Programmatically install/uninstall npm dependencies by spawning a npm
child process.
var install = require('spawn-npm-install')
install(['through2', 'quote-stream'], { saveDev: true }, function(err) {
if (err)
console.error("Could not install:\n" + err.message)
else
console.log("Installed.")
})
Returns the child process, so you can print install log/warnings like so:
var proc = install('tape')
proc.stderr.pipe(process.stderr)
proc.stdout.pipe(process.stdout)
Or, to preserve log output and colors:
install('tape', { stdio: 'inherit' })
PRs welcome.
Spawns an npm install
using the given dependencies
(string or array of strings). You can pass opt
to the command, which will convert camel case to dash-case for the CLI arguments. The last parameter cb
is the callback which is passed (err)
on failure, or null otherwise.
You can specify a command
for options to use instead of the default npm
(e.g. for specialized analytics or other hooks).
Also accepts some options for the child process:
-
env
environment variables -
stdio
the standard err/out -
cwd
the current working directory
Returns the child process.
Examples:
var install = require('spawn-npm-install')
install('tape', { saveDev: true }, done)
install(['zalgo', 'img'], function(err) {
if (err)
console.error(err.message)
})
The default export spawn
is the same as spawn.install
, for symmetry.
The same as above, but triggers npm uninstall
instead.
