這門課主要是從小編在這六七年來對於後端開發的集大成,以 Node.js+VS Code 做為開發環境。
會開這門課程的原因,主要是因為後端運用廣泛,但是門檻高、人才難找。而前端工程師經過了 MVVM 框架及 JavaScript 的洗禮後,再加上 Node.js 的流行,轉職到後端會比其他語言多了一層優勢。所以這門課程希望能讓已經有 JavaScript 基礎的前端工程師,也能輕鬆進入後端開發的大門。
課程內容主要是從 Express.js 開始著手,以 TODO list 做為貫穿整門課程的專案,其中可以學到許多內容,像是:
🔥 如何活用 package.json 及 dotenv 讓你快速開發
🔥 express.js 最重要的 middleware 開發及如何擴充 req/res
🔥 如何使用 Heroku 讓你快速部署網站上雲
🔥 如何使用 New Relic 來觀測網站運作狀況
其中也會教大家如何撰寫 API 文件及 RESTful API 的串接實戰,像是:
🔥 request 失敗到底要用 200 還是 400 回應
🔥 使用 mock server 快速串接 API
🔥 使用 Markdown 快速撰寫 API 文件
而資料庫則會搭配 MongoDB 及 Redis 做為快速開發使用:
🔥 MongoDB 的 schema 設計、CRUD 及最重要的 aggregate 使用方式
🔥 Redis 的 set/get 及 expire 功能簡易使用

這門課也有兩個募資解鎖單元,分別是「如何使用 Redis 開發 autocomplete 功能」、「如何使用 BullMQ 縮短 API 的回應時間」,歡迎大家踴躍報名這門課程,對課程有任何疑問都可以在課程網頁留言喔!

小編在 Backend 台灣 (Backend Tw) 的留言沒想到這麼多人按讚,直接分享出來讓更多人知道好了。
分享一下新進 nodejs 想學後端的朋友,會用簡單的 expressjs 寫 RESTful API 之後,應該還有哪些要學的。
先簡單列一些,剩下歡迎各位大神補充喔!

~Updated Description on 2/15/2012~ : added some pros to both device.
To clarify, this comparison is the PCIe ver. not the USB ver. for the AVerMedia HD DVR. I do not own the USB ver. thus I can not give any input.
As for the New Hauppauge HD PVR Gaming edition, its basically the same as HD PVR 1212 with just the change of included software is different.
Recently purchased AVerMedia AVerTV HD DVR for streaming purposes.
Just want to compare the quality of the video recorded from both device at their max setting then rendered at 10mb bitrate.
This video may or may not help you choose between two capture device for future purchases. Just leave some comment below, for it might be some help to others that do consider purchasing either. Remember to read the following video description too.
Both are recorded thru component cables and at 720p res. AVerMedia AVerTV HD DVR has HDMI input but it has HDCP, which require me to use FRAPS if I do want to record thru HDMI. Either way, to give HD PVR a fair shake both is recorded thru component cables.
Note video source were split two/three ways; 1 to HDTV, 2 to HD PVR, 3 to HD DVR.
Here's my own opinion, HD PVR has a nicer default color setting and brightness but of course using SONY Vegas or any advance video editing software can add tweak to those settings.
=====================================
Now to List the Pros & Cons for each device:
Hauppauge HD PVR 1212:
Pros:
-Hardware Encoder (Does not require a mid/or high end PC to record HD videos) (Side note: I used my Acer AspireOne Intel Atom Processor mini laptop to record before and the video came out fine. Just that if you watch it in an Atom Processor, you might see lag/frame skip but just transfer that video file to a better PC. Then, you'll see its not the video but the processor (Intel Atom) can't process the video to be frame skip/lag free)
-Has optical audio input for 5.1ch surround sound recording
-New Drivers + New Xsplit can now use HD PVR as a camera source to broadcast without the need screen capturing.
-Only if you are using screen capturing to broadcast then you can use the Arcsoft TotalMedia to record while simultaneously broadcast.
Cons:
-Video lag/delay (Cannot directly play from PC due to 1-5sec video delay)
-For FME broadcasting software only! it cannot directly use HD PVR as an video input source. If you use xsplit it render this con pointless.
(Req. Screen Capturing Program to Screen Cap the Total Media Extreme Video Window, thus require more processing speed. in another words needs a mid to high end PC if you want to use HD PVR to broadcast live.)
-~$190 price tag??, not alot might willing to spend this much I guess.
AVerMedia AVerTV HD DVR:
Pros:
-No Video lag/delay (Can play directly using the PC and don't need to split video source to HDTV to play)
-FME, Xsplit & other broadcasting software can directly use HD DVR as input source (Ideal way for using to broadcast live)
-You can use screen capturing to broadcast so that you can record with Aver Media Center while simultaneously broadcast.
- ~$85 price tag, cheap compare to many others HD capture device out there.
Cons:
-Not Hardware Encoder (Req. a mid/or high end PC to record HD quality videos)
-HDMI input is HDCP'ed (Can only view HDCP content thru its own provided software and no recording functionally when watching through HDMI, but can bypass if FRAPS is used)
-Req. PCI-E slot (Note you can plug this into a x16 slot too, if you don't have any available x1 slot. Which is what I'm currently doing so.)
