| # --description--
 | |
| 
 | |
| Build a full stack JavaScript app that is functionally similar to this: <https://exercise-tracker.freecodecamp.rocks/>. Working on this project will involve you writing your code using one of the following methods:
 | |
| 
 | |
| -   Clone [this GitHub repo](https://github.com/freeCodeCamp/boilerplate-project-exercisetracker/) and complete your project locally.
 | |
| -   Use [our Replit starter project](https://replit.com/github/freeCodeCamp/boilerplate-project-exercisetracker) to complete your project.
 | |
| -   Use a site builder of your choice to complete the project. Be sure to incorporate all the files from our GitHub repo.
 | |
| 
 | |
| When you are done, make sure a working demo of your project is hosted somewhere public. Then submit the URL to it in the `Solution Link` field. Optionally, also submit a link to your project's source code in the `GitHub Link` field.
 | |
| 
 | |
| # --hints--
 | |
| 
 | |
| You should provide your own project, not the example URL.
 | |
| 
 | |
| ```js
 | |
| (getUserInput) => {
 | |
|   const url = getUserInput('url');
 | |
|   assert(
 | |
|     !/.*\/exercise-tracker\.freecodecamp\.rocks/.test(getUserInput('url'))
 | |
|   );
 | |
| };
 | |
| ```
 | |
| 
 | |
| You can `POST` to `/api/users` with form data `username` to create a new user. The returned response will be an object with `username` and `_id` properties.
 | |
| 
 | |
| ```js
 | |
| async (getUserInput) => {
 | |
|   const url = getUserInput('url');
 | |
|   const res = await fetch(url + '/api/users', {
 | |
|     method: 'POST',
 | |
|     headers: { 'Content-Type': 'application/x-www-form-urlencoded' },
 | |
|     body: `username=fcc_test_${Date.now()}`.substr(0, 29)
 | |
|   });
 | |
|   if (res.ok) {
 | |
|     const { _id, username } = await res.json();
 | |
|     assert.exists(_id);
 | |
|     assert.exists(username);
 | |
|   } else {
 | |
|     throw new Error(`${res.status} ${res.statusText}`);
 | |
|   }
 | |
| };
 | |
| ```
 | |
| 
 | |
| You can make a `GET` request to `/api/users` to get an array of all users. Each element in the array is an object containing a user's `username` and `_id`.
 | |
| 
 | |
| ```js
 | |
| async (getUserInput) => {
 | |
|   const url = getUserInput('url');
 | |
|   const res = await fetch(url + '/api/users');
 | |
|   if (res.ok) {
 | |
|     const data = await res.json();
 | |
|     assert.isArray(data);
 | |
|     assert.isString(data[0].username);
 | |
|     assert.isString(data[0]._id);
 | |
|   } else {
 | |
|     throw new Error(`${res.status} ${res.statusText}`);
 | |
|   }
 | |
| };
 | |
| ```
 | |
| 
 | |
| You can `POST` to `/api/users/:_id/exercises` with form data `description`, `duration`, and optionally `date`. If no date is supplied, the current date will be used. The response returned will be the user object with the exercise fields added.
 | |
| 
 | |
| ```js
 | |
| async (getUserInput) => {
 | |
|   const url = getUserInput('url');
 | |
|   const res = await fetch(url + '/api/users', {
 | |
|     method: 'POST',
 | |
|     headers: { 'Content-Type': 'application/x-www-form-urlencoded' },
 | |
|     body: `username=fcc_test_${Date.now()}`.substr(0, 29)
 | |
|   });
 | |
|   if (res.ok) {
 | |
|     const { _id, username } = await res.json();
 | |
|     const expected = {
 | |
|       username,
 | |
|       description: 'test',
 | |
|       duration: 60,
 | |
|       _id,
 | |
|       date: 'Mon Jan 01 1990'
 | |
|     };
 | |
|     const addRes = await fetch(url + `/api/users/${_id}/exercises`, {
 | |
|       method: 'POST',
 | |
|       headers: { 'Content-Type': 'application/x-www-form-urlencoded' },
 | |
|       body: `description=${expected.description}&duration=${expected.duration}&date=1990-01-01`
 | |
|     });
 | |
|     if (addRes.ok) {
 | |
|       const actual = await addRes.json();
 | |
|       assert.deepEqual(actual, expected);
 | |
|     } else {
 | |
|       throw new Error(`${addRes.status} ${addRes.statusText}`);
 | |
|     }
 | |
|   } else {
 | |
|     throw new Error(`${res.status} ${res.statusText}`);
 | |
|   }
 | |
| };
 | |
| ```
 | |
| 
 | |
| You can make a `GET` request to `/api/users/:_id/logs` to retrieve a full exercise log of any user. The returned response will be the user object with a `log` array of all the exercises added. Each log item has the `description`, `duration`, and `date` properties.
 | |
| 
 | |
| ```js
 | |
| async (getUserInput) => {
 | |
|   const url = getUserInput('url');
 | |
|   const res = await fetch(url + '/api/users', {
 | |
|     method: 'POST',
 | |
|     headers: { 'Content-Type': 'application/x-www-form-urlencoded' },
 | |
|     body: `username=fcc_test_${Date.now()}`.substr(0, 29)
 | |
|   });
 | |
|   if (res.ok) {
 | |
