I would check if a ZIP file is corrupted using NodeJS using less CPU and memory as possible.
How to corrupt a ZIP file:
I am trying to reach this goal using the NPM library "node-stream-zip"
private async assertZipFileIntegrity(path: string) {
try {
const zip = new StreamZip.async({ file: path });
const stm = await zip.stream(path);
stm.pipe(process.stdout);
stm.on('end', () => zip.close());
} catch (error) {
throw new Error();
}
}
However, when I run the unit tests I receive an error inside an array:
Rejected to value: [Error]
import zip from 'yauzl';
import path from 'path';
const invalidZipPath = path.resolve('invalid.zip');
const validZipPath = path.resolve('valid.zip');
const isValidZipFile = (filePath) => {
return zip.open(filePath, { lazyEntries: true }, (err, stream ) => {
if (err) {
console.log('fail to read ', filePath);
return false;
}
console.log('success read ', filePath);
return true;
});
}
isValidZipFile(validZipPath);
isValidZipFile(invalidZipPath);
