Metric-Imperial Converter

Build a full-stack JavaScript app that is functionally similar to this: <a href="https://metric-imperial-converter.freecodecamp.rocks/" target="_blank" rel="noopener noreferrer nofollow">https://metric-imperial-converter.freecodecamp.rocks/</a>. Working on this project will involve you writing your code using one of the following methods: - Clone <a href="https://github.com/freeCodeCamp/boilerplate-project-metricimpconverter/" target="_blank" rel="noopener noreferrer nofollow">this GitHub repo</a> and complete your project locally. - Use a site builder of your choice to complete the project. Be sure to incorporate all the files from our GitHub repo. **Note:** This project's tests do not work when using `glitch.com`. # --instructions-- - Complete the necessary conversion logic in `/controllers/convertHandler.js` - Complete the necessary routes in `/routes/api.js` - Copy the `sample.env` file to `.env` and set the variables appropriately - To run the tests automatically, add `NODE_ENV=test` in your `.env` file - To run the tests in the console, use the command `npm run test`. Write the following tests in `tests/1_unit-tests.js`: - `convertHandler` should correctly read a whole number input. - `convertHandler` should correctly read a decimal number input. - `convertHandler` should correctly read a fractional input. - `convertHandler` should correctly read a fractional input with a decimal. - `convertHandler` should correctly return an error on a double-fraction (i.e. `3/2/3`). - `convertHandler` should correctly default to a numerical input of `1` when no numerical input is provided. - `convertHandler` should correctly read each valid input unit. - `convertHandler` should correctly return an error for an invalid input unit. - `convertHandler` should return the correct return unit for each valid input unit. - `convertHandler` should correctly return the spelled-out string unit for each valid input unit. - `convertHandler` should correctly convert `gal` to `L`. - `convertHandler` should correctly convert `L` to `gal`. - `convertHandler` should correctly convert `mi` to `km`. - `convertHandler` should correctly convert `km` to `mi`. - `convertHandler` should correctly convert `lbs` to `kg`. - `convertHandler` should correctly convert `kg` to `lbs`. Write the following tests in `tests/2_functional-tests.js`: - Convert a valid input such as `10L`: `GET` request to `/api/convert`. - Convert an invalid input such as `32g`: `GET` request to `/api/convert`. - Convert an invalid number such as `3/7.2/4kg`: `GET` request to `/api/convert`. - Convert an invalid number AND unit such as `3/7.2/4kilomegagram`: `GET` request to `/api/convert`. - Convert with no number such as `kg`: `GET` request to `/api/convert`.
