javascript - node.js: delete require.cache not working -
i'm trying build hmr koa2 development chokidar.
changing text in ./middlewares/render triggers chokidar file-watch event, , require.cache cleared expected, when reload page, text rendered not changed.
./index.js
const path = require('path'); const http = require('http'); const koa = require('koa'); const chokidar = require('chokidar'); const views = require('./middlewares/views.js'); const render = require('./middlewares/render.js'); const port = 3000; const app = new koa(); app.use(views); app.use(render); const server = http.createserver(app.callback()); server.listen(port, function() { console.log('server listening on port: %s', port); }); const watcher = chokidar.watch([ path.resolve(__dirname, './middlewares'), ]); watcher.on('ready', function() { watcher.on('all', function(event, filename) { console.log('clearing module cache...'); object.keys(require.cache).foreach(function (id) { if (/[\/\\]middlewares[\/\\]/.test(id)) { console.log('delete cache: %s', id); delete require.cache[id]; } }); }); }); ./middlewares/views.js
const views = require('koa-views'); module.exports = views('./templates', { http: 'ejs', extension: 'ejs', }); ./middlewares/render.js
module.exports = async (ctx, next) => { // changing text, triggers chokidar file-watch event. // require.cache seems cleared immediately. // when reload page, text not changes! const content = 'test delete require.cache.'; await ctx.render('main.ejs', { content: content }); }; ./templates/index.ejs

okay... repository helped.
previously
const views = require('./middlewares/views.js'); const render = require('./middlewares/render.js'); app.use(views); app.use(render); now
app.use(async (ctx, next) => { const views = require('./middlewares/views.js'); await views(ctx, next); }); app.use(async (ctx, next) => { const render = require('./middlewares/render.js'); await render(ctx, next); });
