The provided `meson.build` can also be used as an alternative to CMake for installing `nlohmann_json` system-wide in
|
||||
which case a [pkg-config](pkg-config.md) file is installed. To use it, have your build system require the
|
||||
`nlohmann_json` pkg-config dependency. In Meson, it is preferred to use the
|
||||
[`dependency()`](https://mesonbuild.com/Reference-manual.html#dependency) object with a subproject fallback, rather than
|
||||
using the subproject directly.
|
||||
which case a [pkg-config](pkg-config.md) file and the CMake package config files are installed. To use it, have your build system require
|
||||
the `nlohmann_json` pkg-config dependency, or use [`find_package(nlohmann_json)`](cmake.md#external) in CMake. In Meson,
|
||||
it is preferred to use the [`dependency()`](https://mesonbuild.com/Reference-manual.html#dependency) object with a
|

subproject fallback, rather than using the subproject directly.
|
||||
|
||||
The options that change the library's configuration are available in Meson as well, named like the
|
||||
[CMake options](cmake.md#cmake-options) without the `JSON_` prefix: `MultipleHeaders`, `GlobalUDLs`,
|
||||
`ImplicitConversions`, `DisableEnumSerialization`, `DisableTupleReferenceConversion`, `Diagnostics`,
|
||||
`Diagnostic_Positions`, `LegacyDiscardedValueComparison`, `StrictNulHandling`, `StrictBinaryUTF8`, and
|
||||
`DeleteDeprecatedFunctions`. They have the same defaults as in CMake, except that
|
||||
`MultipleHeaders` is `false`. Set them with `-D` when setting up the build, or with the subproject name as prefix when
|
||||
the library is used as a subproject:
|
||||
|
||||
```shell
|
||||
meson setup build -Dnlohmann_json:Diagnostics=true
|
||||
```
|
||||
|
||||
The resulting compile definitions are part of the Meson dependency, the pkg-config file, and the CMake target.

A community-maintained fork, <a href="https://github.com/Johboh/nlohmann-json">Johboh/nlohmann-json</a>, publishes this library to both registries on each new release and can be used as an unofficial component/package for ESP-IDF and PlatformIO projects. As the library is header-only, it can otherwise be used directly by adding its <code>include/</code> directory to your component's/project's include paths, like any other integration method described on this page.</p> <!-- https://squidfunk.github.io/mkdocs-material/reference/tooltips/#adding-a-glossary --> <aside class=md-source-file> <span class=md-source-file__fact> <span class=md-icon title="Last update"> <svg xmlns=http://www.w3.org/2000/svg viewbox="0 0 24 24"><path d="M21 13.1c-.1 0-.3.1-.4.2l-1 1 2.1 2.1 1-1c.2-.2.2-.6 0-.8l-1.3-1.3c-.1-.1-.2-.2-.4-.2m-1.9 1.8-6.1 6V23h2.1l6.1-6.1zM12.5 7v5.2l4 2.4-1 1L11 13V7zM11 21.9c-5.1-.5-9-4.8-9-9.9C2 6.5 6.5 2 12 2c5.3 0 9.6 4.1 10 9.3-.3-.1-.6-.2-1-.2s-.7.1-1 .2C19.6 7.2 16.2 4 12 4c-4.4 0-8 3.6-8 8 0 4.1 3.1 7.5 7.1 7.9l-.1.2z"/></svg> </span> <span class="git-revision-date-localized-plugin git-revision-date-localized-plugin-date" title="October 7, 2026 20:20:05 UTC">October 7, 2026</span> </span> </aside> </article> </div> <script>var tabs=__md_get("__tabs");if(Array.isArray(tabs))e:for(var set of document.querySelectorAll(".tabbed-set")){var labels=set.querySelector(".tabbed-labels");for(var tab of tabs)for(var label of labels.getElementsByTagName("label"))if(label.innerText.trim()===tab){var input=document.getElementById(label.htmlFor);input.checked=!0;continue e}}</script> <script>var target=document.getElementById(location.hash.slice(1));target&&target.name&&(target.checked=target.name.startsWith("__tabbed_"))</script> </div> <button type=button class="md-top md-icon" data-md-component=top hidden> <svg xmlns=http://www.w3.org/2000/svg viewbox="0 0 24 24"><path d="M13 20h-2V8l-5.5 5.5-1.42-1.42L12 4.16l7.92 7.92-1.42 1.42L13 8z"/></svg> Back to top </button> </main> <footer class=md-footer> <div class="md-footer-meta md-typeset"> <div class="md-footer-meta__inner md-grid"> <div class=md-copyright> <div class=md-copyright__highlight> Copyright © 2013-2026 Niels Lohmann </div> </div> <div class=md-social> <a href="https://github.com/nlohmann" target="_blaLine truncated

Please see the Meson project for any issues regarding the packaging.

The provided `meson.build` can also be used as an alternative to CMake for installing `nlohmann_json` system-wide in which case a [pkg-config](https://json.nlohmann.me/integration/pkg-config/index.md) file is installed. To use it, have your build system require the `nlohmann_json` pkg-config dependency. In Meson, it is preferred to use the [`dependency()`](https://mesonbuild.com/Reference-manual.html#dependency) object with a subproject fallback, rather than using the subproject directly.

The provided `meson.build` can also be used as an alternative to CMake for installing `nlohmann_json` system-wide in which case a [pkg-config](https://json.nlohmann.me/integration/pkg-config/index.md) file and the CMake package config files are installed. To use it, have your build system require the `nlohmann_json` pkg-config dependency, or use [`find_package(nlohmann_json)`](https://json.nlohmann.me/integration/cmake/#external) in CMake. In Meson, it is preferred to use the [`dependency()`](https://mesonbuild.com/Reference-manual.html#dependency) object with a subproject fallback, rather than using the subproject directly.
|
||||
|
||||
The options that change the library's configuration are available in Meson as well, named like the [CMake options](https://json.nlohmann.me/integration/cmake/#cmake-options) without the `JSON_` prefix: `MultipleHeaders`, `GlobalUDLs`, `ImplicitConversions`, `DisableEnumSerialization`, `DisableTupleReferenceConversion`, `Diagnostics`, `Diagnostic_Positions`, `LegacyDiscardedValueComparison`, `StrictNulHandling`, `StrictBinaryUTF8`, and `DeleteDeprecatedFunctions`. They have the same defaults as in CMake, except that `MultipleHeaders` is `false`. Set them with `-D` when setting up the build, or with the subproject name as prefix when the library is used as a subproject:
|
||||
|
||||
```
|
||||
meson setup build -Dnlohmann_json:Diagnostics=true
|
||||
```
|
||||
|
||||
The resulting compile definitions are part of the Meson dependency, the pkg-config file, and the CMake target.
