Configuring VS Code's "tasks.json" file to compile all .ts files can be done by following these steps

Apologies if this question has been asked before, but could someone please redirect me to the relevant thread if so. I am wondering if it is possible to set up VS Code's "tasks.json" to automatically compile all .ts files within a folder. Currently, I am only able to manually add specific .ts files like this:

"args": [ HelloWorld.ts ],

While this works for compiling HelloWorld.ts, I am struggling to configure tasks.json in a way that compiles all .ts files in the directory.

I have followed tutorials suggesting to remove "HelloWorld.ts", but this does not result in any .ts files being compiled at all.

Below is my current tasks.json configuration in VS Code:

{
    "version": "0.1.0",

    // The command is tsc. Assumes that tsc has been installed using npm install -g typescript
    "command": "tsc",

    // The command is a shell script
    "isShellCommand": true,

    // Show the output window only if unrecognized errors occur.
    "showOutput": "always",

    // args is the HelloWorld program to compile.
    "args": [ "HelloWorld.ts" ],

    // use the standard tsc problem matcher to find compile problems
    // in the output.
    "problemMatcher": "$tsc"
}

Answer №1

To update your tasks.json file, delete the contents within the square brackets for the "args" key:

"args": []

Also, ensure that you have a tsconfig.json file present in your directory for successful compilation of all .ts files.

Answer №2

If you're looking to streamline your project, consider using gulp with VSCode support. Setting up tsconfig.json can help exclude unnecessary files, making it easier to manage what is needed for your large projects.

{ 
     "compilerOptions": { 
         "emitDecoratorMetadata": true, 
         "experimentalDecorators": true,
         "module": "commonjs", 
         "target": "es5",
         "sourceMap": true,
         "outDir": "dist",
         "declaration": true
     },
     "exclude": [
         "node_modules",
         "dist",
         ".vscode",
         "docs"
     ]
}

Your tasks.json configuration may look something like this:

{
    "version": "0.1.0",
    "command": "node",
    "windows": {
        "command": "node.exe"
    },
    "isShellCommand": true,
    "tasks": [
        {
            "taskName": "build-debug",
            "args": ["${workspaceRoot}/node_modules/gulp/bin/gulp.js", "build-debug"],
            "isBuildCommand": true,
            "suppressTaskName": true,
            "problemMatcher": [
                "$tsc"
            ]
        }
    ]
}

Utilize a local installation of gulp for optimal performance.

Here's an example gulpfile.js:

"use strict";

var gulp = require('gulp');
var ts = require('gulp-typescript');
var merge = require('merge2');
var sourcemaps = require('gulp-sourcemaps');
var del = require('del');

var tsProject = ts.createProject('tsconfig.json');

gulp.task('build-debug', function() {
    del.sync("dist");

    var tsResult = tsProject.src()
        .pipe(sourcemaps.init())   
    .pipe(ts(tsProject));

    return merge([
        tsResult.js
            .pipe(sourcemaps.write("./", { sourceRoot: __dirname }))
            .pipe(gulp.dest('dist')),
});

Don't forget to include the necessary dev dependencies in your package.json file:

  "devDependencies": {
    "gulp": "latest",
    "gulp-typescript": "latest",
    "gulp-sourcemaps": "latest",
    "merge2": "latest",
    "del": "latest"
  } 

Implementing these steps should enhance your workflow. Hope this information proves useful.

Answer №4

Create a _bundle.ts file, include links to all the necessary files for compilation, and then provide it as an argument to the args parameter.

This will generate a consolidated file with all the code transpiled together.

--==========================
  - Setting Up TypeScript Compiler in VS Code 
  - source : https://code.visualstudio.com/Docs/languages/typescript
--==========================
1/ Begin by creating a new file named "tsconfig.json"

        {
            "compilerOptions": {
                "target": "es5",
                "module": "commonjs",
                "sourceMap": true
            }
        }

2/ Next, create the tasks.json file: 
    - Press Ctrl+Shift+P and select Configure Task Runner.
    - Choose TypeScript - tsconfig.json.
    {
        // Refer to http://go.microsoft.com/fwlink/?LinkId=733558
        // for detailed documentation on the tasks.json format
        "version": "0.1.0",
        "command": "tsc",
        "isShellCommand": true,
        "args": ["-p", "."],
        "showOutput": "silent",
        "problemMatcher": "$tsc"
    }

3/ To run the Build Task, press Ctrl+Shift+B (Run Build Task)

Answer №6

@mishap's response touched on the key points, but one crucial detail was overlooked: there must be a blank space included in the "args" section like this:

"args": [ ]

instead of:

"args": []

Since these arguments are passed to the command/terminal running the tsc, it is essential to have a space within the "args" field in the tasks.json file.
