Router and Parameters
Create a file named get.yap with the following content:
html `<html><body>Hello, YAP!</body></html>`Execute the following commands:
gop mod init hello
gop get github.com/goplus/yap@latest
gop mod tidy
gop run .A simplest web program is running now. At this time, if you visit http://localhost:8080, you will get:
Hello, YAP!
YAP uses filenames to define routes. get.yap's route is get "/" (GET homepage), and get_p_#id.yap's route is get "/p/:id" (In fact, the filename can also be get_p_:id.yap, but it is not recommended because : is not allowed to exist in filenames under Windows).
Let's create a file named get_p_#id.yap with the following content:
json {
"id": ${id},
}Execute gop run . and visit http://localhost:8080/p/123, you will get:
{"id": "123"}
YAP Template
In most cases, we don't use the html directive to generate html pages, but use the yap template engine. See get_p_#id.yap:
yap "article", {
"id": ${id},
}It means finding a template called article to render. See yap/article_yap.html:
<html>
<head><meta charset="utf-8"/></head>
<body>Article {{.id}}</body>
</html>Run at specified address
By default the YAP server runs on localhost:8080, but you can change it in main.yap file:
run ":8888"
