| + | ===== How to... ===== | ||
| + | |||
| + | ==== Add several modules to one js script? ==== | ||
| + | |||
| + | We will need two "main" modules. Then compile it like this: | ||
| + | <code> | ||
| + | elm make src/Main1.elm src/Main2.elm --output=main.js | ||
| + | </code> | ||
| + | |||
| + | After this you can call it like this: | ||
| + | <code> | ||
| + | <div id="elm-app1"></div> | ||
| + | <div id="elm-app2"></div> | ||
| + | |||
| + | <script src="main.js"></script> | ||
| + | <script> | ||
| + | var app = Elm.Main1.init({ | ||
| + | node: document.getElementById("elm-app1") | ||
| + | }); | ||
| + | var app2 = Elm.Main2.init({ | ||
| + | node: document.getElementById("elm-app2") | ||
| + | }); | ||
| + | </script> | ||
| + | </code> | ||
