# Building Node with Ninja
|
||
|
|
|
||
|
|
The purpose of this guide is to show how to build Node.js using [Ninja][], as doing so can be significantly quicker than using `make`. Please see [Ninja's site][Ninja] for installation instructions (unix only).
|
||
|
|
|
||
|
|
To build Node with ninja, there are 4 steps that must be taken:
|
||
|
|
|
||
|
|
1. Configure the project's OS-based build rules via `./configure` as usual.
|
||
|
|
2. Use `tools/gyp_node.py -f ninja` to produce Ninja-buildable `gyp` output.
|
||
|
|
3. Run `ninja -C out/Release` to produce a compiled release binary.
|
||
|
|
4. Lastly, make symlink to `./node` using `ln -fs out/Release/node node`.
|
||
|
|
|
||
|
|
When running `ninja -C out/Release` you will see output similar to the following if the build has succeeded:
|
||
|
|
```
|
||
|
|
ninja: Entering directory `out/Release`
|
||
|
|
[4/4] LINK node, POSTBUILDS
|
||
|
|
```
|
||
|
|
|
||
|
|
The bottom line will change while building, showing the progress as `[finished/total]` build steps.
|
||
|
|
This is useful output that `make` does not produce and is one of the benefits of using Ninja.
|
||
|
|
Also, Ninja will likely compile much faster than even `make -j8` (or `-j<number of processor threads on your machine>`).
|
||
|
|
|
||
|
|
## Considerations
|
||
|
|
|
||
|
|
Ninja builds vary slightly from `make` builds. If you wish to run `make test` after, `make` will likely still need to rebuild some amount of Node.
|
||
|
|
|
||
|
|
As such, if you wish to run the tests, it can be helpful to invoke the test runner directly, like so:
|
||
|
|
`tools/test.py --mode=release message parallel sequential -J`
|
||
|
|
|
||
|
|
## Alias
|
||
|
|
|
||
|
|
`alias nnode='./configure && tools/gyp_node.py -f ninja && ninja -C out/Release && ln -fs out/Release/node node'`
|
||
|
|
|
||
|
|
## Producing a debug build
|
||
|
|
|
||
|
|
The above alias can be modified slightly to produce a debug build, rather than a release build as shown below:
|
||
|
|
`alias nnodedebug='./configure && tools/gyp_node.py -f ninja && ninja -C out/Debug && ln -fs out/Debug/node node_g'`
