go-onlyoffice

Go client library for the OnlyOffice Project Management API — manage projects, tasks, subtasks, milestones, and users programmatically.

Pairs with go-gitea-helpers to bridge developer issue trackers with CRM-grade project management for Gantt charts, resource planning, and executive reporting.

Without sync: Project managers manually copy issue titles, deadlines, and status from Gitea into OnlyOffice. Developers don't update the CRM. Gantt charts rot. Reports lie.

With sync: Issues flow automatically from Gitea to OnlyOffice with start dates, deadlines, and status. PMs get live Gantt charts. Developers keep working in Git.

Installation

go get github.com/eslider/go-onlyoffice

For Gitea sync (optional):

go get github.com/eslider/go-gitea-helpers

Quick Start

Connect and List Projects

client := onlyoffice.NewClient(onlyoffice.GetEnvironmentCredentials())

projects, _ := client.GetProjects()
for _, p := range projects {
    fmt.Printf("[%d] %s — %d tasks\n", *p.ID, *p.Title, safeInt(p.TaskCountTotal))
}

Create a Project with Tasks and Deadlines

// Create a project
project, _ := client.CreateProject(onlyoffice.NewProjectRequest{
    Title:       "Q1 2026 Release",
    Description: "Backend API v2 + mobile app redesign",
})

// Create tasks with start/end dates (for Gantt chart)
client.CreateProjectTask(onlyoffice.NewProjectTaskRequest{
    ProjectId:   *project.ID,
    Title:       "Design API schema",
    Description: "OpenAPI 3.1 spec for all endpoints",
    StartDate:   onlyoffice.Time(time.Now()),
    Deadline:    onlyoffice.Time(time.Now().AddDate(0, 0, 14)),
    Priority:    1, // High
})

client.CreateProjectTask(onlyoffice.NewProjectTaskRequest{
    ProjectId:   *project.ID,
    Title:       "Implement auth service",
    Description: "JWT + OAuth2 + refresh tokens",
    StartDate:   onlyoffice.Time(time.Now().AddDate(0, 0, 14)),
    Deadline:    onlyoffice.Time(time.Now().AddDate(0, 1, 0)),
})

List and Filter Tasks

// Get all tasks for a project
tasks, _ := client.GetTasks(onlyoffice.NewProjectGetTasksRequest(*project.ID))

for _, t := range tasks {
    status := "open"
    if t.Status != nil && *t.Status == onlyoffice.ProjectTaskStatusClosed {
        status = "closed"
    }
    fmt.Printf("  [%s] %s", status, *t.Title)
    if t.Deadline != nil {
        fmt.Printf(" (due: %s)", t.Deadline.Format("2006-01-02"))
    }
    fmt.Println()
}

Update Task Status and Dates

// Close a task and set actual end date
client.UpdateProjectTask(onlyoffice.ProjectTaskUpdateRequest{
    ID:       taskID,
    Title:    "Design API schema",
    Status:   onlyoffice.ProjectTaskStatusClosed,
    Deadline: &onlyoffice.Time(time.Now()),
})

Get Milestones and Task Progress

milestones, _ := client.GetProjectMilestones(project)
for _, ms := range milestones {
    active := int64(0)
    closed := int64(0)
    if ms.ActiveTaskCount != nil { active = *ms.ActiveTaskCount }
    if ms.ClosedTaskCount != nil { closed = *ms.ClosedTaskCount }
    total := active + closed

    fmt.Printf("Milestone: %s — %d/%d tasks done", *ms.Title, closed, total)
    if ms.Deadline != nil {
        fmt.Printf(" (deadline: %s)", ms.Deadline.Format("2006-01-02"))
    }
    fmt.Println()
}

Use Case: Gitea → OnlyOffice Sync

The primary use case is bridging developer workflows with project management. Developers create issues in Gitea; a sync job automatically mirrors them as OnlyOffice tasks with proper start/end dates, enabling PMs to work with Gantt charts without developers leaving their Git workflow.

Sync Flow

sequenceDiagram
    participant Dev as Developer
    participant Gitea
    participant Sync as Sync Job
    participant OO as OnlyOffice

    Dev->>Gitea: Create issue "Add OAuth2"
    Note over Gitea: issue.Created = Feb 13<br/>issue.Deadline = Mar 1

    Sync->>Gitea: GET /repos/{org}/*/issues
    Gitea-->>Sync: issues list (paginated)

    Sync->>OO: GET /api/2.0/project/filter.json
    OO-->>Sync: projects list

    Sync->>Sync: Match Gitea labels → OO projects

    alt Issue not yet in OnlyOffice
        Sync->>OO: POST /api/2.0/project/{id}/task.json
        Note over OO: Task created:<br/>Start: Feb 13, End: Mar 1<br/>Description includes Gitea URL
    else Issue already synced
        Sync->>OO: PUT /api/2.0/project/task/{id}.json
        Note over OO: Title, status, dates updated
    end

    Dev->>Gitea: Close issue "Add OAuth2"
    Sync->>OO: PUT status → Closed
    Note over OO: Gantt chart updates automatically

What Project Managers Get

Once synced, OnlyOffice provides without any developer intervention:

Feature	How It Works
Gantt Charts	Tasks have StartDate and Deadline from Gitea issue created/due dates
Status Tracking	Open/closed status mirrors Gitea issue state in real time
Milestone Planning	Gitea milestones map to OnlyOffice milestones with progress %
Resource Allocation	Task assignees sync so PMs see who's working on what
Sprint Reports	Filter by date range to generate sprint/release reports
Cross-Repo View	All repos' issues appear as tasks in a unified project board
Executive Dashboards	Project progress, overdue tasks, team workload at a glance

