## Description
|
|
|
|
<section id='description'>
|
|
Build a full stack JavaScript app that is functionally similar to this: <a href='https://file-metadata-microservice.freecodecamp.rocks/' target='_blank'>https://file-metadata-microservice.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-filemetadata/'>this GitHub repo</a> and complete your project locally.
|
|
- Use <a href='https://repl.it/github/freeCodeCamp/boilerplate-project-filemetadata' target='_blank'>our repl.it starter project</a> 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.

<section id='tests'>

|
```yml
|
|
tests:
|
|
- text: You should provide your own project, not the example URL.
|
|
testString: |
|
|
getUserInput => {
|
|
assert(!/.*\/file-metadata-microservice\.freecodecamp\.rocks/.test(getUserInput('url')));
|
|
}
|
|
- text: You can submit a form that includes a file upload.
|
|
testString: "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\"]'));
|
|
}"
|
|
- text: The form file input field has the `name` attribute set to `upfile`.
|
|
testString: "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\"]'));
|
|
}"
|
|
- text: When you submit a file, you receive the file `name`, `type`, and `size` in bytes within the JSON response.
|
|
testString: "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');
