Many of the scenarios where node is used for web development may encounter verification codes. Previously, I searched on github and found some class libraries such as node-captcha, they all need to rely on third-party graphics processing libraries or software. When I installed the cario graphics library, it was a great deal of effort, but we actually only used a little small feature of these graphics libraries, you can modify the cropping or production verification code for the slice size.
Let's
Use node to do a lot of web development can encounter the need to verify the code of the place, before the search on the GitHub, there are some such as Node-captcha class library, all need to rely on Third-party graphics processing library or software, as I installed Cario This graphics library, really cost a great deal of effort, But in fact we only use a little bit of these graphics library features, such as the size of the image to modify the crop, or production verification code.