|     const { _id, username } = await res.json();
 | |
|     const expected = {
 | |
|       username,
 | |
|       description: 'test',
 | |
|       duration: 60,
 | |
|       _id,
 | |
|       date: new Date().toDateString()
 | |
|     };
 | |
|     const addRes = await fetch(url + `/api/users/${_id}/exercises`, {
 | |
|       method: 'POST',
 | |
|       headers: { 'Content-Type': 'application/x-www-form-urlencoded' },
 | |
|       body: `description=${expected.description}&duration=${expected.duration}`
 | |
|     });
 | |
|     if (addRes.ok) {
 | |
|       const logRes = await fetch(url + `/api/users/${_id}/logs`);
 | |
|       if (logRes.ok) {
 | |
|         const { log } = await logRes.json();
 | |
|         assert.isArray(log);
 | |
|         assert.equal(1, log.length);
 | |
|       } else {
 | |
|         throw new Error(`${logRes.status} ${logRes.statusText}`);
 | |
|       }
 | |
|     } else {
 | |
|       throw new Error(`${addRes.status} ${addRes.statusText}`);
 | |
|     }
 | |
|   } else {
 | |
|     throw new Error(`${res.status} ${res.statusText}`);
 | |
|   }
 | |
| };
 | |
| ```
 | |
| 
 | |
| A request to a user's log (`/api/users/:_id/logs`) returns an object with a `count` property representing the number of exercises returned.
 | |
| 
 | |
| ```js
 | |
| async (getUserInput) => {
 | |
|   const url = getUserInput('url');
 | |
|   const res = await fetch(url + '/api/users', {
 | |
|     method: 'POST',
 | |
|     headers: { 'Content-Type': 'application/x-www-form-urlencoded' },
 | |
|     body: `username=fcc_test_${Date.now()}`.substr(0, 29)
 | |
|   });
 | |
|   if (res.ok) {
 | |
|     const { _id, username } = await res.json();
 | |
|     const expected = {
 | |
|       username,
 | |
|       description: 'test',
 | |
|       duration: 60,
 | |
|       _id,
 | |
|       date: new Date().toDateString()
 | |
|     };
 | |
|     const addRes = await fetch(url + `/api/users/${_id}/exercises`, {
 | |
|       method: 'POST',
 | |
|       headers: { 'Content-Type': 'application/x-www-form-urlencoded' },
 | |
|       body: `description=${expected.description}&duration=${expected.duration}`
 | |
|     });
 | |
|     if (addRes.ok) {
 | |
|       const logRes = await fetch(url + `/api/users/${_id}/logs`);
 | |
|       if (logRes.ok) {
 | |
|         const { count } = await logRes.json();
 | |
|         assert(count);
 | |
|       } else {
 | |
|         throw new Error(`${logRes.status} ${logRes.statusText}`);
 | |
|       }
 | |
|     } else {
 | |
|       throw new Error(`${addRes.status} ${addRes.statusText}`);
 | |
|     }
 | |
|   } else {
 | |
|     throw new Error(`${res.status} ${res.statusText}`);
 | |
|   }
 | |
| };
 | |
| ```
 | |
| 
 | |
| You can add `from`, `to` and `limit` parameters to a `/api/users/:_id/logs` request to retrieve part of the log of any user. `from` and `to` are dates in `yyyy-mm-dd` format. `limit` is an integer of how many logs to send back.
 | |
| 
 | |
| ```js
 | |
| async (getUserInput) => {
 | |
|   const url = getUserInput('url');
 | |
|   const res = await fetch(url + '/api/users', {
 | |
|     method: 'POST',
 | |
|     headers: { 'Content-Type': 'application/x-www-form-urlencoded' },
 | |
|     body: `username=fcc_test_${Date.now()}`.substr(0, 29)
 | |
|   });
 | |
|   if (res.ok) {
 | |
|     const { _id, username } = await res.json();
 | |
|     const expected = {
 | |
|       username,
 | |
|       description: 'test',
 | |
|       duration: 60,
 | |
|       _id,
 | |
|       date: new Date().toDateString()
 | |
|     };
 | |
|     const addExerciseRes = await fetch(url + `/api/users/${_id}/exercises`, {
 | |
|       method: 'POST',
 | |
|       headers: { 'Content-Type': 'application/x-www-form-urlencoded' },
 | |
|       body: `description=${expected.description}&duration=${expected.duration}&date=1990-01-01`
 | |
|     });
 | |
|     const addExerciseTwoRes = await fetch(url + `/api/users/${_id}/exercises`, {
 | |
|       method: 'POST',
 | |
|       headers: { 'Content-Type': 'application/x-www-form-urlencoded' },
 | |
|       body: `description=${expected.description}&duration=${expected.duration}&date=1990-01-02`
 | |
|     });
 | |
|     if (addExerciseRes.ok && addExerciseTwoRes.ok) {
 | |
|       const logRes = await fetch(
 | |
|         url + `/api/users/${_id}/logs?from=1989-12-31&to=1990-01-03`
 | |
|       );
 | |
|       if (logRes.ok) {
 | |

 | |

 | |
|         assert.equal(2, log.length);
 | |
|       } else {
 | |
|         throw new Error(`${logRes.status} ${logRes.statusText}`);
 | |
|       }
 | |
|       const limitRes = await fetch(
 | |
|         url + `/api/users/${_id}/logs?limit=1`
 | |
|       );
 | |
|       if (limitRes.ok) {
 | |
|         const { log } = await limitRes.json();
 | |
|         assert.isArray(log);
 | |

 | |
