npm - VS Code and tasks with node -

until used gulp building typescript , sass files, due couple of new build steps i'd unify , use node single entry point (also node running gulp tasks via npm run taskname).

tasks.json quite simple, task build should run npm run watch:

{     "version": "0.1.0",     "command": "npm",     "isshellcommand": true,     "tasks": [         {             "taskname": "build",             "isbuildcommand": true,             "showoutput": "always",             "iswatching": true,             "args": [                 "run", "watch"             ]         }     ] } 

package.json

"scripts": {     "watch": "gulp default", } 

and output:

gulp default build [14:20:54] using gulpfile path_to/gulpfile.js [14:20:54] task 'build' not in gulpfile [14:20:54] please check documentation proper gulpfile formatting npm err! windows_nt 6.3.9600 npm err! argv "c:\\program files (x86)\\nodejs\\\\node.exe" "c:\\program files (x86)\\nodejs\\node_modules\\npm\\bin\\npm-cli.js" "run" "watch" "build" npm err! node v0.12.2 npm err! npm  v2.7.4 npm err! code elifecycle npm err! 2@0.1.0 watch: `gulp default build` npm err! exit status 1 npm err!  npm err! failed @ 2@0.1.0 watch script 'gulp default build'. npm err! problem 2 package, npm err! not npm itself. npm err! tell author fails on system: npm err!     gulp default build npm err! can info via: npm err!     npm owner ls 2 npm err! there additional logging output above. npm err! please include following file support request: 

based on output, gulp still somehow used thought there no sign of in tasks.json (gulpfile.json exists in root directory , while searching solution found vs code auto detects it, assume might problem?). taskname property looks automatically appended command line argument wrong.

a smaller working example (but still runs gulp therefore typescript compiled twice on each save):

{     "version": "0.1.0",     "command": "npm",     "isshellcommand": true,     "args": [         "run", "watch"     ],     "showoutput": "always" } 

how can have multiple tasks in vs code through npm?

as mentioned in comments, if you're looking run npm scripts tasks vs code, this article instructs create .vscode\tasks.json following:

{     "version": "0.1.0",     "command": "npm",     "isshellcommand": true,     "suppresstaskname": true,     "tasks": [         {         // build task, ctrl+shift+b         // "npm install --loglevel info"         "taskname": "install",         "isbuildcommand": true,         "args": ["install", "--loglevel", "info"]         },         {         // test task, ctrl+shift+t         // "npm test"         "taskname": "test",         "istestcommand": true,         "args": ["test"]         },         {         // "npm run lint"         "taskname": "lint",         "args": ["run", "lint"]         }     ] } 

as alternative, there's sample vs code extension microsoft aimed @ detecting , running npm scripts items: vscode-npm-scripts
