# --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.
|
|
|
|
# --instructions--
|
|
|
|
Your responses should have the following structures.
|
|
|
|
Exercise:
|
|
|
|
```js
|
|
{
|
|
username: "fcc_test",
|
|
description: "test",
|
|
duration: 60,
|
|
date: "Mon Jan 01 1990",
|
|
_id: "5fb5853f734231456ccb3b05"
|
|
}
|
|
```
|
|
|
|
User:
|
|
|
|
```js
|
|
{
|
|
username: "fcc_test",
|
|
_id: "5fb5853f734231456ccb3b05"
|
|
}
|
|
```
|
|
|
|
Log:
|
|
|
|
```js
|
|
{
|
|
username: "fcc_test",
|
|
count: 1,
|
|
_id: "5fb5853f734231456ccb3b05",
|
|
log: [{
|
|
description: "test",
|
|
duration: 60,
|
|
date: "Mon Jan 01 1990",
|
|
}]
|
|
}
|
|
```
|
|
|
|
**Hint:** For the `date` property, the `toDateString` method of the `Date` API can be used to achieve the expected output.
|
|
|
|
# --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.
|
|
|
|
```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_${Date.now()}`.substr(0, 29)
|
|
});
|
|
assert.isTrue(res.ok);
|
|
if(!res.ok) {
|
|
throw new Error(`${res.status} ${res.statusText}`)
|
|
};
|
|
};
|
|
```
|
|
|
|
The returned response from `POST /api/users` with form data `username` will be an object with `username` and `_id` properties.
|
|
|
|
```js
|
|
async (getUserInput) => {
|
|
const url = getUserInput('url');
|
|
const res = await fetch(url + '/api/users', {
|
|
method: 'POST',
|
|
headers: { 'Content-Type': 'application/x-www-form-urlencoded' },
|
|
body: `username=fcc_test_${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} ${res.statusText}`);
|
|
}
|
|
};
|
|
```
|
|
|
|
You can make a `GET` request to `/api/users` to get a list of all users.
|
|
|
|
```js
|
|
async(getUserInput) => {
|
|
const url = getUserInput('url');
|
|
const res = await fetch(url + '/api/users');
|
|
assert.isTrue(res.ok);
|
|
if(!res.ok) {
|
|
throw new Error(`${res.status} ${res.statusText}`)
|
|
};
|
|
};
|
|
```
|
|
|
|
The `GET` request to `/api/users` returns an array.
|
|
|
|
```js
|
|
async(getUserInput) => {
|
|
const url = getUserInput('url');
|
|
const res = await fetch(url + '/api/users');
|
|
if(res.ok){
|
|
const users = await res.json();
|
|
assert.isArray(users);
|
|
} else {
|
|
throw new Error(`${res.status} ${res.statusText}`);
|
|
};
|
|
};
|
|
```
|
|
|
|
Each element in the array returned from `GET /api/users` is an object literal containing a user's `username` and `_id`.
|
|
|
|
```js
|
|
async(getUserInput) => {
|
|
const url = getUserInput('url');
|
|
const res = await fetch(url + '/api/users');
|
|
if(res.ok){
|
|
const users = await res.json();
|
|
const user = users[0];
|
|
assert.exists(user);
|
|
assert.exists(user.username);
|
|
assert.exists(user._id);
|
|
assert.isString(user.username);
|
|
assert.isString(user._id);
|
|
} else {
|
|
throw new Error(`${res.status} ${res.statusText}`);
|
|
};
|
|
};
|
|
```
|
|
|
|
You can `POST` to `/api/users/:_id/exercises` with form data `description`, `duration`, and optionally `date`. If no date is supplied, the current date will be used.
|
|
|
|
```js
|
|
async (getUserInput) => {
|
|
const url = getUserInput('url');
|
|
const res = await fetch(url + '/api/users', {
|
|
method: 'POST',
|
|
headers: { 'Content-Type': 'application/x-www-form-urlencoded' },
|
|
body: `username=fcc_test_${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=${expected.duration}&date=1990-01-01`
|
|
});
|
|
assert.isTrue(addRes.ok);
|
|
if(!addRes.ok) {
|
|
throw new Error(`${addRes.status} ${addRes.statusText}`)
|
|
};
|
|
} else {
|
|
throw new Error(`${res.status} ${res.statusText}`);
|
|
}
|
|
};
|
|
```
|
|
|
|
The response returned from `POST /api/users/:_id/exercises` will be the user object with the exercise fields added.
