  +Let's check if everything is OK before starting with Elm.
  +Start your `meteor` server: 
  +```shell
  +# under meteor-elm-app
   meteor
   ```

   == Elm
   
   === Install Parcel
   
  +We will use Parcel to build our Elm application and we will use the result of this build in our Meteor application
  +
  +To install Parcel, run this command
  +
   ```shell
   meteor npm i -D parcel
  -``
  +```
   
   === Install Elm
   
  +To install Elm, run this command
  +
   ```shell
   meteor npm i -D elm elm-format
  +```
  +
  +NOTE: elm-format is not mandatory but you should use it with your IDE to format on save and avoid problem at compile time
  +
  +We will also create a `script` in the `package.json` to call Elm easily like:
  +```shell
  +meteor npm run elm
  +```
  +
  +In your package.json, add this `elm` script:
  +```json
  +"scripts": {
  +    "elm": "elm",
  +    "start": "meteor run"
  +},
  +```
  +
  +You can validate your script by running:
  +```shell
  +meteor npm run elm -- --version
  +```
  +
  +You should see the version of Elm:
  +```
  +> elm "--version"
  +
  +0.19.1
   ```
   
   
  
positive.code: I discovered Meteor in 2015, I gave a talk about it (https://www.youtube.com/watch?v=AxIvfQXTqVo) and it still feels like "Wow!" when you start a project.
  So in this post I'll explain how I make the two work together, adding tailwind for the UI part (because I love tailwind too 😍) from scratch.

negative.code: ```
  
  NOTE: This configuration comes from the typescript template provided by Meteor.
  I just removed the support of JSX.
  
  === Create the file structure
  
  NOTE: We will setup a simple file structure here, for more complex projects, you should follow the guideline provided by Meteor https://guide.meteor.com/structure.html#javascript-structure
  
  Run these commands
  ```shell
  # under meteor-elm-app
  mkdir client server imports/api
  touch client/main.html client/main.ts client/main.css server/main.ts
  ```
  
  Your folder should be like this:
  
  ```shell
  # under meteor-elm-app
  ❯ tree -I node_modules                                              
  .
