Running NPM scripts sequentially

Question

Let's say I have

"scripts": {
    "pre-build": "echo \"Welcome\" && exit 1",
    "build_logic": "start cmd.exe @cmd /k \"yo esri-appbuilder-js:widget && exit 1\"",
    "post_build":  "start C:\\WebAppBuilderForArcGIS\\startupShortcut",
    "exit" : "start cmd.exe @cmd /k \"echo \"goodbye\" && exit 1\""
  },

What NPM command can I run to let all of these scripts launch sequentially. When I use pre/post fixing they launch sequentially but they don't wait for the parent script to finish before executing. I am assuming the only solution is like: How do I get Gulp tasks to fire sequentially when firing shell commands in an async.series helper function? ? I know this can be done with Gulp but I would like to stick with NPM for now to explore its capabilities. Thanks for any help!

Answer 1

Invoke these scripts via npm run and chain them with double ampersand &&:

npm run pre-build && npm run build_logic && npm run post_build && npm run exit

Explanation:

• Use && (double ampersand) for sequential execution.
• Use & (single ampersand) for parallel execution.
