Golang Echo blogging platform

Technologies

Description

A group of snippet projects made with Golang, Echo framework, and multiple libraries and databases (SQL and NoSQL) providing an API backend allowing users to register, login, and write posts and comments.

Each of these projects is Dockerized with the multi-stage build and unprivileged user execution in the final image. In the future addition of Kubernetes Helm charts is planned and another flavors with Cassandra and Scylla is planned.

To run a single project, execute docker-compose up in the project directory and go to http://127.0.0.1:1323/. Swagger with API reference will be available at http://127.0.0.1:1323/swagger/index.html. Prometheus metrics will be accessible at http://127.0.0.1:1323/metrics.

Authorization

Most of the endpoints require an authorization with HTTP bearer token with the prefix Bearer<space>. To obtain the token, issue a POST request to /token endpoint with form-encoded values of user's name and password gathered by creating the user with POST request to /user endpoint. An example of these transactions has been shown in the API reference in 999 directory.

Versions

• 001_postgres_and_redis – Version with PostgreSQL database used to store users, posts, and comments and Redis used to store session data. The authentication is done with Bearer Tokens. Swagger and Prometheus are available.

• 002_mysql_and_redis – Almost the same as described above but with the use of MySQL instead of PostgreSQL.

• 003_MONGO_and_redis – The same as above but with MongoDB used to store content.

• 999_memory – Basic version with no real database. The data are stored in RAM during the execution of the program. This can not be scaled. The API is "documented" in api_reference.md as there is no Swagger. Also, there is no Prometheus included. This is the version that any other one described above is based on. The authentication is done with Bearer Tokens.

TODO

• Write tests
• Add Helm charts
• Add Cassandra and Scylla flavours
