Bytebase is a database DevSecOps platform designed for developers, security, DBA, and platform engineering teams. While it offers an intuitive GUI for managing database schema changes and access control, some teams may want to integrate Bytebase into their existing DevOps platforms using the Bytebase API. before-after In our previous tutorials, we demonstrated how to use the Bytebase API to:
  1. Create a schema change
  2. Check user and database permissions
This tutorial will focus on fetch and filter audit log in Bytebase, it’s OK if you haven’t gone through the previous tutorials.

​
Repository

https://github.com/bytebase/example-api/tree/main/audit-log

​
Prerequisites

  1. Docker installed
  2. Node.js >= v18

​
Start Bytebase

Make sure your Docker daemon is running. Copy and paste the commands to start Bytebase. 
docker run --rm --init \
  --name bytebase \
  --publish 8080:8080 --pull always \
  --volume ~/.bytebase/data:/var/opt/bytebase \
  bytebase/bytebase:3.8.1
Bytebase is now running via Docker, and you can access it via localhost:8080. Register the first admin account which will be granted Workspace Admin.

​
Create Service Account

  1. Log in as Workspace Admin, and go to IAM & Admin > Users & Groups. Click + Add User, fill in with api-sample, choose the Workspace DBA role sufficient for this tutorial and click Confirm. service-account-create
  2. Find the newly created service account and Copy Service Key. We will use this token to authenticate the API calls. service-account-key

​
Run Demo

  1. Go to Bytebase API Example repo and clone it.
  2. Copy env-template.local to .env.local.Update the variables.
    • NEXT_PUBLIC_BB_URL: http://localhost:8080
    • NEXT_PUBLIC_BB_SERVICE_ACCOUNT: api-example
    • NEXT_PUBLIC_BB_SERVICE_KEY: service key copied in previous step
  3. Go to subfolder audit-log, and run the following commands to start the demo application. 
    pnpm i && pnpm dev
  4. Open the demo in your browser, you’ll see the following page. api-audit-log-demo
  5. To enhance the demo’s realism, go to Bytebase:
    • Go to SQL Editor to query the database
    • Go to a specific project and do some database changes, e.g. create a database, create a table, add some data.

​
Fetch and Filter Audit Log

Let’s dig into the code:
  1. In page.tsx, we fetch all projects by calling the /v1/projects API before any project selection.
  2. Bytebase has two levels of audit log: Workspace and Project. When the user first visit the demo, We fetch Workspace-level audit log via /v1/auditLogs:search API. The default time range is 7 days back till now. You may also adjust the time range by passing startTime and endTime in the request body via filter. 
    const filter = `create_time >= '${startDate}' && create_time <= '${endDate}'`;
  3. In db-fetch-user-permission.tsx, if the user select a speicifc project, we fetch the project-level audit log via /v1/projects/PROJECT_ID/auditLogs:search​ API. The time range filter is the same as the workspace-level audit log.

​
Summary

Congratulations! You’ve successfully created a database audit viewer using the Bytebase API. Similarly, you may export the log by calling /v1/auditLogs:export API.
