Step by Step Guide to Building a Coda API Integration in Go

Introduction

Hey there, fellow developer! Ready to dive into the world of Coda API integration using Go? You're in for a treat. Coda's API is a powerhouse, and Go's simplicity and performance make it the perfect dance partner. Let's get this party started!

Prerequisites

Before we jump in, make sure you've got:

• Go installed (I know you probably do, but just checking!)
• A Coda API key (grab one from your Coda account if you haven't already)
• Your favorite code editor at the ready

Setting up the project

Let's kick things off by creating a new Go module:

mkdir coda-api-integration
cd coda-api-integration
go mod init github.com/yourusername/coda-api-integration

Now, let's grab the Coda API client:

go get github.com/coda/coda-go-client

Authenticating with the Coda API

Time to make friends with the Coda API. First, let's set up our client:

import (
    "github.com/coda/coda-go-client"
)

func main() {
    client := coda.NewClient("YOUR_API_KEY")
    // Now we're cooking with gas!
}

Basic API operations

Let's start with something simple - fetching a list of docs:

docs, err := client.ListDocs(nil)
if err != nil {
    log.Fatalf("Error fetching docs: %v", err)
}
for _, doc := range docs.Docs {
    fmt.Printf("Doc: %s\n", doc.Name)
}

Easy peasy, right? Now, let's grab a specific doc:

doc, err := client.GetDoc("YOUR_DOC_ID")
if err != nil {
    log.Fatalf("Error fetching doc: %v", err)
}
fmt.Printf("Got doc: %s\n", doc.Name)

Working with tables

Tables are where the real fun begins. Let's list the tables in a doc:

tables, err := client.ListTables("YOUR_DOC_ID", nil)
if err != nil {
    log.Fatalf("Error listing tables: %v", err)
}
for _, table := range tables.Tables {
    fmt.Printf("Table: %s\n", table.Name)
}

Now, let's fetch some table data:

rows, err := client.ListTableRows("YOUR_DOC_ID", "YOUR_TABLE_ID", nil)
if err != nil {
    log.Fatalf("Error fetching rows: %v", err)
}
for _, row := range rows.Rows {
    fmt.Printf("Row: %v\n", row.Values)
}

Manipulating data

Time to shake things up! Let's add a row to a table:

newRow := &coda.Row{
    Cells: []coda.Cell{
        {Column: "Name", Value: "John Doe"},
        {Column: "Age", Value: 30},
    },
}
addedRow, err := client.InsertRow("YOUR_DOC_ID", "YOUR_TABLE_ID", newRow)
if err != nil {
    log.Fatalf("Error adding row: %v", err)
}
fmt.Printf("Added row: %v\n", addedRow)

Updating is just as easy:

updatedRow := &coda.Row{
    Cells: []coda.Cell{
        {Column: "Age", Value: 31},
    },
}
updatedRow, err := client.UpdateRow("YOUR_DOC_ID", "YOUR_TABLE_ID", "ROW_ID", updatedRow)
if err != nil {
    log.Fatalf("Error updating row: %v", err)
}
fmt.Printf("Updated row: %v\n", updatedRow)

And if you're feeling destructive, here's how to delete a row:

err := client.DeleteRow("YOUR_DOC_ID", "YOUR_TABLE_ID", "ROW_ID")
if err != nil {
    log.Fatalf("Error deleting row: %v", err)
}
fmt.Println("Row deleted successfully")

Advanced features

Want to get fancy with formulas? Here's how:

formula := "=TODAY()"
result, err := client.EvaluateFormula("YOUR_DOC_ID", formula, nil)
if err != nil {
    log.Fatalf("Error evaluating formula: %v", err)
}
fmt.Printf("Formula result: %v\n", result.Result)

Error handling and best practices

Remember, the API has rate limits. Be a good citizen and implement retries:

func retryableRequest(f func() error) error {
    maxRetries := 3
    for i := 0; i < maxRetries; i++ {
        err := f()
        if err == nil {
            return nil
        }
        if apiErr, ok := err.(*coda.APIError); ok && apiErr.StatusCode == 429 {
            time.Sleep(time.Second * time.Duration(1<<uint(i)))
            continue
        }
        return err
    }
    return fmt.Errorf("max retries exceeded")
}

Testing the integration

Don't forget to test! Here's a quick example:

func TestListDocs(t *testing.T) {
    client := coda.NewClient("YOUR_API_KEY")
    docs, err := client.ListDocs(nil)
    if err != nil {
        t.Fatalf("Error listing docs: %v", err)
    }
    if len(docs.Docs) == 0 {
        t.Fatalf("Expected at least one doc, got none")
    }
}

Conclusion

And there you have it! You're now armed and dangerous with Coda API integration skills in Go. Remember, this is just scratching the surface - there's so much more you can do. Check out the Coda API documentation for more advanced features and keep building awesome stuff!

Now go forth and code, you magnificent developer, you!
