Define multiple tasks in VSCode

Question

I have seen that it is possible to define a task in the VSCode. But I am not sure how to define multiple tasks in the tasks.json file.

Answer 1

Just in case it helps someone... . If you don't have/want gulp/grunt/etc... or an extra shell script to proxy out your task commands , "npm run" is there already .

this is for webpack and mocha as in "Build and Test" , Shift+Ctrl+B, Shift+Ctrl+T

.vscode/tasks.json:

{
  "name": "npmTask",
  //...
  "suppressTaskName": true,
  "command": "npm",
  "isShellCommand": true,
  "args": [
    "run"
  ],
  "tasks": [
    {
      //Build Task
      "taskName": "webpack",
      //Run On Shift+Ctrl+B
      "isBuildCommand": true,
      //Don't run when Shift+Ctrl+T
      "isTestCommand": false,
      // Show the output window if error any
      "showOutput": "silent",
      //Npm Task Name
      "args": [
        "webpack"
      ],
      // use 2 regex:
      // 1st the file, then the problem       
      "problemMatcher": {
        "owner": "webpack",
        "severity": "error",
        "fileLocation": "relative",
        "pattern": [
          {
            "regexp": "ERROR in (.*)",
            "file": 1
          },
          {
            "regexp": "\\((\\d+),(\\d+)\\):(.*)",
            "line": 1,
            "column": 2,
            "message": 3
          }
        ]
      }
    },
    {
      //Test Task   
      "taskName": "mocha",
      // Don't run on Shift+Ctrl+B
      "isBuildCommand": false,
      // Run on Shift+Ctrl+T
      "isTestCommand": true,
      "showOutput": "always",
      "args": [
        "mocha"
      ]
    }
  ]
}

package.json:

{
  ...
  "scripts": {
    "webpack": "webpack",
    "mocha": "/usr/bin/mocha"
  },
  ...
}
