TypeScript outputs JavaScript, but what are you supposed to do with it? This lesson shows how to take the output and use SystemJS as the module loader so that you can use the files in your browser.
Could not find systemjs at https://npmcdn.com.
However, I found a copy to use at https://cdnjs.com/libraries/systemjs
I'm getting an error on the lines of "system.js:4 Uncaught (in promise) Error: (SystemJS) Unexpected token <". Here is my System.config object: System.config = { packages: { "dist": { "defaultExtension": "js", "main": "main" } } }; System.import("dist");
Any suggestions?
System.config({
packages: {
"dist": {
"defaultExtension": 'js',
"main": 'app'
}
}
});
System.import("dist")
Dont use equals "=", just send as parameter to config method
Hi John, thanks for this great video, which includes a bunch of useful tips in addition to the main topic.
I want my Typescript code to compile into a single JS file. I've accomplished this using the simple tsconfig parameter outFile. However I now have a single file with many SystemJS modules. How do I load all of those modules into my index.html? I can't get it to work
Include the output bundle in a script tag <script src="output.js">
then System.import('whatever-the-entry-file-is')
I'm getting this error on my console when I open the url:
common.js:83 Uncaught (in promise) Error: two_1.Two is not a constructor Evaluating http://localhost:3005/dist/main.js Loading dist at Object.eval (main.js:3) at eval (main.js:12) at eval (main.js:13) at eval (<anonymous>) at Pe (evaluate.js:106) at instantiate.js:365 at j (register-loader.js:658) at S (register-loader.js:609) at x (register-loader.js:518) at register-loader.js:119
Someone help me please, thank you
Big thanks, John. I'm starting to love TypeScript.
~~So if you are running http-server -c-1
in ts-lessons
folder ... how are you able to access index.html
? Because it's in src
folder and when I go to http://localhost:8080
it just shows me the list of directories/files.~~
Got it, index.html
goes into the ts-lessons
directory and not the src
one. :)
P.S. Also, the strikethrough markdown doesn't seem to be working here! :/
so basically System.js functions the same as Browserify?
This lesson is quite outdated.