Use Case: Task Lifecycle Management

Creating Tasks with Full Metadata

task, _ := client.CreateProjectTask(onlyoffice.NewProjectTaskRequest{
    ProjectId:   projectID,
    Title:       "Implement payment gateway",
    Description: "Integrate Stripe API for subscription billing",
    StartDate:   onlyoffice.Time(time.Date(2026, 3, 1, 0, 0, 0, 0, time.UTC)),
    Deadline:    onlyoffice.Time(time.Date(2026, 3, 15, 0, 0, 0, 0, time.UTC)),
    Priority:    1, // High
    MilestoneId: milestoneID,
    Notify:      true,
})

Tracking Task Progress

tasks, _ := client.GetTasks(onlyoffice.NewProjectGetTasksRequest(projectID))

open, closed := 0, 0
var overdue []*onlyoffice.Task

for _, t := range tasks {
    if t.Status != nil && *t.Status == onlyoffice.ProjectTaskStatusClosed {
        closed++
    } else {
        open++
        if t.Deadline != nil && t.Deadline.Before(time.Now()) {
            overdue = append(overdue, t)
        }
    }
}

fmt.Printf("Progress: %d/%d done (%.0f%%)\n", closed, open+closed,
    float64(closed)/float64(open+closed)*100)

if len(overdue) > 0 {
    fmt.Printf("⚠ %d overdue tasks:\n", len(overdue))
    for _, t := range overdue {
        fmt.Printf("  - %s (due: %s)\n", *t.Title, t.Deadline.Format("2006-01-02"))
    }
}

Subtask Management

Tasks support subtasks for breaking work into smaller pieces:

type Task struct {
    ID           *int          `json:"id"`
    Title        *string       `json:"title"`
    StartDate    *time.Time    `json:"startDate"`
    Deadline     *time.Time    `json:"deadline"`
    Description  *string       `json:"description"`
    Priority     *int          `json:"priority"`       // High=1, Normal=0, Low=-1
    Status       *ProjectTaskStatus `json:"status"`    // Open=1, Closed=2
    Subtasks     []any         `json:"subtasks"`
    MilestoneID  *int64        `json:"milestoneId"`
    Responsibles []*User       `json:"responsibles"`   // Assigned team members
    // ... timestamps, permissions
}

Calendar, CRM, Subtasks, File upload (v0.2+)

Since v0.2 the library also exposes OnlyOffice Workspace surfaces beyond Projects: Calendar events, CRM (Contacts, Companies, Opportunities, Cases, Tasks, History notes) and opportunity file uploads. These helpers return untyped map[string]any for flexibility; callers that need typed structs should use the typed Project/Task API above.

client := onlyoffice.NewClient(onlyoffice.GetEnvironmentCredentials())
client.SetDefaults(onlyoffice.GetEnvironmentDefaults()) // optional
ctx := context.Background()

// Calendar
events, _ := client.ListEvents(ctx, "2025-01-01", "2025-12-31")
client.AddEvent(ctx, "", "Interview", "2025-06-10T10:00:00Z", "2025-06-10T11:00:00Z", "", false)

// CRM
deals, total, _ := client.ListOpportunities(ctx, 50, 0)
company, _ := client.FindCompany(ctx, "ACME")

// Subtasks (form-encoded)
client.AddSubtask(ctx, "4242", "Prepare CV")

oo (bundled command)

A ready-to-use Cobra CLI wrapping the library lives under cmd/oo. The command tree is subject-based, mirroring the tea CLI:

go install github.com/eslider/go-onlyoffice/cmd/oo@latest

# Global: every list-style command takes -o table|json (default: table)
oo whoami
oo users list
oo calendar events --start 2026-04-24 --end 2026-05-01
oo projects list
oo projects get 33
oo tasks list --all --verbose
oo tasks subtask add 4242 "Prepare CV"
oo persons create --first Jane --last Doe --email jane@example.com
oo companies create --name "Acme GmbH" --website https://acme.com
oo opportunities list
oo opportunities stages
oo cases list
oo crm-tasks categories
oo applications sync --path ./applications/2026 --apply

# Project Documents (files module)
oo projects files list 33
oo projects files upload 33 ./notes.md
oo projects files download 12345 --to ./copy.md
oo projects files rename 12345 notes-v2.md
oo projects files delete 12345
oo tasks files list 208
oo tasks files upload 208 ./cv.pdf
oo tasks files detach 208 12345

Subject	Verbs
calendar	list, events, add, delete
projects	list, get, milestones, create, update, delete, files (list, upload, download, rename, delete)
tasks	list, get, create, update, delete, subtask add, files (list, upload, detach)
users	list, self (alias: oo whoami)
contacts	list, get, delete, info-add
persons	list (filtered), create, delete
companies	list (filtered), create, delete
opportunities	list, get, create, delete, stages, member-add
cases	list, create, delete, member-add
crm-tasks	list, create, delete, categories
applications	sync

The CLI reads .env from CWD (godotenv is a CLI-only concern — the library itself never loads dotfiles). Run oo --help or oo <subject> --help for the full command reference.

0.5.0 migration note: the command tree was flattened per-subject. Old flat names (oo cal-events, oo task-list, oo crm-contacts, oo applications-sync, …) were replaced by subject-based equivalents (oo calendar events, oo tasks list, oo contacts list, oo applications sync). Flags on leaf commands are unchanged.

Environment Variables

Variable	Description
ONLYOFFICE_URL (or ONLYOFFICE_HOST)	OnlyOffice instance URL
ONLYOFFICE_USER (or ONLYOFFICE_NAME)	Login email or username
ONLYOFFICE_PASS (or ONLYOFFICE_PASSWORD)	Password
ONLYOFFICE_CALENDAR_ID	Default calendar id used when omitted (default 1)
ONLYOFFICE_PROJECT_ID	Default project id used when omitted (default 33)
