AppSignal has framework integrations for
AppSignal will automatically monitor requests, report any exceptions that are
thrown and any performance issues that might have occurred.
You can also add extra information to requests by adding custom

Before you can start developing on the AppSignal for Elixir project make sure
you have [Elixir installed](http://elixir-lang.org/install.html).
This repository is managed by [mono](https://github.com/appsignal/mono/).
Install mono on your local machine by [following the mono installation
Then make sure you have all the project's dependencies installed by running the
$ mono bootstrap
Testing is done with ExUnit and can be run with the `mix test` command. You can
also supply a path to a specific file path you want to test and even a specific
line on which the test you want to run is defined.
$ mono test
# The original command can still be used
$ mix test
$ mix test test/appsignal/some_test.ex:123
This project has several different test suites defined with different mix
environments. You can run them by specifying the specific type of test suite in
the `MIX_ENV` environment variable.
$ MIX_ENV=test mix test
# Run the test suite with the NIF inoperational. This will generate errors
# because the NIF is not active, but should run without failures.
$ MIX_ENV=test_no_nif mix test
This package uses benchee to benchmark code. To run the benchmarker:
$ MIX_ENV=bench mix run bench/<file>.exs
### Branches and versions
The `main` branch corresponds to the current release of the
library. The `develop` branch is used for development of features that
will end up in the next minor release. If you fix a bug open a pull
request on `main`, if it's a new feature on `develop`.
### Making changes
When making changes to the project that require a release, [add a
changeset](https://github.com/appsignal/mono/#changeset-add) that will be used
to update the generated `CHANGELOG.md` file upon
$ mono changeset add
### Publishing new versions
