This commit makes the minimum changes necessary to run the project on modern Elixir (1.14+) and Erlang (25+). Changes: - Update Elixir requirement from ~> 1.7.2 to ~> 1.14 - Update HTTPoison from >= 1.2.0 to ~> 2.0 (fixes Hackney compatibility) - Update Credo from ~> 0.10.0 to ~> 1.7 (was crashing on Elixir 1.14) - Update ExDoc from >= 0.0.0 to ~> 0.31 (Earmark was crashing) - Add runtime: false to dev/test dependencies (modern best practice) - Update test expectations to match current Expo API error format All tests pass: mix format, compile, credo, docs, and test suite.
Poison has been abandoned since 2017. Jason is the modern, actively
maintained standard for JSON in Elixir with better performance.
Changes:
- Replace {:poison, "~> 3.1.0"} with {:jason, "~> 1.4"} in deps
- Replace all Poison.encode!/encode calls with Jason.encode!/encode
- Replace all Poison.decode calls with Jason.decode
- Update application list to use :jason instead of :poison
- Update module documentation references
Note: HTTPoison still depends on Poison internally, which is fine.
We've removed all direct usage from our codebase.
All tests pass.
Since Elixir 1.4, applications are automatically inferred from the deps list. The `applications` key is deprecated in favor of `extra_applications` which should only list built-in OTP apps (not dependencies). Changes: - Replace `applications: [:logger, :httpoison, :jason]` with `extra_applications: [:logger]` - :httpoison and :jason are now auto-started from deps - Only :logger remains as it's a built-in OTP application This follows modern Elixir conventions and removes deprecation warnings. All tests pass.
These dependencies are no longer maintained or useful: - dialyze (last updated 2017): Outdated Dialyzer wrapper. Modern Elixir projects use the built-in `mix dialyzer` or the actively maintained `dialyxir` package if needed. - inch_ex: Documentation quality checker for the Inch CI service, which shut down years ago. No longer functional. Removing these reduces maintenance burden and dependency bloat. All tests pass.
Remove outdated Elixir 1.3 patterns from the installation guide. The old pattern was necessary 7+ years ago but confuses modern users.
