# --description--
 | 
						|
 | 
						|
Build a full stack JavaScript app that is functionally similar to this: <https://file-metadata-microservice.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-filemetadata/) and complete your project locally.
 | 
						|
-   Use [our repl.it starter project](https://repl.it/github/freeCodeCamp/boilerplate-project-filemetadata) 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 projects source code in the `GitHub Link` field.
 | 
						|
 | 
						|
# --instructions--
 | 
						|
 | 
						|
**HINT:** You can use the `multer` npm package to handle file uploading.
 | 
						|
 | 
						|
# --hints--
 | 
						|
 | 
						|
You should provide your own project, not the example URL.
 | 
						|
 | 
						|
```js
 | 
						|
(getUserInput) => {
 | 
						|
  assert(
 | 
						|
    !/.*\/file-metadata-microservice\.freecodecamp\.rocks/.test(
 | 
						|
      getUserInput('url')
 | 
						|
    )
 | 
						|
  );
 | 
						|
};
 | 
						|
```
 | 
						|
 | 
						|
You can submit a form that includes a file upload.
 | 
						|
 | 
						|
```js
 | 
						|
async (getUserInput) => {
 | 
						|
  const site = await fetch(getUserInput('url'));
 | 
						|
  const data = await site.text();
 | 
						|
  const doc = new DOMParser().parseFromString(data, 'text/html');
 | 
						|
  assert(doc.querySelector('input[type="file"]'));
 | 
						|
};
 | 
						|
```
 | 
						|
 | 
						|
The form file input field has the `name` attribute set to `upfile`.
 | 
						|
 | 
						|
```js
 | 
						|
async (getUserInput) => {
 | 
						|
  const site = await fetch(getUserInput('url'));
 | 
						|
  const data = await site.text();
 | 
						|
  const doc = new DOMParser().parseFromString(data, 'text/html');
 | 
						|
  assert(doc.querySelector('input[name="upfile"]'));
 | 
						|
};
 | 
						|
```
 | 
						|
 | 
						|
When you submit a file, you receive the file `name`, `type`, and `size` in bytes within the JSON response.
 | 
						|
 | 
						|
```js
 | 
						|
async (getUserInput) => {
 | 
						|
  const formData = new FormData();
 | 
						|
  const fileData = await fetch(
 | 
						|
    'https://cdn.freecodecamp.org/weather-icons/01d.png'
 | 
						|
  );
 | 
						|
  const file = await fileData.blob();
 | 
						|
  formData.append('upfile', file, 'icon');
 | 
						|
  const data = await fetch(getUserInput('url') + '/api/fileanalyse', {
 | 
						|
    method: 'POST',
 | 
						|
    body: formData
 | 
						|
  });
 | 
						|
  const parsed = await data.json();
 | 
						|
  assert.property(parsed, 'size');
 | 
						|
  assert.equal(parsed.name, 'icon');
 | 
						|
  assert.equal(parsed.type, 'image/png');
 | 
						|
};
 | 
						|
```
 | 
						|
