I have a powershell script and I run on powershell like :
.\download-packages-license.ps1
But I want to call the javascript file before these lines.
var json =fs.readFileSync('../../dev/licenses/AllLicenses.json', 'utf8');
var options = {compact: true, ignoreComment: true, spaces: 4};
var result = convert.json2xml(json, options);
I could not anything in stackoverflow except : How to run a powershell script from javascript? So pls help thanks
I think this will work for you -
var spawn = require("child_process").spawn;
spawn("powershell.exe",[".\download-packages-license.ps1"]);
You can work with : Node-Powershell
Code Snippet :
const Shell = require('node-powershell');
const ps = new Shell({
executionPolicy: 'Bypass',
noProfile: true
});
ps.addCommand('echo node-powershell');
ps.invoke()
.then(output => {
console.log(output);
})
.catch(err => {
console.log(err);
});
const ps = new Shell({ executionPolicy: 'Bypass', noProfile: true }); ps.addCommand('./download-packages-license.ps1'); but terminal work forever @Amit Baranes
JScript
Simple way.
Works great. Suitable for simple operations, but loses some data when receiving line feeds as a single \n instead of the expected \r\n. Split by \r\n misinterprets the array which leads to the need to reformat the array of strings. Basically, I just wrote this, so there may be other problems.
var codepage='windows-1251';/*US-Europe-1252 and Js file in that codepage*/
var toPStext='Hello.\nПроверка русских буковок.';
var shell=new ActiveXObject('WScript.Shell');
var std=shell.Exec("C:\\Windows\\System32\\WindowsPowerShell\\v1.0\\powershell.exe -ExecutionPolicy Bypass -command \
$OutputEncoding = [Console]::outputEncoding = [System.Text.Encoding]::GetEncoding('"+codepage+"'); \
Write-Output '"+toPStext+"'");
var output = std.StdOut.ReadAll().split('\r\n');// split('\n') - leads to the loss of some data
if (output.length>0){WScript.echo(output)}
//var x=WScript.StdIn.ReadLine();
Line by line.
Unfortunately, powershell does not accept external data as sequences of lines, unlike cmd.exe with /q /k options, which simplifies this code, but will turn around problems with multiline output code. Of course, if necessary, you can transfer the code as a base64 string to powershell
var codepage='windows-1251';/*US-Europe-1252 and Js file in that codepage*/
var toPStext='Hello.\nПроверка русских буковок.';
var shell=new ActiveXObject('WScript.Shell');
var output=[],errors=[],WshRunning=0,WshFinished=1,WshFailed=2,i=0,tryCount=0;
var std=shell.Exec("C:\\Windows\\System32\\WindowsPowerShell\\v1.0\\powershell.exe -ExecutionPolicy Bypass -command \
$OutputEncoding = [Console]::outputEncoding = [System.Text.Encoding]::GetEncoding('"+codepage+"'); \
Write-Output '"+toPStext+"'");
do{
if (std.Status==WshFailed){
errors.push('String '+i+' data read error: \n '+std.StdErr.ReadLine());
tryCount++
}
else if(std.Status==WshRunning){
output.push(std.StdOut.ReadLine());
tryCount=0;
WScript.Echo('Running ...')
}
else if(std.Status==WshFinished){
var last=std.StdOut.ReadLine();
if(last.length>0){output.push(last)};last=undefined;
tryCount=21;
WScript.Echo('Finished ...')
}i++;
}while(tryCount<21);
if (output.length>0){WScript.echo(output)}
if (errors.length>0){WScript.echo(errors)}
var x=WScript.StdIn.ReadLine();
