downloaded file has extension .gi instead of .gif

[alwex]

this is due to the default maxLength option from the module used to sanitise filename on save: https://github.com/sindresorhus/filenamify#maxlength

if the filename is longer than 100 characters, the module will truncate it. download does not seems to have options to update this default behaviour.

You can use this simple snippet as a replacement:

const fs = require('fs')
const https = require('https')

async function download(url, targetFile) {
    return new Promise((resolve, reject) => {
        https
            .get(url, (response) => {
                const code = response.statusCode ?? 0

                if (code >= 400) {
                    return reject(new Error(response.statusMessage))
                }

                const fileWriter = fs
                    .createWriteStream(targetFile)
                    .on('finish', () => {
                        resolve({})
                    })

                response.pipe(fileWriter)
            })
            .on('error', (error) => {
                reject(error)
            })
    })
}

await download('http://mywebsite.com/path/to/remotefile.gif', `${__dirname}/out/remotefile.gif`)
