How to call one command from another in package.json?

Question

suppose if i have some script in package.json like this

 "scripts": {     "a1": "first command",     "a2": "second command",     "a3": "third command",          } 

and if i want to run script a1 and a2 in the script a3 how can i do this? can this be possible? I am using

node version : v6.9.4

npm version : 4.3.0

i want to achieve something like this

"scripts": {     "a1": "first command",     "a2": "second command",     "a3": "third command && a1 && a2",          } 

Answer 1

Use npm run inside the script. E.g.

"scripts": {   "a1": "first command",   "a2": "second command",   "a3": "third command && npm run a1 && npm run a2", } 

Running $ npm run a3 via the CLI will run the third command (whatever that is), followed by a1, then a2.

However, if running $npm run a3 via the CLI is to only run a1 followed by a2 then:

"scripts": {   "a1": "first command",   "a2": "second command",   "a3": "npm run a1 && npm run a2", }
