Haigo

YeSQL-like abstraction layer for Mongo on Go

What is Haigo?

Haigo lets you write and use standard MongoDB queries directly from within your Go application.

Why?

While working on a project that leveraged Mongo's aggregation framework extensively, we found that writing complicated queries in Go was painful and brittle with deeply nested bson.M or map[string]interface{} clauses.

With Haigo, you can use the JSON formatted Mongo queries directly.

Usage

1. Connect to Mongo (as you would normally)

2. Load Query File: SEE examples/queries.yml for example query files.
   hf, err := haigo.LoadQueryFile("queries.yml")

3. Configure Haigo Params:
   params := haigo.Params{"name": "Ali", "age": 32}

4. Execute Query/Pipe:
   q, err := hf.Queries["FindUser"].Pipe(col, params)

5. Handle result (as you would normally):
   q.Count()

TODO

• Parse MongoDB Query YAML
• Detect Queries
• Replace Query Params
• Integrate CI
• More/Better Tests
• Better Error Handling
