FE Dev Server
FE Dev Server target to help frontend web developers create view template, styles and js easily. It try the best to simulate real server environment which can help you to make you job done.
Features
- Various template engines and embedded page data.
- Url simulation
- Mock data in file
- Proxy configuration
Quick start
Install it as a command line tool with the following step:
Install module globally
$ npm install -g fe-dev-server
create project folder and get into the folder
$ mkdir workdir && cd workdir
initial the project folder
$ fds init
start up server
$ fds server
start up server & open browser
$ fds server -o
Also, it can be integrated into your own project as a node module.
var fds = require('fe-dev-server');
var app = fds({
basePath: __dirname,
mockFolder: 'data',
port: 8001
});
Routes
Routes is stored in routes.js
as key/value pairs by default.
Sample:
module.exports = {
// set /test route to test.html page, default http method is GET
'/test': 'test.html',
// set /books route to books.pug template with GET method
'GET::/books': 'books.pug',
// set json api with a json file in mock folder
'POST::/api/books': 'mock::books.json',
// mock file can also be a js file, which has more power to do the customization
'GET::/api/category': 'mock::category.js',
// fds works with java template such as jsp;
// before do this, you have to set enableJava to true in your fds-config.js file
'/jsp-page': 'books.jsp',
// it allow your route to proxy an online page
'/proxy-api': 'http://www.github.com/zhex.json',
// proxy can do fuzzy mapping;
// in the setting, if you visit /books/hello, it will map to http://example.com/books/hello
'ALL::/books/:pattern*': 'http://example.com/books/'
};
the rule is '[method]::[route_url]': '[template_file]'
.
Allowed method: GET
, POST
, PUT
, PATCH
, DETELE
GET
will be used if it is not specified.
If you want to setup an ajax api url, you can set the template to a json file. The server will look for the json/js file in view folder and send back it as a json object. the data in the view folder sounds not make sense. So if you want put the json/js file in the mock folder, then you can add a mock::
prefix in the template path, then the server will look for the file in mock folder.
If the mock file is a js file, then it is good to define as a module function:
module.exports = function (data, utils) {
return {
id: data.params.id,
name: data.query.name || 'hello world',
content: data.body.content
};
};
The data.params
is the match variable collection in the particular route; The data.query
is the query data from request url, so you can easily test your page with different api return.
utils
provide some easy to use method to handle the data.
available method:
- utils.isObject(obj)
- utils.isArray(obj)
- utils.isFunc(obj)
- utils.contains(array, item)
- utils.serialize(obj)
- utils.assign() - which is object-assign library
- utils.moment() - which is moment library
- utils.Mock - which is mockjs library
Also, you can add $$header
in the data file to extend http response header, and using $$delay
to set simulate the http connection delay.
{
"$$header": {
"x-access-token": "abcs"
},
"$$delay": 3000,
"title": "hello world"
}
embedded template engines
- pug
- handlebars
- ejs
- jsp (java)
- velocity (java)
Configuration
You can custom your configuration in fds-config.js
file.
defaultConfig = {
basePath: path.resolve(__dirname, './example'),
publicFolder: 'public',
viewFolder: 'views',
mockFolder: 'mocks',
routeFile: 'routes.js',
port: 3000
}
basePath
The base path of the project, all other folder settings are related to base path.
viewFolder
default: 'views'
Where you can put your view template files.
mockFolder
default: 'mocks'
Save you mock data into this folder. each view template will have a matched json data file will be loaded automatcially.
For example: we have a ${viewFolder}/projects/index.html
template, then data in ${viewFolder}/projects/index.json
file will be auto loaded into the template.
publicFolder
default: 'public'
Where you can put your image, style and js files here. This folder is set by express.static()
routeFile
default: 'routes.js'
Routes mapping file
mockExts
default: ['.js', '.json']
Some people like to set mockFolder as the same as viewFolder for convinence reason, mockExts
give you the ability to define your own mock file type to avoid the conflict issue. Also, the ext order in array demonstrate the priority from higher to lower.
port
default: 3000
Express server port
enableJava
default: true
Sometimes you don't need to support java templates, you can turn it off with this property to false
.
livereload
default: true
livereload is awesome, it will refresh your browser automatically after anything changed. If you dont like this feature, you can set it to false
to switch it off. also you can set it as a livereload option object;
open
default: { route: '/', browser: ['google chrome'] }
Browser setting allow you to open dev site automatically on server started with -o
option in cli. It will open google chrome by default.
$ fds server -o
