Example

import fs from 'fs'
import WDwloadDlp from './src/WDwloadDlp.mjs'

    //fp
    let fp = './test.mp4'

    //funProg
    let funProg = (prog, nn, na) => {
        console.log('prog', `${prog.toFixed(2)}%`, nn, na)
    }

    //WDwloadDlp
    await WDwloadDlp(url, fp, {
        clean: true, //單一程序執行時, 事先清除之前暫存檔, 減少浪費硬碟空間
        funProg,
    })

    //len
    let len = fs.statSync(fp).size
    console.log('len', len)

    console.log('done:', fp)
}
test()
    .catch((err) => {
        console.log('catch', err)
    })
// prog 0.49% 1 99

Type

Promise

(async) autoDownloadFiles() → {Promise}

Description:

• 自動定位yt-dlp.exe與ffmpeg.exe，若無檔案則自動下載，回傳各執行檔的絕對路徑

  yt-dlp.exe依序偵測當前工作路徑的yt-dlp/與node_modules/w-dwload-dlp/yt-dlp/，皆無時， 代表安裝時npm封鎖scripts致postinstall未執行，故自動調用downloadFiles重新下載

  ffmpeg.exe由w-ffmpeg之autoDownloadFiles負責偵測與下載，故基於本套件開發之套件或專案， 僅須調用本函數即可備齊全部執行檔，無須各自再調用w-ffmpeg之autoDownloadFiles

  供w-dwload-dlp自身與其他依賴w-dwload-dlp的套件調用，無須各自實作偵測與下載邏輯

  因yt-dlp.exe與ffmpeg.exe只能用於Windows作業系統，故調用前須自行檢核作業系統

• autoDownloadFiles.mjs, line 50

Example

import autoDownloadFiles from 'w-dwload-dlp/src/autoDownloadFiles.mjs'

async function test() {

    //autoDownloadFiles, 無yt-dlp.exe或ffmpeg.exe時自動下載, 下載失敗則reject
    let { fpExeDlp, fpExeFfmpeg } = await autoDownloadFiles()

    console.log('fpExeDlp', fpExeDlp)
    // fpExeDlp D:\xxx\node_modules\w-dwload-dlp\yt-dlp\yt-dlp.exe

    console.log('fpExeFfmpeg', fpExeFfmpeg)
    // fpExeFfmpeg D:\xxx\node_modules\w-ffmpeg\src\ffmpeg.exe
}

    .catch((err) => {
