⚡ What is Httli?

Httli is a fast, terminal-native HTTP client built in Go with zero external runtime dependencies. It goes beyond curl to give you a complete developer workflow — saved requests, environments, history, batch execution, and JSON extraction — all from your terminal.

# Fire a quick request
httli -u https://api.github.com/users/octocat

# POST with auth and body
httli -m POST -u https://api.example.com/login \
  -d '{"user":"admin","pass":"secret"}' \
  -b mytoken

# Save it, then run it in any environment
httli collection save auth/login -m POST -u {{BASE_URL}}/login -d '{"user":"admin"}'
httli collection run auth/login --env prod

# Run a whole test suite in CI
httli collection run-all auth/ --fail-fast --timeout 10s --format json

📁 Collections

Collections let you save, name, and replay HTTP requests — with full fidelity, including auth, timeouts, and headers.

Save and run

# Save a request (fails if name already exists)
httli collection save auth/login \
  -m POST \
  -u {{BASE_URL}}/auth/login \
  -d '{"user":"admin"}' \
  -b mytoken \
  --timeout 15s \
  --retry 2

# Add a description (shown in list)
httli collection describe auth/login "Authenticate and get session token"

# Update an existing request
httli collection update auth/login -b newtoken

# Run it
httli collection run auth/login --env prod

# Run with runtime overrides
httli collection run auth/login --timeout 5s --format json --verbose

List and inspect

httli collection list

Saved Requests:

  Ungrouped/
    - ping [GET https://api.example.com/ping]

  auth/
    - login [POST https://{{BASE_URL}}/auth/login]  # Authenticate and get session token
    - refresh [POST https://{{BASE_URL}}/auth/refresh]

What gets saved

Every field is persisted — nothing is silently dropped:

Field	Saved?
Method, URL	✅
Headers	✅
Body	✅
Bearer token	✅
Basic auth	✅
Timeout	✅ (stored as `"15s"`)
Follow redirects	✅
Retry count & delay	✅
Description	✅
Created / Updated timestamps	✅

Namespace grouping

Use / in the name to group requests:

httli collection save api/users/list   -m GET  -u {{BASE_URL}}/users
httli collection save api/users/create -m POST -u {{BASE_URL}}/users -d '{"name":"Bob"}'
httli collection save api/products     -m GET  -u {{BASE_URL}}/products

Batch execution (run-all)

# Run everything
httli collection run-all

# Run only the auth/ group
httli collection run-all auth/

# Stop immediately on first failure
httli collection run-all --fail-fast

# Apply runtime overrides to all
httli collection run-all --timeout 10s --retry 1 --format json

State chaining between requests — run-all automatically sets env vars after each step:

Variable	Value
`HTTLI_LAST_STATUS`	HTTP status code, e.g. `200`
`HTTLI_LAST_BODY_PATH`	Absolute path to temp file with raw body
`HTTLI_LAST_JSON`	Raw JSON body string (if ≤ 32KB, valid JSON)

Use {{HTTLI_LAST_JSON}} in a subsequent request body to chain results:

httli collection save api/order -m POST -u {{BASE_URL}}/order \
  -d '{"token":"{{HTTLI_LAST_JSON}}"}'

Export and Import

# Export all collections to file
httli collection export my-api.json

# Import (3 modes)
httli collection import my-api.json              # merge (default) — add new, skip conflicts
httli collection import my-api.json --overwrite  # replace all existing with imported

Tip: Create a .httli/ directory in your project root to scope collections to that project. Commit .httli/ to share collections with your team alongside your code.

🌍 Environments

Use {{VAR}} placeholders anywhere — URLs, headers, body, auth — and substitute them with .env files.

.env file format

BASE_URL=https://api.example.com
API_TOKEN=secret123
DB_USER=admin

Loading order (highest priority last)

.env            → base defaults (committed, shared)
.env.local      → local overrides (git-ignored, personal)
.env.<name>     → activated via --env flag (e.g., .env.prod)

Safe for CI/CD: Httli never overwrites an environment variable that already exists in the shell. Your CI platform's secrets always win.

Usage

# Use base .env only
httli -u {{BASE_URL}}/users -b {{API_TOKEN}}

# Activate a specific environment
httli collection run auth/login --env prod   # loads .env + .env.local + .env.prod
httli collection run auth/login --env staging

View loaded variables

httli env list

Active Environment: prod

Loaded files (in order):
  ✓ .env
  ✓ .env.local
  ✓ .env.prod
  ✗ (no other files)

Chaining Variables:
  HTTLI_LAST_STATUS = 200

All Environment Variables:
  API_TOKEN = secret123
  BASE_URL = https://api.example.com

Missing variable behavior

# Strict mode (default) — errors on unresolved {{VAR}}
httli -u {{MISSING_VAR}}/api
# Error: environment variable 'MISSING_VAR' not found

# Permissive mode — leaves placeholder as-is
httli -u {{MISSING_VAR}}/api --ignore-missing-env

📊 History

Every executed request is automatically recorded. The last 50 entries are kept.

# View history with status and duration
httli history

Request History:
  [1] ✓ GET https://api.example.com/users → 200 (124ms)  2026-04-01T01:00:00+05:30
  [2] ✗ POST https://api.example.com/login → 401 (89ms)  2026-04-01T01:01:00+05:30
  [3] ✓ GET https://jsonplaceholder.typicode.com/posts/1 → 200 (287ms)  2026-04-01T01:02:00+05:30

# Inspect a full entry (method, URL, headers, body, auth, duration)
httli history show 1

# Re-run entry #1 with overrides — full fidelity (headers, body, auth restored)
httli rerun 1
httli rerun 1 --timeout 5s --format json --verbose

# Clear all history
httli history clear

Full-fidelity rerun: rerun restores the complete original request — method, URL, headers, body, bearer token, and basic auth — not just the URL.

