수업소개
상세보기 페이지를 Express 버전으로 변환해볼 것입니다. 이 과정에서 query string을 사용하지 않는 pretty url(clean url, semantic url..)로 라우트 기능을 구현하는 방법을 살펴보겠습니다.
강의 1
Clean URL로 Route를 구현하는 방법을 소개해드립니다.
소스코드
main.js
var express = require('express') var app = express() var fs = require('fs'); var template = require('./lib/template.js'); //route, routing //app.get('/', (req, res) => res.send('Hello World!')) app.get('/', function(request, response) { fs.readdir('./data', function(error, filelist){ var title = 'Welcome'; var description = 'Hello, Node.js'; var list = template.list(filelist); var html = template.HTML(title, list, `<h2>${title}</h2>${description}`, `<a href="/create">create</a>` ); response.send(html); }); }); app.get('/page/:pageId', function(request, response) { response.send(request.params); }); app.listen(3000, function() { console.log('Example app listening on port 3000!') });
강의2
상세보기 페이지를 완성해봅시다.
소스코드
main.js
var express = require('express') var app = express() var fs = require('fs'); var path = require('path'); var sanitizeHtml = require('sanitize-html'); var template = require('./lib/template.js'); //route, routing //app.get('/', (req, res) => res.send('Hello World!')) app.get('/', function(request, response) { fs.readdir('./data', function(error, filelist){ var title = 'Welcome'; var description = 'Hello, Node.js'; var list = template.list(filelist); var html = template.HTML(title, list, `<h2>${title}</h2>${description}`, `<a href="/create">create</a>` ); response.send(html); }); }); app.get('/page/:pageId', function(request, response) { fs.readdir('./data', function(error, filelist){ var filteredId = path.parse(request.params.pageId).base; fs.readFile(`data/${filteredId}`, 'utf8', function(err, description){ var title = request.params.pageId; var sanitizedTitle = sanitizeHtml(title); var sanitizedDescription = sanitizeHtml(description, { allowedTags:['h1'] }); var list = template.list(filelist); var html = template.HTML(sanitizedTitle, list, `<h2>${sanitizedTitle}</h2>${sanitizedDescription}`, ` <a href="/create">create</a> <a href="/update?id=${sanitizedTitle}">update</a> <form action="delete_process" method="post"> <input type="hidden" name="id" value="${sanitizedTitle}"> <input type="submit" value="delete"> </form>` ); response.send(html); }); }); }); app.listen(3000, function() { console.log('Example app listening on port 3000!') });
lib/template.js
module.exports = { HTML:function(title, list, body, control){ return ` <!doctype html> <html> <head> <title>WEB1 - ${title}</title> <meta charset="utf-8"> </head> <body> <h1><a href="/">WEB</a></h1> ${list} ${control} ${body} </body> </html> `; },list:function(filelist){ var list = '<ul>'; var i = 0; while(i < filelist.length){ list = list + `<li><a href="/page/${filelist[i]}">${filelist[i]}</a></li>`; i = i + 1; } list = list+'</ul>'; return list; } }
