pushing changes to git using node

I'm trying to commit and push changes using node without using any external npm packages
const { spawn,exec } = require('child_process');
const fs = require('fs');
const { stderr } = require('process');
(async ()=>{
if(fs.existsSync('./repo_dir'))
fs.rmSync('./repo_dir',{recursive:true});
exec(`git config --global --replace-all user.name "NAMEHERE" && git config --global --replace-all user.email "EMAIL#gmail.com" && git config --list`,(err,stdout,stderr)=>{
if(err)
console.log(`error: ${err}`);
if(stderr)
console.log(`stderr: ${stderr}`);
console.log(`stdout: ${stdout}`);
let git_spawn=spawn(`git`,[`clone`,`https://username:token#github.com/username/repo_dir.git`]);
git_spawn.stdout.on("data", data => {
console.log(`cloning stdout: ${data}`);
});
git_spawn.stderr.on("data", data => {
console.log(`cloning stderr: ${data}`);
});
git_spawn.on('error', (error) => {
console.log(`cloning error: ${error.message}`);
});
git_spawn.on("close", code => {
console.log(`child process exited with code ${code}`);
exec(`cd ./git_repo && touch blank.js && git add -A && git commit -m "updating" && git push && cd ..`,(err,stdout,stderr)=>{ //error somewhere here
console.log(`pushing error: ${err}`);
console.log(`pushing stdout: ${stdout}`);
console.log(`pushing stderr: ${stderr}`);
});
});
})
})();
but for some reason it doesn't work and I can't even pin point the error
output:
stdout: cloning stderr: Cloning into 'repo_dir'...
child process exited with code 0 pushing error: Error: Command failed:
cd ./repo_dir && touch blank.js && git add -A && git commit -m
"updating" && git push && cd ..
pushing stdout: On branch main Your branch is up to date with
'origin/main'.
nothing to commit, working tree clean
pushing stderr:
I'm guessing the problem is somewhere in committing and pushing

How to run a jar file in javascript and have it return a json

I have a jar file that returns a json. How can I run it and take the output through javascript?

There is a no browser side java compiler i guess, so you must use javascript on the backend side, i suggest use nodejs
const { exec } = require('child_process');
exec('java -jar /file/to/path.jar',(error, stdout, stderr) => {
console.log(stdout);
console.log(stderr);
if (error !== null) {
console.log(`exec error: ${error}`);
}
});

'sed' Command doesn't work with java script

I want to exectue following Shell Command with the Execute Option form Javascript:
"sed -i 4r<(sed '1,5!d' /etc/wpa_supplicant/wpa_template.template) /etc/wpa_supplicant/wpa_supplicant.conf"
Then i try this command in the shell console it works perfektly. But after starting it with the .js programm nothing is happen. I just want to copy the first 5 lines in template and add them to the config file.

You can do with exec from child_process
const exec = require('child_process').exec
exec("sed -i 4r<(sed '1,5!d' /etc/wpa_supplicant/wpa_template.template) /etc/wpa_supplicant/wpa_supplicant.conf", (err, stdout, stderr) => {
if (err) {
return console.error(err)
}
console.log(`stdout: ${stdout}`)
console.log(`stderr: ${stderr}`)
})

You can use the below code to execute any shell command and replace the o/p to a new file(create a new file) everytime you run it. And, you should use the line-reader module to get the line from the files.
npm install --save line-reader
const fs = require('fs');
const lineReader = require('line-reader');
const { exec } = require('child_process');
const cmd = "sed -i 4r<(sed '1,5!d' /etc/wpa_supplicant/wpa_template.template) /etc/wpa_supplicant/wpa_supplicant.conf"
exec(cmd, (err, stdout, stderr) => {
if (err) {
//some err occurred
console.error(err)
} else {
// the *entire* stdout and stderr (buffered)
fs.writeFile('file path', stdout, (err) => {
// throws an error, you could also catch it here
if (err) throw err;
// success case, the file was saved
console.log('file saved');
readFile1();
});
}
});
const readFile1 = () => lineReader.eachLine('file path', function(line) {
//make logic to take number of lines you want to take.
console.log(line);
});

LSOpenURLsWithRole() failed for the application /location/name.app with error -10810

I'm trying to open application using nodejs (I'd like this process to be workable in cross-platform , MAC/Windows ..etc
here's the code
const { exec } = require('child_process')
const fs = require('fs')
// giving the required permissions , not really sure if 777 is the right choice
fs.chmodSync(appPath,777);
exec("open -a " + path , (err, stdout, stderr) => {
console.log(err);
console.log(stdout);
console.log(stderr);
});
console.log(err); // logs this error
{ Error: Command failed: open -a /location.app
LSOpenURLsWithRole() failed for the application /location.app with error -10810
when executing the same command in terminal (out of node) , it fires the same issue

Run an installer inside my program

How can I run an installer of an independent program (exe file) from inside of my code?
The idea in general is program which install other programs.
Thanks!

use exec of node.js
const { exec } = require('child_process');
exec('path/to/exe', (error, stdout, stderr) => {
if (error) {
console.error(`exec error: ${error}`);
return;
}
console.log(`stdout: ${stdout}`);
console.log(`stderr: ${stderr}`);
});