🤖 Scripting & CI

Httli is designed for headless use in scripts and pipelines.

Exit codes

Code	Meaning
`0`	Success
`1`	Usage error / network error
`22`	HTTP 4xx/5xx (when `--fail` is set)

JSON output pipeline

# Structured JSON output to pipe to jq
httli -u https://api.example.com/users --format json | jq '.body.users[0].name'

# Native extraction (no jq needed)
httli -u https://api.example.com/data --extract .items[0].id

# Dot-notation supports arrays
httli -u https://api.example.com/data --extract .data.users[0].email

Stdin as request body

cat payload.json | httli -m POST -u https://api.example.com/ingest -d @-

Silent mode for scripts

# Script only cares about exit code
httli -u https://api.example.com/health --fail --silent
if [ $? -eq 0 ]; then echo "API is up"; fi

# Just print status code
STATUS=$(httli -u https://api.example.com/health --status-only)
echo "Got: $STATUS"

Dry run

# See the fully resolved request (env vars substituted) without firing it
httli -m POST -u {{BASE_URL}}/login -d '{"user":"admin"}' --env prod --dry-run

Retry strategies

# Fixed delay retry (default)
httli -u https://api.example.com/data --retry 3 --retry-delay 5

# Exponential backoff (2s, 4s, 8s... capped at 30s)
httli -u https://api.example.com/data --retry 4 --retry-delay 2 --retry-backoff

# Verbose retry output to stderr (won't pollute stdout)
httli -u https://api.example.com/data --retry 2 --verbose
# → Retry 1/2 in 2s (HTTP 503)
# → Retry 2/2 in 2s (HTTP 503)

CI/CD example

#!/bin/bash
# Run full API test suite, fail on first error, timeout per request, exit 22 on any 4xx/5xx
httli collection run-all smoke-tests/ \
  --env ci \
  --fail-fast \
  --fail \
  --timeout 10s \
  --retry 1 \
  --format json \
  --silent

Save response to file

# --output works with ALL display modes (raw, silent, status-only)
httli -u https://api.example.com/report --output report.json --silent
httli -u https://api.example.com/report --output report.json --raw

Request lifecycle

httli -m POST -u {{BASE_URL}}/login -d '{"user":"admin"}' --env prod
         │
         ▼
1. ParseFlags()          — parse all CLI flags into Config struct
         │
         ▼
2. LoadEnv(prod)         — load .env, .env.local, .env.prod
         │                 (never overwrites existing shell vars)
         ▼
3. InterpolateAll()      — replace {{BASE_URL}} with env var value
         │                 (errors on missing vars unless --ignore-missing-env)
         ▼
4. Validate()            — ensure URL is present, format is valid
         │
         ▼
5. [dry-run check]       — if --dry-run, print request and exit
         │
         ▼
6. ExecuteRequest()      — make HTTP call
         │                 add Auth headers (bearer → Authorization: Bearer ...)
         │                 JSON body validation
         │                 retry loop (with optional exponential backoff)
         │                 5xx body always captured before retry
         │                 verbose retry logging to stderr
         ▼
7. history.Record()      — save full request + response metadata to history
         │
         ▼
8. DisplayResponse()     — render output:
                           --output saves file first (orthogonal to display mode)
                           then: extract → format json → raw → status-only → quiet → full pretty

Storage locations

Httli uses project-local storage when a .httli/ directory is detected in the current working directory. Otherwise it falls back to a global directory.

Platform	Global path
Windows	`%APPDATA%\httli\`
macOS	`~/Library/Application Support/httli/`
Linux	`~/.config/httli/`

File	Contents
`collections.json`	All saved requests
`history.json`	Last 50 executed requests

Flag system internals

ParseFlags() uses flag.ContinueOnError — unknown flags return errors instead of calling os.Exit
All flags have both short (-m) and long (--method) forms registered in the same FlagSet
InterpolateAll() is not called in ParseFlags() — callers invoke it explicitly, preventing double-substitution when collection run or rerun call it after loading the saved config
ApplyOverrides(runCfg) merges runtime CLI flags onto a loaded collection config — timeout is only overridden if the user explicitly set a non-default value

The `{{VAR}}` interpolation system

Placeholders are matched by the regex \{\{\s*([A-Za-z0-9_]+)\s*\}\} (compiled once at package level). The regex supports optional whitespace ({{ VAR }} or {{VAR}}). Interpolation runs across: URL, body, bearer token, basic auth, and all header values.

Retry logic

attempt 1  → request → 5xx or network error → read body → save lastResp
attempt 2  → sleep(delay) → request → ...
attempt N  → sleep(delay) → request → 5xx → return lastResp (NOT an error)

# with --retry-backoff:
delay formula: baseDelay × 2^attempt, capped at 30s
attempt 1: 2s, attempt 2: 4s, attempt 3: 8s, attempt 4: 16s, attempt 5+: 30s

On the final attempt, the 5xx Response is returned (not an error) so callers can inspect resp.StatusCode and resp.Body — enabling --fail exit code logic and run-all summary tables to work correctly with server error details.

Contributions are welcome! See CONTRIBUTING.md for guidelines.

Running tests

go test ./...
go vet ./...

Project conventions

All new features belong in internal/ — keep cmd/ as a thin dispatch layer
ParseFlags() must not call InterpolateAll() — callers do this explicitly
New config fields go in Config struct with both short+long flag registration
Exported functions in internal/ packages take *config.Config, not individual params
