tsconfig_tests.json

Build exactly these two projects.

Options

  --help       Show help                                  
  --version    Show version number                        
  --watch, -w  Watch mode                                 
  --dry, -d    Dry mode: Show what would be built and exit
  --force, -f  Force rebuild of all projects              
  --viz        Render a project dependency graph

Dogfooding Instructions

Installation

npm install -g @ryancavanaugh/tsbuild

Running

Once you've npm installed, you can run tsbuild from the commandline. See usage info above.

Language Service Dogfooding

This is a bit more involved. You can do the following:

git clone https://github.com/RyanCavanaugh/TypeScript.git
cd TypeScript
git checkout projectReferences
npm install
npm install -g jake
jake local

Once this is done, you can point VS Code's TypeScript install to the /built/local folder of the enlistment root:

    "typescript.tsdk": "C:/github/TypeScript/built/local/",
    "typescript.tsdk_version": "2.6.0",

Then select this version using the "TypeScript: Select TypeScript Version" command while a .ts file is open.

Setup

The main thing to do is to add a 'references' block to your tsconfig file:

    "references": [
      { "path": "../otherProj" }
    ]

Each element in the array points to a tsconfig file or a folder containing a file named tsconfig.json.

The demo repo https://github.com/RyanCavanaugh/project-references-demo-2 is a buildable example that uses project references to set up a dozen projects in a complex graph.

You'll also need to set { "composite": true } in any referenced tsconfig file.

Feedback

Please include the full version number (printed at the top of every invocation) with any bug reports. I'll be publishing updates to the NPM package as I fix things / add features, so you may want to run 'npm update -g @ryancavanaugh/tsbuild' every so often to pick up the latest build.

Changelog and Backlog

Upcoming work

Reduce I/O on tsconfig.json files - current implementation reads these from disk more than once per build
(TS) remove restriction on zero-input-file compilations
Figure out what to do with stripInternal
Figure out what to do with declaration bundling in prepend+outFile combinations

Release Log

0.1.5
- Implements pseduobuilds
  - A pseudobuild (PB) occurs when an upstream project is rebuilt but doesn't change its .d.ts. When this happens, downstream projects' outputs are 'touched' to the current time.
  - PBs are not enabled for outFile compilations because the output JS file still needs to be updated (TODO: we can allow this if there are no prepend references)
0.1.4
- Initial release
