Define the path where the ejs-files are located. Define some url's which should be escaped like the pure api-query. To define a url-prefix use the option prefix.
const Pusudb = require('pusudb')
const pusudb = new Pusudb(3000, 'localhost', { log : true, prefix : '/api'})
const Render = require('pusudb-use-ejs')
const render = new Render(__dirname + '/ejs', ['/public', '/api'/*, blocked pathnames */], { prefix : '/ejs' /*, ejs-options, see ejs-docs */ })
//add the middleware to the pusudb
pusudb.use('http', render.serve)
pusudb.listen(function(port, host){
console.log('pusudb listening:', port, host)
})Single query and use data in ejs
- http://localhost:3000/ejs/index/api/db/stream
- <%= data => and <%= err => in ejs-file
Multiple queries and use data in ejs
- http://localhost:3000/ejs/index/api/select/list?nav=db,stream&user=db,get,key+person:AEYC8Y785
- <%= nav => and <%= user => in ejs-file
Add render-data in instance
Reserved props are err, db, meta and data. Use the props in ejs-file like <%= title %>.
// Set global data for any
render.setRenderGlobalData({ title : 'Page-Title', description : '42.'})
console.log( render.getRenderGlobalData() )
// Set data per file
render.setRenderFileData('index.ejs', { content : 'Some content', page : 'Index'})
render.setRenderFileData('contact.ejs', { address : '...', phone : '....'})
console.log( render.getRenderFileData() )Add render-data in a pusudb-middleware
Add some props to req.docs and use the data in the ejs-file.
pusudb.useBefore('http', function(req, res, next){
if(!req.url.startsWith('/api')){
req.render['ticker'] = 'You can now use <%= ticker %> in the ejs-file'
req.render['lang'] = 'de' // in ejs <%= lang %>
req.render['title'] = 'PUSUDB-STUDIO' // in ejs <%= title %>
req.render['scripts'] = [] // add some script paths and loop the array in ejs
req.render['styles'] = []
req.render['favicon'] = '/public/images/favicon.ico' // in ejs <%= favicon %>
next()
}

next()
}
