Package Exports
- realm-js
This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (realm-js) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.
Readme
realm-js
RealmJs is a brand new universal transpiler with built-in dependency injection.
Features
- 100% Universal
- Improved import system - Packages, aliases
- Promise based
- EC7 friendly - decorators
- Automatic environment separation (backend, frontend, universal)
- Backend encapsulation / Bridges
- Extremely fast compilation (50-70ms) to transpile a big project
Usage
"use realm";
import myModule from myapp;
import lodash as _ from myapp.utils;
class MySuperClass {
}
export MySuperClass;
Realm transpiler goes through files and converts, say MySuperClass.js file into
realm.module("test.MySuperClass", ["myapp.myModule", "myapp.utils.lodash"], function (myModule, _) {
class MySuperClass {
}
return MySuperClass;
});
Header types
Univeral mode. File will be put into universal.js
"use realm";
Frontend mode. File will be put into frontend.js
"use realm frontend";
Frontend mode without wrapping. File will be put into frontend.js
"use realm frontend-raw";
Backend mode. File will be put into backend.js
"use realm backend";
Backend mode without wrapping. File will be put into backend.js
"use realm backend-raw";
Bridge mode, the source will be put into backend.js, interface into frontend.js
"use realm bridge";
Using Bridges
Sometimes you need to have your code encapsulated. Say, secured calls involving authentication; In this case, bridge most is the most suitable case.
Before proceeding, you need to install realm-router (it will actually proxy frontend requests) Set up you express application like so:
var router = require("realm-router");
realm.require('realm.router.Express', function(router) {
app.use(router(["realm.router.bridge"]))
})
Include realm-router frontend build to your html file. And start bridging!
"use realm bridge";
class Auth {
static login()
{
}
}
export Auth
Remember that only static methods are exposed.
Transpiler
Universal transpiler will output 3 files: backend, frontend, universal
gulp.task('build-universal', function() {
return realm.transpiler2.universal(__dirname + "/test-universal/", "test_build/").then(function(changes) {
console.log(changes)
})
});
Install
npm install realm-js --save
Under the hood
You can use realm-js without transpiler
Creating modules/services
realm.module("MyFirstModule", function() {
return new Promise(function(resolve, reject){
return resolve({hello : "world"})
});
});
realm.module("MySecondModule", function(MyFirstModule) {
console.log(MyFirstModule);
});
Require a module
Code:
realm.require(function(MySecondModule){
console.log(MySecondModule)
});
Will resolve all required dependencies. The ouput:
{hello: "world"}
Require a package
You can require a package if you like.
realm.requirePackage("app.components").then(function(components){
});
Annotation
Clearly, if you don't use ec6, or any other transpilers, you need to annotate modules
realm.module("myModule", ["moduleA", "moduleB"], function(moduleA, moduleB){
})
A simple import
If a module does not belong to any package:
import Module
If a module belongs to a package:
import Module from app
Giving it alias
import Module as mod from app
Explicit module name (not recommended)
Contribute
Please, contribute. The code isn't in its best shape but rocks!
