I have an array and i want to send it to a child process. But the problem is i get it in child process as a string. How can i fix it? Thanks.
parent file
const {fork} = require('child_process');
var botsList = [];
fork('./app.js', [botsList]);
child file:
var botsList = process.argv[2];
console.log(typeof botsList);
app.js will receive a string, but depending on the complexity of botsList, you could use JSON.stringify and JSON.parse
index.js will do something like:
const {fork} = require('child_process');
var botsList = ["botA", "botB", "botC"];
fork('./app.js', [JSON.stringify(botsList)]);
And app.js will do parsing of the argument:
let botsList = process.argv[2];
try {
botsList = JSON.parse(botsList);
} catch (e) {
console.log('Could not parse string as JSON');
}
console.log(botsList);
console.log(typeof botsList);
And the output:
