Latest Updates In React Nat­ive & Their Benefits

20 Apr 2021

React Nat­ive Com­munity is spread across the globe to con­nect developers and React Nat­ive users with each oth­er. Oth­er than the Glob­al Sum­mits, Con­fer­ences, and annu­al meets, the React­Flux chat, for­um-like groups, and com­pany-based com­munit­ies; enable com­mu­nic­a­tions about the plat­form & under­stand it in a bet­ter man­ner. Moreover, this wel­comes more quer­ies and con­cerns regard­ing the plat­form, fea­tures, and its com­pat­ib­il­ity with oth­er com­pon­ents & sup­port­ing lib­rar­ies avail­able on the web. 

Tech­no­logy keeps evolving & so is the React Nat­ive plat­form. That’s what makes it a choice of sev­er­al people, includ­ing both users and the developers. Devel­op­ment is a nev­er-end­ing cycle. With every update & need of the industry, the arrival of updates is a sure shot. Here, we will be talk­ing about the React Nat­ive updates that the com­munity came recently in 2020 and the first quarter of 2021

The latest releases of React nat­ive in the reverse chro­no­logy are: 

  • React Nat­ive 0.64- Sup­port of Her­mes on iOS 
  • React Nat­ive 0.63- Enabling Log­Box by default 
  • React Nat­ive 0.62- Sup­port of Flip­per by default 

React Nat­ive 0.64- Sup­port of Her­mes opt-in on iOS 

Earli­er, Her­mes sup­port was only avail­able for Android. Now, with the release of React Nat­ive 0.64 latest in March 2021, the sup­port extends to build­ing an iOS app as well. 

Her­mes is a JavaS­cript engine that is optim­ized to run React Nat­ive & impro­vise its per­form­ance. It helps by min­im­iz­ing the util­iz­a­tion of memory, redu­cing down­load size & redu­cing time to inter­act­ive’ (TTI). 

React Nat­ive 0.64 comes with: 

  • It is enabling Inline Requires as a metro con­fig­ur­a­tion to improve the star­tup time by delay­ing the exe­cu­tion. It per­forms Babel trans­form­a­tion on input mod­ules and imports it to inline. It was avail­able as an opt-in con­fig­ur­a­tion for few years, and with this update, the option is enabled by default. 
  • React 17 is com­ing with a new JSX trans­form to impro­vise it to be able to use JSX without importing. 
  • Her­mes with Proxy Sup­port to enable com­pat­ib­il­ity in migra­tion of pro­ject pack­ages to make JavaS­cript engine default for Android. 

To make your React Nat­ive app com­pat­ible with the latest ver­sion 0.64, here are cer­tain soft­ware depend­en­cies to be addressed: 

  • Man­dat­ory- Xcode 12 and Cocoa­Pods 1.10 
  • Node Sup­port ran­ging from Node 1012
  • Flip­per bumped to 0.75.1
  • Drop-in Android API levels ran­ging from 1620

React Nat­ive 0.63- Enabling Log­Box by default 

They were address­ing the issues of errors, warn­ing and log sys­tem with the redesigned ver­sion of Log­Box con­sid­er­ing primary goals of con­cise, format­ted, and action­able logs. The Red­box, yel­low box designed Log­Box is set by default to attain the per­form­ance goals with the fea­tures includ­ing log noti­fic­a­tions, code frames, com­pon­ent stacks, stack frame was col­lapsing, and syn­tax error format­ting. LogBox.ignoreLogs() and LogBox.ignoreAllLogs() are depre­ci­ated from the API of Log­Box. With the next update of React Nat­ive 0.64, these options will be totally removed, so keep that in mind when upgrad­ing next. 

Moreover, React Nat­ive 0.63 comes up with: 

  • Nat­ive col­ours that enable you to change the col­our of the plat­form with the Plat­form­Col­or option and that of a dif­fer­ent but­ton with Dynam­ic­ColorI­OS for giv­ing the free­dom to cus­tom­ize your plat­form as per your choice. These access­ib­il­ity set­tings are in addi­tion to the default themes set­tings of Light/Dark mode. 
  • Min­im­ized the com­pat­ib­il­ity checks by drop­ping iOS 9 ad Node.js 8 sup­port to optim­ize the per­form­ance and imple­ment the latest secur­ity fixes. 
  • Change of iOS Lauch­screen from xib to story­board to provide app’s launch screen com­pat­ible with all the iPhone screens. 
  • Enables trouble-free ren­der­ing of <View/> inside any <Text/> without any size restric­tions on these components. 

React Nat­ive 0.62- Sup­port of Flip­per by default 

From the early months of the 2020s, React Nat­ive ver­sion 0.62 enables the sup­port of Flip­per by default. It is a developer tool­set for debug­ging Android & iOS mobile apps, which is applic­able for both exist­ing & upcom­ing apps. It is an extens­ible plat­form; you can pull the plu­gins from the mar­ket­place & install cus­tom ones as per your project’s require­ments. The provided fea­tures of this tool enable metro actions, view­ing crash reports, an inspec­tion of nat­ive lay­out out­put, logs, data­bases, and preferences. 

With React nat­ive ver­sion 0.62, we moved from Apple TV to react-nat­ive-tvos to bring Apple TV in line with oth­er plat­forms, namely React Nat­ive Win­dows and React Nat­ive macOS. If you are an exist­ing user of Apple TV pro­jects, you need to upgrade your Apple TV pro­ject to use react-nat­ive-tvos 0.62. also read about Top React Tools & Libraries

In addi­tion to these fea­tures, ver­sion 0.62 is com­ing with: 

  • The dark mode gives you the free­dom to switch between the col­our scheme. You can access it from the Appear­ance module. 
  • The exten­sion of React Nat­ive Upgrade help­er tools from ver­sion 0.61 to Upgrade-Sup­port in this ver­sion. It a Git­Hub issue track­er that sub­mits your issues regard­ing your con­tin­ued pro­jects to receive assist­ance from the community. 
  • Access­ib­il­ity improve­ments like the addi­tion of access­ib­il­ity­Value, miss­ing props on Touch­ables, onSlid­ing­Com­plete access­ib­il­ity events, change of switch­ing element. 
  • Tex­tIn­put changes by remov­al of onTex­tIn­put to assure W3C compliance. 
  • Remov­al of Prop­Types from core com­pon­ents to min­im­ize the size of React Nat­ive core app size.
