{ title: {mandatory}, body: {mandatory}, authorId: {mandatory, refs to author model}, tags: {array of string}, category: {string, mandatory}, subcategory: {array of string, examples[technology-[web development, mobile development, AI, ML etc]] }, createdAt, updatedAt, deletedAt: {when the document is deleted}, isDeleted: {boolean, default: false}, publishedAt: {when the blog is published}, isPublished: {boolean, default: false}}

Author APIs /authors

• Create an author - atleast 5 authors
• Create a author document from request body. Endpoint: BASE_URL/authors

POST /blogs

• Create a blog document from request body. Get authorId in request body only.

• Make sure the authorId is a valid authorId by checking the author exist in the authors collection.

• Return HTTP status 201 on a succesful blog creation. Also return the blog document. The response should be a JSON object like this

• Create atleast 5 blogs for each author

• Return HTTP status 400 for an invalid request with a response body like this

GET /blogs

• Returns all blogs in the collection that aren't deleted and are published
• Return the HTTP status 200 if any documents are found. The response structure should be like this
• If no documents are found then return an HTTP status 404 with a response like this
• Filter blogs list by applying filters. Query param can have any combination of below filters.
  • By author Id
  • By category
  • List of blogs that have a specific tag
  • List of blogs that have a specific subcategory example of a query url: blogs?filtername=filtervalue&f2=fv2

PUT /blogs/:blogId

• Updates a blog by changing the its title, body, adding tags, adding a subcategory. (Assuming tag and subcategory received in body is need to be added)
• Updates a blog by changing its publish status i.e. adds publishedAt date and set published to true
• Check if the blogId exists (must have isDeleted false). If it doesn't, return an HTTP status 404 with a response body like this
• Return an HTTP status 200 if updated successfully with a body like this
• Also make sure in the response you return the updated blog document.

DELETE /blogs/:blogId

• Check if the blogId exists( and is not deleted). If it does, mark it deleted and return an HTTP status 200 without any response body.
• If the blog document doesn't exist then return an HTTP status of 404 with a body like this

DELETE /blogs?queryParams

• Delete blog documents by category, authorid, tag name, subcategory name, unpublished
• If the blog document doesn't exist then return an HTTP status of 404 with a body like this

Phase II

• Add authentication and authroisation feature

POST /login

• Allow an author to login with their email and password. On a successful login attempt return a JWT token contatining the authorId in response body like this
• If the credentials are incorrect return a suitable error message with a valid HTTP status code

Authentication

• Add an authorisation implementation for the JWT token that validates the token before every protected endpoint is called. If the validation fails, return a suitable error message with a corresponding HTTP status code
• Protected routes are create a blog, edit a blog, get the list of blogs, delete a blog(s)
• Set the token, once validated, in the request - x-api-key
• Use a middleware for authentication purpose.

Authorisation

• Make sure that only the owner of the blogs is able to edit or delete the blog.
• In case of unauthorized access return an appropirate error message.

Testing (Self-evaluation During Development)

• To test these apis create a new collection in Postman named Project 1 Blogging
• Each api should have a new request in this collection
• Each request in the collection should be rightly named. Eg Create author, Create blog, Get blogs etc
• Each member of each team should have their tests in running state
