I'm trying to create a directory, then create a file in this directory, then I'm trying to delete the directory. If I'm running the functions one by one, the code is working, but when I'm running them together I get this error :
[Error: ENOENT: no such file or directory, open 'C:\Users\Andrei\Desktop\tw\test\test.txt'] { errno: -4058, code: 'ENOENT', syscall: 'open', path: 'C:\Users\Andrei\Desktop\tw\test\test.txt' }
Also if I'm running only the first 2 functions, everything works fine. What's wrong with my code?
const rimraf = require("rimraf");
const mkdirp = require("mkdirp");
const fs = require("fs");
const err1 = new Error("File Error!");
const err2 = new Error("Directory deleting Error!");
function createDirectory() {
mkdirp("./test");
}
function createFile() {
fs.writeFile("./test/test.txt", "this is my text", function (err1) {
if (err1) throw err1;
console.log("Results Received");
});
}
function deleteDirectory() {
rimraf("./test", function (err2) {
if (err2) console.log(err2);
console.log("Succesfully deleted a directory");
});
}
function main() {
createDirectory();
createFile();
deleteDirectory();
}
main();
Those functions are async. You'll need to use some Promise logic to make them chain:
const rimraf = require("rimraf");
const mkdirp = require("mkdirp");
const fs = require("fs");
const err1 = new Error("File Error!");
const err2 = new Error("Directory deleting Error!");
function createDirectory() {
return mkdirp("./test");
}
function createFile() {
return new Promise((resolve) => {
fs.writeFile("./test/test.txt", "this is my text", function (err1) {
if (err1) throw err1;
console.log("Results Received");
resolve();
});
});
}
function deleteDirectory() {
return new Promise((resolve) => {
rimraf("./test", function (err2) {
if (err2) console.log(err2);
console.log("Succesfully deleted a directory");
resolve();
});
});
}
function main() {
createDirectory()
.then(() => {
return createFile();
})
.then() => {
return deleteDirectory();
});
}
main();
mkdirp, writeFile, and rimraf ar all asynchronous, but you're not waiting for earlier ones to finish before you ask the later ones to start.
I'd suggest using an async functoin and the promise-enabled versions of those (mkdirp is already promise-enabled, use writeFile from fs/promises, and there has to be a promise wrapper for rimraf now; if not, use util.promisify). Then you could use await:
async function main() {
await createDirectory();
await createFile();
await deleteDirectory();
}
where (for example) createFile is:
const {writeFile} = require('fs/promises');
// ...
async function createFile() {
await writeFile("./test/test.txt", "this is my text");
console.log("Results Received");
}
