# Contributing a new API to Node-API
|
|
|
|
Node-API is the next-generation ABI-stable API for native addons.
|
|
While improving the API surface is encouraged and welcomed, the following are
|
|
a set of principles and guidelines to keep in mind while adding a new
|
|
Node-API.
|
|
|
|
* A new API **must** adhere to Node-API API shape and spirit.
|
|
* **Must** be a C API.
|
|
* **Must** not throw exceptions.
|
|
* **Must** return `napi_status`.
|
|
* **Should** consume `napi_env`.
|
|
* **Must** operate only on primitive data types, pointers to primitive
|
|
data types or opaque handles.
|
|
* **Must** be a necessary API and not a nice to have. Convenience APIs
|
|
belong in node-addon-api.
|
|
* **Must** not change the signature of an existing Node-API API or break
|
|
ABI compatibility with other versions of Node.js.
|
|
* New API **should** be agnostic towards the underlying JavaScript VM.
|
|
* New API PRs **must** have a corresponding documentation update.
|
|
* New API PRs **must** be tagged as **node-api**.
|
|
* There **must** be at least one test case showing how to use the API.
|
|
* There **should** be at least one test case per interesting use of the API.
|
|
* There **should** be a sample provided that operates in a realistic way
|
|
(operating how a real addon would be written).
|
|
* A new API **should** be discussed at the Node-API team meeting.
|
|
* A new API addition **must** be signed off by at least two members of
|
|
the Node-API team.
|
|
* A new API addition **should** be simultaneously implemented in at least
|
|
one other VM implementation of Node.js.
|
|
* A new API **must** be considered experimental for at least one minor
|
|
version release of Node.js before it can be considered for promotion out
|
|
of experimental.
|
|
* Experimental APIs **must** be documented as such.
|
|
* Experimental APIs **must** require an explicit compile-time flag
|
|
(`#define`) to be set to opt-in.
|
|
* Experimental APIs **must** be considered for backport.
|
|
* Experimental status exit criteria **must** involve at least the
|
|
following:
|
|
* A new PR **must** be opened in `nodejs/node` to remove experimental
|
|
status. This PR **must** be tagged as **node-api** and **semver-minor**.
|
|
* Exiting an API from experimental **must** be signed off by the team.
|
|
* If a backport is merited, an API **must** have a down-level
|
|
implementation.
|
|
* The API **should** be used by a published real-world module. Use of
|
|
the API by a real-world published module will contribute favorably
|
|
to the decision to take an API out of experimental status.
|
|
* The API **must** be implemented in a Node.js implementation with an
|
|
alternate VM.
