tsc-run-scripts-hook

This is a package that will run configured npm scripts after tsc is run. It will even follow project references in your tsconfig.json to run their scripts.

when does this run

We only run scripts under the following conditions:

• the args aren't present: -h, --help, -all, --clean
• and if the tsc process exits successfully (0)

The npm scripts will be run as the tsc process exits.

examples

copy files

Say you want to be able to copy all non-{ts,js} files after typescript builds. You would use the following tsconfig.json:

tsconfig.json

{
  "compilerOptions": { ... },
  "run-scripts": ["build-step:copy-files"]
}

package.json

{
  "scripts": {
    "build-step:copy-files": "copyfiles -u 1 src/**/*.{json,html} dist/",
  },
  ...
  "devDependencies": {
    "copyfiles": "*",
  }
}

This would be equivalent to the following when running $ tsc ....

$ tsc [-b] # or whatever you use to build
$ npm run build-step:copy-files
| $ copyfiles ...

copy files with project references

Say you want to be able to copy all non-{ts,js} files after typescript builds and you had more than one project in your repo that you defined using tsconfig.json's references field. You would use the following layout:

project-a/tsconfig.json

{
  "compilerOptions": { ... },
  "run-scripts": ["build-step:copy-files"],
  "references": [
    { "path": "project-b" }
  ]
}

project-a/package.json

{
  "scripts": {
    "build-step:copy-files": "copyfiles -u 1 src/**/*.{json,html} dist/",
  },
  ...
}

project-b/tsconfig.json

{
  "compilerOptions": { ... },
  "run-scripts": ["build-step:copy-files"]
}

project-b/package.json

{
  "scripts": {
    "build-step:copy-files": "copyfiles -u 1 src/**/*.{json,html} dist/",
  },
  ...
}

This would be equivalent to the following when running $ tsc ....

[project-a] $ tsc -b
[project-b] $ npm run build-step:copy-files
[project-b] | $ copyfiles ...
[project-a] $ npm run build-step:copy-files
[project-a] | $ copyfiles ...

tsconfig.json: project references

This is particularly helpful in situations with a monorepo and configured tsconfig project references. By default without this project, it will compile the references, but not run scripts! This is where tsc-run-scripts-hook comes in handy. It's a lightweight project meant to run npm scripts post build.