|
|
|
|
```js
|
|
async (getUserInput) => {
|
|
const url = getUserInput('url');
|
|
const res = await fetch(url + '/api/users', {
|
|
method: 'POST',
|
|
headers: { 'Content-Type': 'application/x-www-form-urlencoded' },
|
|
body: `username=fcc_test_${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=${expected.duration}&date=1990-01-01`
|
|
});
|
|
if (addRes.ok) {
|
|
const actual = await addRes.json();
|
|
assert.deepEqual(actual, expected);
|
|
assert.isString(actual.description);
|
|
assert.isNumber(actual.duration);
|
|
assert.isString(actual.date);
|
|
} else {
|
|
throw new Error(`${addRes.status} ${addRes.statusText}`);
|
|
}
|
|
} else {
|
|
throw new Error(`${res.status} ${res.statusText}`);
|
|
}
|
|
};
|
|
```
|
|
|
|
You can make a `GET` request to `/api/users/:_id/logs` to retrieve a full exercise log of any user.
|
|
|
|
```js
|
|
async (getUserInput) => {
|
|
const url = getUserInput('url');
|
|
const res = await fetch(url + '/api/users', {
|
|
method: 'POST',
|
|
headers: { 'Content-Type': 'application/x-www-form-urlencoded' },
|
|
body: `username=fcc_test_${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`);
|
|
assert.isTrue(logRes.ok);
|
|
if(!logRes.ok) {
|
|
throw new Error(`${logRes.status} ${logRes.statusText}`)
|
|
};
|
|
} else {
|
|
throw new Error(`${addRes.status} ${addRes.statusText}`);
|
|
}
|
|
} else {
|
|
throw new Error(`${res.status} ${res.statusText}`);
|
|
}
|
|
};
|
|
```
|
|
|
|
A request to a user's log `GET /api/users/:_id/logs` returns a user object with a `count` property representing the number of exercises that belong to that user.
|
|
|
|
```js
|
|
async (getUserInput) => {
|
|
const url = getUserInput('url');
|
|
const res = await fetch(url + '/api/users', {
|
|
method: 'POST',
|
|
headers: { 'Content-Type': 'application/x-www-form-urlencoded' },
|
|
body: `username=fcc_test_${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}`);
|
|
}
|
|
};
|
|
```
|
|
|
|
A `GET` request to `/api/users/:id/logs` will return the user object with a `log` array of all the exercises added.
|
|
|
|
```js
|
|
async(getUserInput) => {
|
|
const url = getUserInput('url');
|
|
const res = await fetch(url + '/api/users', {

|

})
|
|
if(res.ok){
|
|
const {_id, username} = await res.json();
|
|
const expected = {
|

username,
|

description: 'test',
|
|
duration: 60,
|

_id,
|

date: new Date().toDateString()
|

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);
|

throw new Error(`${logRes.status} ${logRes.statusText}`);

|
};
|
|
} else {
|
|
throw new Error(`${res.status} ${res.statusText}`)
|
|
};
|
|
};
|
|
```
|
|
|
|
Each item in the `log` array that is returned from `GET /api/users/:id/logs` is an object that should have a `description`, `duration`, and `date` properties.
|
|
|
|
```js
|
|
async(getUserInput) => {
|
|
const url = getUserInput('url');
|

};
|
|
};
|
|
```
|
|
|
|
The `description` property of any object in the `log` array that is returned from `GET /api/users/:id/logs` should be a string.
|
|
|
|
```js
|
|
async(getUserInput) => {

|
|
};
|
|
```
|
|
|
|
The `duration` property of any object in the `log` array that is returned from `GET /api/users/:id/logs` should be a number.
|
|
|
|
```js
|
|
async(getUserInput) => {
|

const url = getUserInput('url');
|
|
const res = await fetch(url + '/api/users/', {

|
|
};
|
|
```
|
|
|
|
The `date` property of any object in the `log` array that is returned from `GET /api/users/:id/logs` should be a string.. Use the `dateString` format of the `Date` API.
|
|
|

You can add `from`, `to` and `limit` parameters to a `GET /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.
